Built on heavy-gauge precision
Mutual Metal manufactures industrial-grade perforated metal, expanded mesh, and forge-welded bar grating. We build to tight engineering tolerances for structural, filtration, and architectural applications across North America.
Founded in Springfield, Illinois, Mutual Metal was established to bridge the gap between mass-market metal distributors and specialized project requirements. Instead of forcing projects into off-the-shelf catalog dimensions, we engineered our plant floor around flexible production runs, in-house tooling, and direct technical collaboration.
Our facility handles carbon steel, structural aluminum, and 304/316 stainless steel from raw coil to finished panels. We operate under an enquiry-based model where our engineering team reviews your drawings, tolerances, and open-area percentages before fabrication begins.
Verified tolerances
Every batch undergoes dimensional inspection against ASTM and AWS manufacturing standards.
Enquiry-based model
No generic carts or mismatched parts. We review your specifications before issuing a formal quote.
Direct plant oversight
In-house slitting, leveling, shearing, and weld inspection.
Production progression
Facility established in Springfield
Began operations with a single high-tonnage mechanical punch press focused on heavy-gauge carbon steel perforated sheets.
Expanded metal and grating lines
Added dedicated rotary slitting and heavy-duty forge-welding machinery for structural bar grating and architectural expanded mesh.
ISO 9001 & AWS certification
Standardized all in-house metallurgical inspection protocols to ISO 9001 and AWS D1.3 welding standards.
Custom specification manufacturing
Supporting structural engineers, general contractors, and filtration system builders with precision direct-quote orders.
Send your dimensional drawings or gauge requirements for direct engineering review.
