Steel built right. Since 1972.
From structural steel and stairs to 5-axis waterjet parts and stainless process skids, Martin's Metal Fabrication delivers exceptional value to builders and manufacturers across Northern California.
One shop. Every kind of metal work.
Large-scale production or a one-of-a-kind custom piece — our in-house capabilities cover the job from first cut to final install.

Structural Steel Fabrication
Beams, columns, moment frames and complete steel packages — fabricated in our shop and erected by our own crews.

Stairs, Railings & Misc. Metals
Code-compliant egress stairs, spiral stairs, guardrails and handrails for schools, commercial and residential projects.

Sheet Metal Fabrication
Precision shearing, forming and rolling in steel, stainless and aluminum — one-offs through production runs.

Laser, Plasma & 5-Axis Waterjet
Three cutting technologies under one roof, including 5-axis waterjet and 5-axis plasma for bevels and thick plate.

CNC Machining
Precision machined components, flanges and fixtures to support fabrication or stand on their own.

Custom Job Shop & Process Skids
Stainless process skids, conveyor systems and industrial equipment built to spec for manufacturers and processors.

Canopies, Trellis & Gates
Architectural steel that makes an entrance — from winery gates in Napa to drive-thru canopies.

Custom Art & Signage
Our Art Division brings sculptures, feature walls and signage to life with the same precision as our structural work.
