Who We Are

  • We developed the press brake tub girder to help construct longer lasting, durable bridges that are easier to install.

    • Delivered fully fabricated with studs and galvanized coating — no field welding required

    • Bolted splices for longer beam lengths — simple turn-of-the-nut method for tightening

    • Lightweight beams increase reach and allow for reuse of existing foundations

    • Galvanized coating provides 100 year maintenance-free service life

  • Short-span steel bridges have less impact on the environment compared to concrete bridges.

    • Less embodied CO2 emissions

    • Less energy required

    • Made from 90% recycled steel

    • Fossil-free steel available upon request

  • Our press brake tub girder is half the material volume and weight of prestressed concrete beams.

    • Lower freight costs — more load on one truck

    • Easier to handle and stockpile

    • Less equipment — small crane, backhoe or sky track to unload and install

Expert Reviews

“The press-brake-formed tub girder system offers significant cost savings, ease in shipment and fabrication, accelerated construction and design versatility, with the potential to replace thousands of short span bridges over the next decade.”

— Short Span Steel Bridge Alliance

“I think very soon you’re going to see this approach used again and again.”

— Luis Plancarte, of the Imperial County California Board of Supervisors, on county’s decision to install a PBTG bridge.

“After all is said and done, it was way easier than a precast deck beam.”
