Our Metal Fabrication & Mechanical Services

Full-service metal fabrication, precision cutting, forming, welding, finishing, and assembly for industrial applications.

Precision Parts

Custom sheet and plate components are fabricated to customer drawings, supporting precision commercial and industrial applications that require accurate dimensions and repeatable production quality.

Laser Cutting

Laser cutting produces clean edges, intricate profiles, and tight-tolerance shapes across steel, stainless steel, and aluminum for prototype and production fabrication needs.

N/C Punching

Numerically controlled punching creates holes, cutouts, louvers, and formed features efficiently, especially for repetitive patterns where speed and cost control matter.

Metal Forming

Press brake forming bends sheet metal into angles, channels, boxes, chassis parts, and complex geometries used in enclosures and mechanical assemblies.

Welding

Welding joins fabricated components for structural strength, sealed joints, cosmetic requirements, enclosures, chassis systems, and multi-part industrial weldments.

Mechanical Assembly

Mechanical assembly includes hardware insertion, riveting, chassis integration, and multi-part buildouts so customers can receive finished units ready for use.
