Steel fabrication is the process of modifying raw steel materials (such as booms, ingots, slugs, bars, rods, and billets) into finished products designed for use in construction or assembly purposes. It involves various techniques like cutting, bending, welding, and more.

Common methods include:

Shearing: Cutting steel sheets or plates.

Cutting: Using tools like lasers or plasma cutters.

Bending: Shaping steel into desired forms.

Stamping: Creating patterns or designs on steel.

Punching: Making holes in steel.

Folding: Bending steel along straight lines.

Ask these questions:

  1. How experienced is the fabricator?
  2. What certifications do they have?
  3. Do they specialize in specific types of steel?
  4. What is their capacity?
  5. What equipment do they utilize?
  6. Do they offer in-house finishing services?

Consider factors like approvals, permits, site visits, safety checks, and realistic timelines. Effective communication with the fabricator is crucial.

Structural steel has lower carbon content (typically 0.04% to 0.3%) compared to regular steel (up to 2.1%). It is more pliable and suitable for construction purposes.

Everyday items like multipurpose pushcarts, storage shelves, stainless steel doors, grills, grease traps, and filters are essential steel fabricated products.

Evaluate their experience, communication, certifications, specialization, capacity, and equipment. A reliable fabricator ensures successful project execution.
