Large Fabrication & Welding

Metal Fabrication is building 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 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 a range of machining and finishing equipment. We have cranes that can lift up to 250 tons and multiple medium-size fabrication bays.

Materials Center

Materials we work with include Carbon steel, Mild steel, Galvanize, Stainless steel, Duplex ss, Aluminum, Corten, Inconel, Monel, Hastelloy, Chrome, Titanium, and Nickel alloys to name a few. 

Our full-service processes include Cutting, Forming/Braking, Rolling/Bending, Welding, Sandblasting, Painting, Machining, Drilling, Punching, Grinding, Inspection.


All metal fabrications begin with cutting – we carry out laser cutting (most precise), plasma cutting, water-jet cutting, and torch cutting, and also include shearing and sawing.
Thickness: 4mm~600mm, Max width: 8000mm, Max length:25000mm.


Thanks to our team of skilled professionals and our array of fabrication equipment, we are able to weld in a number of different materials and utilize the best welding processes.
High-quality performance is maintained at every stage of fabrication.
