Custom Sheet Metal Fabrication Services
Sheet Metal Fabrication
Forming, bending, cutting, welding, and shaping for stainless steel, aluminum, steel, and specialty alloys. We fabricate thin-gauge to ¼-inch materials for brackets, enclosures, structural components, and more.
Waterjet Cutting Services
Our TechJet X2 4000 Series 5-Axis Waterjet cuts stainless steel up to 4 inches thick and processes materials such as glass, stone, rubber, plastics, foam, gasket materials, and various exotic materials.
Orbital Welding
Orbital welding is a computer-controlled GTAW process in which the arc rotates mechanically through 360 degrees. This allows for consistent, repeatable welds on sanitary stainless steel tubing and pharmaceutical-related components.
Tube Forming and Bending
We offer rotary draw bending, press bending, and freeform bending processes capable of shaping tubing for pharmaceutical, food-service, and process-equipment applications.
CNC Punching
Our turret punch presses support punching in stainless and mild steel, with digital tool management and tapping capability for a range of sheet-metal components.
Finishing and Assembly
We provide finishing services including #2, #4, #6, and #8 stainless-steel polishing, grinding, acid washing, and spot welding. We also assemble cabinetry, frames, guards, and components across food service, electrical, pharmaceutical, and OEM applications.
