About Tri-Fab
Custom sheet metal fabrication in Salem, Ohio since 1978.
Tri-Fab has fabricated custom sheet metal in Salem, Ohio since 1978. In 2025 the shop joined The Hannon Company, a family-owned industrial group founded in 1926 — pairing 47 years of fabrication with the engineering and capital depth of a four-division group.
Tri-Fab
Build to print, from CAD through finishing.
We're a custom sheet metal job shop. Customers bring us drawings, CAD/STEP files, or sketches, and we take it from there — CAD support through finishing.
We handle one-offs, repeat orders, and production runs. Accepted designs stay on file so reorders don't start over. Every job is built to your print, and the work is managed here in Salem.
