Professional Sheet Metal Fabrication Services for Your Business
Sheet metal fabrication combines cutting, bending, and assembly operations to transform flat sheets into enclosures, brackets, panels, and structural components.
About Sheet Metal Fabrication
Sheet metal fabrication is a comprehensive manufacturing process that transforms flat sheets of metal into finished products and structures. It encompasses multiple operations including cutting (laser, plasma, waterjet, shearing), bending (press brake), punching, welding, and finishing. Modern sheet metal fabrication shops use CNC-controlled equipment for precision and repeatability. The process is extremely versatile, producing everything from simple brackets to complex enclosures with multiple bends, holes, and hardware. Sheet metal fabrication is fundamental to industries ranging from HVAC and construction to electronics and aerospace.

Sheet Metal Fabrication FAQ
What is the typical sheet metal thickness range?
Sheet metal fabrication typically works with material from 0.015" (thin gauge) to 0.250" (1/4" plate). Thinner material is used for electronics enclosures; thicker material for structural applications. Material thicker than 1/4" is usually classified as plate fabrication.
What is a press brake and how does it work?
A press brake is a machine that bends sheet metal by clamping it between a matching punch and die. CNC press brakes can create precise bends at programmed angles and locations. Modern press brakes achieve bend angle accuracy of ±0.5° or better.
How are sheet metal parts joined?
Sheet metal parts are joined by welding (TIG, MIG, spot), riveting, hardware (PEM fasteners, screws), adhesive bonding, and interlocking tab-and-slot designs. The joining method depends on strength requirements, aesthetics, and disassembly needs.
Can sheet metal fabrication produce watertight enclosures?
Yes, with welded seams and proper gasket design, sheet metal fabrication produces watertight and even pressure-tight enclosures. These are common for outdoor electronics, food processing equipment, and marine applications.
What finish options are available for sheet metal parts?
Common finishes include powder coating, wet paint, anodizing (aluminum), plating (zinc, nickel, chrome), brushing, bead blasting, and passivation (stainless steel). The choice depends on corrosion protection needs, aesthetics, and environment.
