Services

What we build, what we fix, what we haul out to your place to weld back together.

Gates, Railings & Fences

Driveway gates, ranch entries, handrails, balcony rails. Built to spec, hung straight, hinges that last.

Structural Steel

Beams, posts, brackets, mezzanines. Shop-fabbed sections delivered ready to bolt up. Plans welcome — we'll work off yours or sketch it with you.

Trailer & Ag Equipment Repair

Cracked frames, busted tongues, broken disc gangs, blown-out gooseneck couplers. Bring it in or we'll come to it.

Mobile Welding

Fully equipped truck. Stick, MIG, TIG. We roll out to farms, ranches, and job sites across the valley. If it's too big to move, we'll come to it.

Hand & Guard Rail

Code-minded handrails, loading-dock guards, bollards, equipment cages. Galvanized or painted to match the site.

Hitches & Tow Work

Receiver hitches, gooseneck installs, custom bumpers, tow-point reinforcement. Built for actual loads, not weekend hauling.

What we work on

Three kinds of jobs that come through the door most weeks.

Farm & Ranch

Get the iron back in the field

Almond grower walked in with a busted disc harrow on a Tuesday morning. Pulled the bent shank, fabbed a new one out of A36, had him rolling by lunch. Gates, corral panels, equipment hitches — same idea. Down time costs money, so we don't waste yours.

Job Site

Mobile rig, anywhere in the valley

Truck-mounted welder, generator, full cutting setup, rod oven. When a contractor calls about a cracked beam splice or a railing that didn't pass inspection, we show up the same day where we can. Clean welds, clean job site.

Custom & One-Off

Built once, built right

Wine-cave gate with a working latch. Fire-pit ring with a tractor-disc lid. Steel staircase for a barn loft. Bring a sketch on a napkin — we'll take it from there. If it's metal and it has to hold up, we can build it.
