DIS-TRAN Steel’s Quality Engineering Practices Ensure Towers Are Built to Last

Posted by DIS-TRAN Steel on Aug 23, 2016 12:57:19 PM

On Dec. 14, 2009, the failure of a broadcast tower in Tulsa, Oklahoma had engineers scratching their heads. The chief engineer said when the guy wire was tested a few months earlier “everything seemed fine.”

Remarkably, 31% of all substation tower failures occur because of the construction crew’s poor judgment or a lack of basic engineering know-how, according to a recent Consolidated Engineering Inc. (CEI) report. Engineering oversights can cause a significant risk to the integrity of a tower and its foundation, which can ultimately lead to collapse.

DIS-TRAN Steel has built its company on simple values backed by honest customer relationships. Since 1965, customers have put their trust in us to deliver products – from simple substation structures to complex transmission poles – that are made using the best manufacturing process and the highest-quality engineering in the industry.

We offer the kind of security that comes from knowing exactly who is designing and fabricating your structures and how.

Unfortunately, some standards aren’t consistent across the industry. The CEI report found the top five causes of tower failure are caused by construction errors, ice, aircraft, special winds and anchor failure. The Tulsa tower’s failure was attributed to the latter two factors.

A CEI forensic specialist found in every wind induced tower failure he investigated, the tower wouldn’t have passed the current design code. It is important to design, manufacture and erect per current design codes to minimize the risk of poor structure integrity.  Quality issues are not only costly, but dangerous as well.

So how can you ensure you’re working with the right manufacturer?

  • Look for solid investments in the latest equipment and technology
  • Attention to best practices and quality assurance
  • A focus on hiring the most experienced engineers
  • A commitment to top-notch customer service.

Posted by Wendy Gintz on May 7, 2015 1:30:00 PM

It's been awhile, but we are still at it...  Thats, hopefully createing ueseful tips that make your job easier.

AnchorBolt

We have had a sort of series of Take2s referencing Anchor Bolts.  For this edition we will look at calculating the embedment of steel transmission structures.  Please feel free to go back and view the two previous Take2 Blog posts.

     Anchor Bolt Loads
     Anchor Bolt Design

What you will hear about...

  1. What to consider when calculating the embedment.
  2. What resources to use.
  3. A working example
  4. Additional information to consider

   

Thank you for viewing the DIS-TRAN Take2. We look forward to your feed back.  Please leave any comments or questions you may have about transmission pole or anchor bolt design below.

Until next time...

More than just Standard Steel Poles...

Posted by Brooke Barone on Sep 20, 2012 10:07:00 AM

Aerial view of our plant in Pineville, LAIt’s always hard when you’re first starting out and trying to establish yourself and your company, but with perseverance and an appetite for success, growth is inevitable.

In the beginning, DIS-TRAN only manufactured standard shape steel structures; however, we were always in need of steel poles. We established a great relationship with a company here in Louisiana who we purchased our steel poles from until a larger company came in and bought them out and shut their plant down. This forced us to reach out to other companies across the country.

Right around this time, in the late 90’s, cell phones were rapidly catching on and cellular towers were going up everywhere. Contractors were purchasing tons of steel pole capacities, so it became very hard for us to get service. One of the problems that we ran into was that we would ship the structural steel out to a site, but then have to wait a month or so for the steel poles to arrive. We all know how that story ended-with unhappy customers.

So, in 1995, DIS-TRAN decided to open up its own steel pole shop and dabble into the market. With only 12 employees in the beginning, it was a huge learning curve, but as the industry grew and became more advanced, so did DIS-TRAN.

DIS-TRAN Steel Pole and DIS-TRAN Steel Fabrication were two separate companies at first, but after we realized we were doubling our internal workload, we decided to merge the two in 2010 to become what is now DIS-TRAN Steel, LLC. In 2006, DIS-TRAN Steel Pole and DIS-TRAN Steel Fab had 149 employees total, and now, six years later, DIS-TRAN Steel has more than doubled that number to 321.

Over the years, we’ve realized that there are some misconceptions about the capabilities of DIS-TRAN Steel since we initially started off just manufacturing steel structures. But we can also design, detail, fabricate and deliver tapered tubular steel structures for the utility industry. 

Our engineering and detailing capabilities allow DIS-TRAN Steel to pursue and be involved in highly technical design projects. With 18 in-house detailers and 10 engineers, including 4 Licensed Professional Engineers (P.E.), we can design any steel structure for the utility industry, whereas some of our competitors require shop-ready drawings.

Whether they are pre-engineered poles, engineered transmission poles or taper tubular substation structures, DIS-TRAN Steel can fabricate it. As one of our guys says, we can design steel structures with as little information as a stick figure on a napkin to fully-detailed drawings because of our in-house expertise and resources.

The investment we have made in our employees goes hand-in-hand with the investment that we have made at our plant, with 4 expansions in 16 years. Customers are always surprised when they tour our plant in Pineville, LA because of how large and advanced it really is. It’s not just this little fabrication shop tucked away in the swamps.

Our state-of-the-art facility is just as large as any other steel fabricating facility in the U.S., sitting on about 60 acres with 300,000 square feet under roof manufacturing space. Some of our most prized possessions at our plant include a fully automated 2500 ton, 60 foot Press Brake with a one-of-a-kind automation software package that our plant operators actually helped design. We also have in-house high definition plasma cutters, robotic welding systems, CNC controlled seam welders and CNC punches for standard shapes.

Something that also surprises many is that we can also supply wood transmission arm assemblies and distribution crossarms through our sister company DIS-TRAN Wood Products, LLC. DIS-TRAN Wood Products has two fabricating facilities, one in Pineville and the other in Vancouver, WA.

Throughout the years, DIS-TRAN has made the investment to meet the demands of the growing industry, and has made sure to keep up as the elite supplier, consistently providing the highest quality products.
