Low-volume, high-complexity fabrication for critical industrial components.
Sheet and plate fabrication in stainless, carbon, aluminum, Inconel, and Hastelloy. Cutting, forming, welding, machining, and inspection performed in one facility, with special-process finishing through qualified, certified partners and heat and lot traceability on every job.
Low-volume, high-complexity fabrication in demanding materials.
Low-Volume, High-Complexity
Complex, tight-tolerance sheet and plate parts in small and medium quantities. No minimum order quantity.
Gas Turbine & Power Gen
Approved gas turbine program supplier — P28A-AL-0002 audited and compliant (GE Supplier # 102626). Insulation packs, Inconel seals, shims, and other non-rotating component families.
High-Temperature Alloys
Inconel, Hastelloy, Monel, and L605 / Haynes 25, fabricated under qualified weld procedures with heat and lot traceability.
Single-Facility Processing
Cutting, forming, welding, machining, and inspection in one building; blast, paint, and passivation in-house, with plating, anodize, and heat treatment through qualified, certified processors. No transfers between vendors during fabrication.
Traceability & Repeatability
