Our Capabilities
Our facility handles sheet metal programs from 26 gauge through 0.5-inch plate on select operations — with forming tolerances to ±0.005″ and weld certifications to AWS D1.1, D1.2, and D1.6 standards. From simple punched and formed brackets to complex multi-panel enclosures and welded structural assemblies — single-source capability means cutting, forming, welding, hardware insertion, and finishing all happen without leaving our facility. First Article Inspection (FAIR) reports, material certifications (MTRs), and certificates of conformance (COCs) are standard on programs that require them.
