Use of CAD (Computer-Aided Design) software for detailed blueprints.
Structural analysis to ensure safety and compliance with building codes.
Material Selection:
Choosing the right grade of steel based on the project requirements.
Commonly used materials include carbon steel, stainless steel, and alloy steel.
Cutting:
Methods: Laser cutting, plasma cutting, and sawing.
Precision is critical to ensure components fit together seamlessly.
Bending and Shaping:
Techniques include rolling, pressing, and hammering.
Achieving the desired curvature or angles as per the design.
Welding and Assembly:
Welding joins the steel components to form the final structure.
Ensuring strong and durable welds through quality checks.
