Steel Fabrication & Erection
The process of steel fabrication involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. The entire steel fabrication process is systematic and requires utmost planning, precision, and knowledge. Steel fabricators are well aware of all the crucial steps and measures that need to be taken care of in the fabrication process. Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles and plates.
These steel members must be accurately fabricated before assembling them together. All component parts of these members are fitted-up temporarily with rivets, bolts, or small amounts of welds. Various fastening methods are employed to deliver different types of finishes. Finishing is generally performed by milling, sawing or other suitable methods.
It’s important to understand how structural steel structures are designed before assembling them together.
There are four primary tasks that need to be considered before the steel erection process:
It is extremely important to establish the foundations and confirm if they are suitable and safe for erection to commence
With the help of cranes or sometimes by jacking, lifting and placing components into position is essential. Additionally, to secure the components in place, bolted connections are made but they may not be fully tightened. Similarly, bracings may not be fully secured.
Aligning the structure is essential, principally by checking that column bases are lined and leveled and columns are plumb. To allow column plumb to be adjusted, packing in beam-to-column connections may need to be changed.
Last but the least, bolting-up is required, which means completing all the bolted connections to secure and impart rigidity.
