Large Size Heavy Duty Steel Structures Fabricated Welding Products

Heavy Metal Fabrication Services: 

We offers extensive range of in-house metal fabrication services to provide custom-engineered metal products. Our heavy metal fabrication is a value added service for constructing equipment and various other configuration structures from unprocessed materials, based on our customer drawings. Our heavy metal fabrications are tailored to your unique requirements and are also available with reduced sourcing time and costs.

Some of our capabilities in heavy metal fabrication services include preparation of metal surfaces, by sawing, burning, bending, beveling, and rolling, fitting and welding the pieces into assemblies, machining the pieces and assemblies according to required tolerance and surface finish, and assembling the manufactured parts into semi-finished or finished equipment. We provide all fabricating services from piping to electrical connections. We also offer shop preparation and painting services to meet your requirements.
