What Is Custom Sheet Metal Fabrication?

Custom sheet metal fabrication involves a series of precise metal manufacturing processes that are used to produce a finished product from a flat sheet of metal. Custom fabrication differs from mass-produced components in that it is built to the customer's specifications, dimensions, tolerances and desired performance.

The manufacturing process usually consists of:

• CAD design and engineering
• Material selection
• CNC laser cutting
• Turret punching
• Precision bending
• Welding and assembly
• Surface finishing
• Quality inspection
• Packaging and shipping

Every stage helps in creating long-lasting and efficient metal parts that align with specific customer requirements.
