One of the most common resources in civil, commercial, industrial, government, architectural and resourcing is fabricated steel. Fabrication of steel structures requires a processed and streamlined approach. Items are based on tonnage and an increased number of components of smaller size, linked to form a final, larger structure, has become a fairly popular approach. Requirements and standards of quality for steel structures are at least as high as for other fabrication projects.
Steel Fabrication process is the process of grinding, cutting, welding, bending, burning, drilling, punching and generally crafting various steel detail components described in the detail drawings. It is a systematic process and every step is necessary and important.
DouHun’s process starts with coordinating the first steel to be fabricated with the steel stock. They just fabricate the steel to match the template and an accurate steel detail piece is produced. With the correct steel at their site and templates in hand, the fitters start the process in a number of material shapes including steel W shape beams, I beams, channels, plates, pipe, angles, and round bar. Testing procedures included a layout, dimensional check, visual weld inspections and ultrasonic weld tests. After this, a separate welding engineer fastens each pieces together to construct the shipping pieces or assemblies.
