Custom sheet metal enclosure manufacturing

Our Custom Sheet Metal Enclosure Manufacturing Services

Full-service enclosure fabrication from drawings, prototypes, and production runs through final assembly.

Custom Fabrication

Custom sheet and plate fabrication supports one-off prototypes, short runs, and production quantities for enclosures, chassis, brackets, panels, and precision metal assemblies built to customer drawings.

Laser Cutting

Precision laser cutting creates clean profiles, intricate openings, and tight-tolerance enclosure features across steel, stainless steel, and aluminum sheet or plate materials.

N/C Punching

Numerically controlled punching is ideal for repetitive holes, louvers, cutouts, and formed features, helping reduce cost on enclosure panels with high feature counts.

Metal Forming

Press brake forming turns flat sheet metal into enclosure bodies, covers, channels, angles, brackets, and complex chassis geometries with accurate bends.

Welding

Welding capabilities support structural joints, sealed corners, cosmetic seams, and multi-part weldments needed for durable enclosure and chassis assemblies.

Mechanical Assembly

Mechanical assembly brings fabricated components together with hardware insertion, riveting, weldments, and chassis systems so units arrive ready for installation or integration.
