- Shearing: Best for straight, simple cuts.
- Plasma Cutting: Uses a high-powered jet of ionized gas for thick plates and intricate shapes.
- Laser Cutting: Provides precision and clean edges, ideal for detailed work.
- Oxy-Fuel Cutting: Suitable for heavy steel plates, using a gas flame and oxygen.
- Waterjet Cutting: Employs high-pressure water mixed with abrasive materials for a clean, cold cut.
5. Forming and Bending
This stage shapes flat plates into curves or angles:
- Press brakes and hydraulic bending machines create bends at precise angles.
- Rolling machines make curved or cylindrical parts.
6. Machining
Additional processing customizes the plates further:
- Drilling: Creating holes of specific sizes for assembly.
- Milling: Removing material to create slots, grooves, or custom shapes.
- Tapping: Creating threads inside drilled holes.
7. Welding and Assembly
Plates are joined to make larger parts or frameworks:
- Various welding techniques—such as MIG, TIG, or arc welding—create strong, seamless joints.
- Skilled welders ensure the structure’s integrity and visual appeal.
8. Finishing
The final touches make the product ready for use:
- Grinding and sanding: Smooth edges and surfaces.
- Painting or powder coating: Adds corrosion resistance and aesthetics.
- Galvanizing: Applies a protective zinc coating to steel plates.
9. Quality Inspection
Every fabricated plate or assembly undergoes rigorous quality checks for:
- Dimensional accuracy
- Weld strength
- Surface finish
- Cleanliness
