Heavy Structural Steel Products Fabrication

Openex is an expert in the fabrication of heavy-duty structural steel products. We can produce them to a customer’s exact specifications. So if you have a big construction project that requires large girders, look no further than the highly skilled craftsmen at Openex.

Structural steel girders play a critical role in any project that requires them. Their job is to directly transfer weight loads to the steel columns upon which they rest. The most common use of girders is in bridges. If the girders aren’t properly designed and fabricated, they run the risk of underperforming – a recipe for disaster.

Whether you need a typical steel fabricated structure or a multi-span highway bridge, Openex's staff are ready and able to meet your requirements.
