- Bending: Press brakes create angles, tabs, and channels.
Advanced fabricators offer CNC folding, deep drawing, and even 3D-shaped panel forming.
Step 5: Prototyping and Verification
Before full production, fabricators often create a prototype:
- Check fit, shape, and features.
- Make adjustments to the design as needed.
This minimizes waste and costly rework.
Step 6: Finishing
Most sheet metal parts are finished for aesthetics or corrosion protection:
- Painting
- Powder coating
- Plating (chrome, zinc, etc.)
- Polishing or brushing
Some decorative projects require custom engraving or stamping.
Step 7: Production and Inspection
Once approved, your unique sheet metal parts are produced, inspected, and prepared for shipping or installation.
