Large Fabrication & Welding

Metal Fabrication is the building of metal structures through cutting, bending, pressing, plate rolling, welding, assembling, machining and finishing raw pieces.

We offer complete turnkey fabrication and assembly for projects that range in size from moderate to epic. Our 730,000 square-meter facility houses a full range of heavy duty plate fabrication machinery, state-of-the-art robotic and manual welding stations, an oversized stress-relief furnace, and range of machining and finishing equipment. We have cranes that can lift up to 250 tons as well as multiple medium-size fabrication bays.
