2015 ETS Structure Conference - Broken Down DIS-TRAN Style

Posted by Wendy Gintz on Nov 16, 2015 2:30:00 PM

Did you take good notes during your sessions at the 2015 Electrical Transmission and Substation Structure Conference. Don't worry, we've got your backs.

Buzz Words from ETS Structure Conference

These are a few of the buzz words remembered by the DIS-TRAN Steel Engineers during the industries most electrifying conference.  While so many of the worlds finest engineers from manufactures, contractors, epc, and utilities from around the world gathered to Talk the Talk, there may have been a few that were not able to participate.  Doesn't make you any less finer in our minds. 

Here we hope to briefly describe some of the sessions that our engineers found most interesting and some of their key take aways.  How often do you get to read the notes of other engineers.  Pretty exciting!

Structural Analysis 1 - Mike Miller, P.E., M.ASCE
Presentations based on the most common engineered structure, tubular steel poles and testing these structures.

  1. It's benefitial to see results of full scale tests, especially when confirmating the designs are adequate.
  2. The prefered is not always the best. Options must be reviewed.
  3. There is simplicity in Slip Joints AND they work.  
  4. Using a non-traditional structure configuration can be a more efficient solution.

Special Design Considerations - Marlon Vogt, P.E., M.ASCE
We are not always only looking at the functionability of a structure but sometimes it's aesthetic value can be a huge issue.  In these  papers a worldwide view on structure aesthetics was discussed.

  1. BOLD (Breakthrough Overhead Line Design) has changed the transmission line needs to be more appealing.
  2. Using the induction heat bending process for bending tapered tubular sections.
  3. The more visual transmission lines are becoming the more emphesis is pused on aesthetics.
  4. Engineers play a key role in the NEPA team providing technical support.
  5. Utilities are researching alternative materials for transmission design and applications.

Structural Analysis 2 - Robert Nickerson, P.E., F.SEI, M.ASCE
Learn how lattice tower analysis is still relevant, the challenges and the eccentric connections of these towers.

  1. The use of graphical analysis can be done with a CAD software along with full scale diagrams can be created.
  2. Two-Deminsional CAD tools have no automatic feature for evaluating eccentricities.  The actual behavior of the structure can can differ from the theoretical model.

Construction Challenges - Dana Crissey, P.E., M.ASCE
Following teams that were faced with challenges and overcame them by thinking innovatively to get their projects done.

  1. Starting from complete scratch involves creating standard/best practices and designs (foundation and structural) from the ground up.
  2. River crossing foundations can be complicated due to the land around the river where the soft adn highly variable soils can decrease accessibility.
  3. Safety can be a challenge and has led to added specifications in the design phase which  incorporate fall protection requirements.

Rerating and Upgrading - Tim Cashman, P.E., M.ASCE
Making the decision of fixing and tearing down lines to rebuild is the questions these papers discuss.  Hightlights from three upgrade projects to overcome congestion.

  1. Increased load requirements calls for improving the existing systems and decisions must be made on how to most effectively accomplish this.
  2. Major considerations are: old vs new codes, life expectancy of the existing structures and should you reinvorce or rebuild.

In conclusion, the theme this year seemed to be focused around Challenges and Solutions.  Of course, that is what Engineering is all about.  Over the last three years, since the last ETS Structure Conference an engineers dream and dread are based on solving problems.  When you think of Creativity we tend to think of Artists, Graphic Designers, Marketers but these Engineers have Creativity mastered the art of engineering.  Whether the challenge was Cost, Time, Design, Right of Way, Aesthetically pleasing to the eye or Environmental they were all addressed by using best practices and thinking outside the box, CREATIVELY.

How have you used what you learned at the ETS Conference during your day to day activities?  What take aways did you have? We would love to hear your point of view.

Pros and Cons of using 3D Detailing for Steel Structures...

Posted by Wendy Gintz on Sep 2, 2015 2:30:00 PM

article5Trying to find technical blog topics that can be useful and interesting can be difficult.  Welcome to the world of Blogging some may say.  However; making things easier and more efficient is always a step in the right direction.  The advancement of steel detailing software has helped move the process of design, steel detailing, steel fabrication and steel construction to a streamlined efficient flow of information.

There are a large number of detailing softwares available from manufacturers such as… Tekla, Soft Steel, AVEVA, AutoDesk and SDS/2.  

More and more you see the rise of 3D Detailing to enhance to the visual representation of structures. Below are some Pros & Cons of 3D Detailing:

Pros -

  • After creating a 3D model, all needed drawings can be generated automatically.
  • Drawing in 3D provides you with a better visual representation of the steel structures being detailed.
  • The drawings/model are done to scale so it’s more accurate.
  • A change to the 3D model automatically updates the entire model & all associated drawings.
  • A Bill of Material can be generated from the model, reducing the likelihood of errors.

Cons - 

  • The costs/training of 3D modeling programs are higher than traditional detailing software.
  • It’s complex process to build a 3D model.
  • You must build a 3D model for each steel structure to get the drawings generated.

Not only do we want to consider the Pros & Cons of a product but also how they may affect all those involved.  Below is a list of how this software and the end product effect the user.



3D modeling has improved the quality of detail drawings largely by reducing the human element which may cause unnecessary errors.  Once the model is created, all drawings associated with model will be accurate (assuming the model is correct) and there will be no contradicting drawings.  Additionally, any last minute changes will be carried throughout the drawing set by making the change in one place.  There’s no need to worry about whether or not a change was made to every drawing.

Steel Fabrication

3D modeling affects fabrication by ensuring accuracy in the fabrication drawings.  Also, with the drawings done to scale, the fabricator sees exactly what the completed piece should look like.

Construction/Structure Erection

Creating a visual image of the structures ahead of time and being able to identify any potential connection errors reduces field erection issues.  Increasingly complex structures can be created with the ability to see how they will fit together and be erected much easier than with 2D modeling.

I would like to say a HUGE THANK YOU to Chase Baum for helping me put together this information. He is a Detailing Supervisor for DIS-TRAN Steel.  We use AutoDesk Advance Steel as our 3D Detailing Software of choice.  This technology allows our software to generate DSTV files which communicate with our Shop Machinery. When the machine fabricates the main members it has the capability to scribe welded part locations, weld symbols, and piece marks.  This shows the fitters/welders exactly where the parts are to be welded and the weld size to use, without looking at a drawing.  This is HUGE in our industry.

Let us know if you have any additional Pros or Cons you would like to contribute to the converstation.  We would love to hear from you on how you battle the difference in Traditional 2D and the Enhanced 3D Software.

8 Major Markets That Use Composites

Posted by Melissa Hines on Aug 10, 2015 2:26:00 PM

A World Full of Composites

One might be surprised to find out that composites have become a part of our everyday lives. So what are composites? Composites are formed when two or more materials with different physical and chemical properties are combined to produce a material with characteristics different from the individual components.

Composite material is widely used because it is light weight, high strength, durable, corrosion resistant, nonconductive, low maintenance and allows for design flexibility. In today's market, structures made of composite have a longer life and a higher strength to weight ratio than those made of traditional material. This versatile material is used in such a variety of applications that the overall composite market has to been divided into the following major segments.

  • Aerospace - The aerospace market is one of the largest and most important of the composites industry. Commercial, military and space craft all make substantial use of composite material both inside and out. Some applications of composite on aircrafts include propellers, primary wing and fuselage structures, floor boards and flight control surfaces.
  • Automotive - Composites are being used to make lighter, safer and more fuel efficient vehicles. Composite material can withstand very intense heat and speed and will not rust or corrode like steel or aluminum. The use of composites in vehicles has given the automobile designers free rein, as these materials can be easily molded into any shape or size.
  • Construction/Infrastructure - Composites are used in various architecture and infrastructure applications. Some of these applications include the repair and replacement of roads, bridges and pilings. Homes and offices also use composite material. Bathroom fixtures, swimming pools and wall panels are just a few of the items around your home that may be made of composite.
  • Defense - The military has long used composites in many applications. Some of these applications include fighter jets, helicopters and watercraft. The strength and durability of composite material is perfect for the demanding performance of these applications.
  • Marine - The marine market is deeply penetrated by the composite industry. Yachts, sailboats and naval ships all use some form of composite material. Composites are very suitable for these applications because they can withstand the harsh marine environment.
  • Mass Transit - Trains, buses and subways make extensive use of composites. Many of the air conditioner enclosures, vehicle body panels and interior parts and components found in these modes of transportation are made of composite material. Composites offer overall weight reductions and improved energy effeciency. 
  • Sports and Recreation - Composites used in sporting goods is almost a given these days. Golf clubs, tennis rackets, hockey sticks, fishing poles, canoes and bicycles all benefit from the light weight and high strength of composites. The use of composite material in recreational activities will continue to increase.
  • Energy/Electrical- Composites are being used to make turbine blades, solar panel frames, pole line hardware, substation equipment, utility poles and crossarms. Since composites are nonconductive, this makes them very suitable for electrical products. Composites can also stand up to severe weather and wide changes in temperature making them ideal for the great outdoors.

Composites are all around us. This material builds bridges that won't rust, turns wind into electric power, improves fuel efficiency in cars, trucks and trains, creates recreational options that make our life enjoyable and so much more.

Are there any products you use on a daily basis that are made of composite material? Do you like the way composites are being used in today's market?

Steel Structures Can be a HOT Business

Posted by Wendy Gintz on Jul 17, 2015 2:00:00 PM

I just got back from vacation and it was HOT.  I started thinking that this must be the hottest time of the year for most of us.  It got me wondering about the Safety of all the folks out there in the manufacturing industry. I went to the best source I know, Tim Adam with DIS-TRAN Steel.  Grant it, I work in an office (thank goodness), but I work with a bunch who do not get the luxury of air conditions and fans.

In the Utility Industry you have a vast array of people doing outside labors.  Contractors erecting structures, truck drivers loading/unloading trucks, field project folks supervising as well as the steel fabricator and manufacture the steel structures (this one hits close to home).  It’s important to remember that Safety must come FIRST, no matter what you’re doing.

When it's hot, drink plenty of water!

 Below is a list of Heat Related Illnesses:

  1. Heat Stroke - is the most serious form of heat injury and is a medical emergency. Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps and heat exhaustion. But it can strike even if you have no previous signs of heat injury. Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes. The hallmark symptom of heat stroke is a core body temperature above 105° Fahrenheit. But fainting may be the first sign.  If you suspect that someone has heat stroke -- also known as sunstroke -- you should call 911 immediately. Until help arrives, move the victim to a cool area and remove excess clothing. Fan and spray them with cool water. Offer sips of water if the victim is conscious.

    It is important to hydrate your body well prior to being subjected to hot work environment. Drink and eat a well-balanced meal the night before and have a good breakfast prior to a work shift. Fruit and fruit juices are good to help hydrate your body and restore electrolytes. Do not consume energy drinks as they are full of sugar and your body has to work harder to digest them. Gator aid and Power aid help restore electrolytes but need to be consumed in a 1 to 3 water bottle ratio to help prevent kidney stones. Watch the color of your urine. If it is bright yellow, you are not consuming enough water.

  2. Heat exhaustion - can occur after you've been exposed to high temperatures for several days and have become dehydrated. Symptoms include confusion, dizziness, headache and fatigue.  Although heat exhaustion isn't as serious as heat stroke, it isn't something to be taken lightly. Without proper intervention, heat exhaustion can progress to heat stroke, which can damage the brain and other vital organs, and even cause death. If you, or anyone else, have symptoms of heat exhaustion immediately get out of the heat and rest, preferably in an air-conditioned room. If you can't get inside, try to find the nearest cool and shady place.

  3. Heat cramps - are painful, brief muscle cramps. Muscles may spasm or jerk involuntarily. Heat cramps can occur during exercise or work in a hot environment or begin a few hours later. Heat cramps usually involve muscles that are fatigued by heavy work, such as calves, thighs, and shoulders.  Painful cramps occur in the arms, legs, or stomach while on the job, or later at home. Move to a cool area at once if cramping is experienced. Loosen clothing and drink cool water or an electrolyte replacement beverage, such as Gatorade®. Seek medical aid if the cramps are severe, or don't go away.

  4. Dehydration - occurs when the loss of body fluids exceeds the amount that is taken in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking.  Along with the water, small amounts of electrolytes are also lost. When we lose too much water, our bodies may become out of balance or dehydrated. Severe dehydration can lead to death.  See the Dehydration Urine Color Chart help identify whether you may be dehydrated or not.  Click here

As a quick resource OSHA has Quick Cards with valuable information for quick references.


Working or playing in a hot environment puts stress on the body and when combined with physical work, loss of fluids or fatigue it could have detrimental effects.  WATER is crucial and remember to not push yourself beyond your limits.

At DIS-TRAN Steel, we have made it a priority to educate and remind all of our employees the symptoms and prevention techniques.  Our Safety Manager keeps in contact with all the supervisors about weather conditions, heat indices, and conducts multiple heat related Tool Boxes.

How do you keep cool while working in a HOT environment?  We would love to hear from you so please use the comment section below.

3 Transmission Structures Broken Down

Posted by Wendy Gintz on Jul 7, 2015 9:45:00 AM

When designing transmission structures...

it’s not as simple as saying “ok, I want self-supporting tangent mono poles with delta configuration for my entire 80 mile stretch.”  While that idea might be more economical than having h-frame or 3-pole structures, it’s just not practical.

Ultimately, the wire configurations determine which type of structure will be used, and typically there will be a mix of these structures in order to follow the right-of-way through small or tight turns. Right-of-ways go alongside or through interstates, highways, fields, woods and even water, so an engineer must keep all these situations in mind when designing.

Three common transmission structures:

  •  Tangent
    • Used when transmission route is straight
    • Generally, no longitudinal loads on the structure
  • Angle
    • Used when transmission route changes direction
    • Used from anywhere less than a 5 degree angle to a 90 degree angle
  • Dead-End
    • As name applies, dead-ends are designed to take the full component of every wires’ tension
    • Does not necessarily mean end of transmission line 










Whether the structures are tangent, angle or dead-end, wire phases can run in multiple configurations.  Horizontal Configurations provide the lowest profile. Vertical Configurations require the minimum width right-of-way. And Delta Configurations is an attempt to use the value of both horizontal and vertical configurations to maintain phase clearances.

Transmission structures can be classified as either self-supporting or guyed.

Self-Supporting Structures do not use guys: meaning they are not tied to the ground or any other structure in a way that offers additional support. They are better for restrictions to right-of-ways and tend to have loads small enough to not warrant guys.

Guying of structures is used to support the structure and allow for a more economical design in both the steel structure and foundation. Guying reduces bending and deflection. However, the downside is that it requires more right-of-way. 

*Here are some main contributing factors to keep in mind when deciding on whether or not to guy a structure:

  • Structural loading
  • Right-of-way requirements
  • Aesthetic design criteria

**Here are some other contributing factors you may want to consider:

  • Line voltage
  • Electric air gap clearance requirements
  • Ground clearance requirequirements
  • Insulation requirements
  • Number of circuits to be supported
  • Electric and magnetic field limits

There is so much to learn about Transmission Structures.  What questions do you have?  We would love to hear from you so please leave a comment below.

3 Common Crossarm Preservatives

Posted by Melissa Hines on Jun 22, 2015 11:03:00 AM


Are you treating your wood right?

Wood utility poles and crossarms are common objects seen throughout our communities along the streets and in our yards. These poles and crossarms are used to support and run electrical lines to our homes and businesses - making these products vital to our daily lives. Prolonging the useful life and structural integrity of these items is aided by treating the wood prior to installation.

Wood treatment refers to protecting wood from damage caused by insects, fungi, decay, climate and extreme weather conditions. Treating wood with the right chemical preservatives can extend the useful life and protect it from the harsh environment. Choosing the right wood preservative can save an utility time, frustration and money. The three most common wood treatments include:

  • Pentacholorphenol (Penta)
  • Chromated Copper Arsenate (CCA)
  • Creosote.

Pentacholorphenol (Penta) has been a preservative and maintenance staple of the Canadian and American utility industries for more than 60 years. Penta is a broad spectrum biocide and was previously used in herbicides, algaecides, fungicides and disinfectants. Today, the use of Penta in the U.S. and Canada is limited to wood preservation applied by trained-certified pesticide applicators. The production and use of Penta is regulated by the EPA and is an approved preservative in the American Wood Protection Association. (AWPA) Since its introduction in the utility industry, Penta has become the preferred wood preservative for poles and crossarms and is used extensively for treatment of laminated beams since it will neither wet the wood nor effect the glue joints. Penta can be used as a wood preservative for both Douglas Fir and Southern Yellow Pine crossarms.

Chromated Copper Arsenate (CCA) is a water based wood preservative. It is a mix of chromium, copper and arsenic. Recognized for the greenish tint it imparts to wood, CCA has been extremely common for many decades and is used primarly on Southern Yellow Pine poles and crossarms. DIS-TRAN Wood Products, LLC provides this alternative wood preservation to its customers making up about 5% of the crossarms we supply.

Creosote is one of the oldest of the commercial  preservatives. It is made by distilling coal tar and is often thinned with a light oil such as diesel fuel or mineral spirits. The color of Creosote is usually dark brown to black with an oily appearance and odor. Most wood treated with Creosote is used in marine pilings, utility poles and railroad crossties.


At DIS-TRAN Wood Products, LLC, we not only manufacture a complete line of Douglas Fir and Southern Yellow Pine crossarms, but we also house our own treatment facility. Our treatment plant is located adjacent to our manufacturing facility in Pineville, LA. DIS-TRAN Wood Products, LLC have three trained-certified applicators onsite who follow all industry and environmental standards. With these three professionals onsite, DIS-TRAN Wood Products, LLC can treat approximately 1,300 arms with Penta on a single eight hour shift. Having our own onsite treatment plant allows us to have a fast response for storm emergenies. About 95% of the crossarms we manufacture are treated with Penta. 

Using the right chemical preservative for treating wood can greatly increase the life span and save a lot of time and money. Is there a wood preservative treatment you prefer to use? Would you like to see DIS-TRAN Wood Products, LLC offer an alternative wood treatment?  Leave us a comment below.  We would love to hear from you.

Tips for Successful Galvanizing Touch-Ups in the Field

Posted by Wendy Gintz on Jun 3, 2015 8:26:43 AM

“How do I successfully touch-up galvanizing in the field?”

This is a common question about substation and transmission structures.  There could be a number of reasons why touch-ups may be necessary in the field.

  • Extremely rough handling
  • Installation techniques
  • In-service conditions


There are certain factors to consider when repairing galvanizing in the field, such as: the size of the area to be repaired, the ease of use of the repair material and the performance of the repair method.  There are also standard specifications to follow for the repair of galvanized coatings.  ASTM A780 covers methods used to repair damaged hot-dip galvanized coating on hardware and structural shapes as well as required coating thicknesses.  There are three acceptable forms of touch-up.

  1. Zinc Based Solders - achieved by applying zinc alloy by stick or powder form.  Most common alloys are zinc-tin-lead, zinc-cadmium and zinc-tin-copper.  To prepare the surface use a wire brush, lightly ground, or mildly blast clean and remove all weld flux and spatter.  The area being repaired needs to be preheated to 600 F.  This is the most difficult method of repair.
  2. Zinc Rich Paints - either by brush or spray is applied to a clean, dry surface. The paint must contain between 65% to 69% metallic zinc by weight or greater that 92% by weight in dry film.  To prepare the surface the area must be cleaned either be blasted, power tool cleaned or even hand tools (wire brush). This is the most commonly used field repair method and can easily be done without a need for blasting or power tools. Zinc-rich painting should be avoided in high humidity and/or low temperatures.
  3. Metallizing achieved by melting zinc power or zinc wire in a flame or electric arc. The zinc used is minimum of 99.5% pure.  To prepare the surface it must be blasted cleaned to SSPC-SP10/NACE No.1 near white metal and must be free of oil, grease, weld flux residue, weld splatter and corrosion products.  The cleaning must include surrounding, undamaged coating.  Spraying should be done by a skilled worker in horizontal overlapping lines to create a uniform thickness.  Not recommended for high humidity locations.

The coating thickness of the repaired area must match the coating thickness of the surrounding area. If zinc-rich paint is used, the coating thickness must be 50% higher, but not greater than 4.0 mils.


Be sure to discuss any touch-ups with your steel fabricator or galvanizer. They may have suggestions on which method has worked best for certain circumstances.  Final coating thicknesses need to be agreed upon between customer and vendor and be measured by the methods in ASTM A 123/A 123M.  Remember that the surface of the repaired coating should be free of any lumps, course areas and loose particles.

9 Must Haves for a Steel Structure Specification

Posted by Wendy Gintz on Apr 22, 2015 3:30:00 PM


Specification are to Steel Structures like...
Cherries are to a Banana Split.

Specifications come in all shapes and sizes.

From the very informal 3 page document to the all-encompassing formidable documents.  The specification is a tool for the Owner (End User) to convey their minimum project requirements to the supplier.  Defined by Wikipedia, it is a set of documented requirements to be satisfied by a material, design, product or service and also a type of technical standard.

In the utility industry we see specifications presented in many different formats.  As a result, it is very important that a specification be clear and easy to follow.  Be careful about providing multiple specifications and documents that start contradicting one another. In these wordle_2situations the Owner’s requirements and overall message can get lost in a sea of documents resulting in different interpretations by the suppliers.  This can ultimately lead to proposals that can’t be compared properly, Owners not getting what they want, or additional unforeseen costs. When it comes to fabricating substation and transmission steel structures there are many variables that need to be relayed during the design, detail, and fabrication phases.  These specifications provide that direction.  Whether you are using an already created specification, updating a previous version or crafting a brand new one, there are certain sections you want to include.  Below are 9 sections that are not to be missed when deciding the content for your specifications. 

  1. Purpose/Scope – This is the heart of the document.  This is the owner’s chance to define the purpose of the document and clearly layout their expectations for the scope of work.  Example: Intended to serve as a system wide guide for structural design of steel structures.
  2. References – This section typically lists out the required design standards and any other applicable documents.   (e.g. ASTM Standards, ASCE Design Stanards, etc.) 
  3. Submittals – This section typically covers the owner’s expectations of any document to be submitted by the supplier.  This includes things like bid proposal requirements listing out the needed forms and design summaries.  It also covers formal design and drawing submittal requirements.
  4. Loading and Geometry – If the scope of work includes design, this section typically covers the minimum information needed by the Structure Designer to design the structures.  This would include things like loading criteria, unique weather conditions and terrain for the service area, and any other usual loading conditions the designer should consider.    This section also covers the different structure types, general layout of the structures, and the types of connections permitted.  (e.g. slip-fit vs. flange, embedded vs. base plated)
  5. Design – This section typically includes any restrictions to the design, material, field erection, fabrication, etc.  Examples of this include anchor bolt circle limits, minimum material thicknesses allowed, deflection limits, aesthetic preferences, weight limitations, etc.
  6. Fabrication – This covers owner’s expectations of workmanship and quality. 
  7. Finishing/Coating – What type of coating is supposed to be used such has galvanizing, painting, sandblasted, etc.
  8. Inspection – This section typically covers the type of inspections and testing required for the project. 

Of course these are just a few of the main sections.  There may be other sections that pertain to your specific product need, corporate formalities and/or industry.  No matter what your final Specification Document instills, it is important that you and those that use them agree on what is expected from a product and/or service.  This form of communication between the two parties can be a key component to a successful project.

How do you communicate your expectations to your vendors?  We would love to hear from you so please leave a comment below and let us know if this information has been useful.
