View Service →Bring us a sketch, a photo or just an idea, we design, fabricate and install gates and fences that match it. We provide CAD and shop drawings, so you see the exact design before we cut steel. From clean modern horizontal slat gates to classic wrought-iron looks, we work steel, aluminum and everything between, then finish it with optional powder coating or galvanized dipping so it holds up to San Diego sun and coastal air.
One recent build: a custom ADA-accessible gate for a local American Legion post, inward-opening for mobility-impaired members with a slow-closing mechanism, designed around how the members actually use it. That's the level of thought every gate gets.
A railing has two jobs: hold weight without question, and look like it belongs in your space. We fabricate and install stair railings, balcony and deck rails, handrails and ornamental pieces in every style, modern cable-and-steel, classic scrollwork, or something only you've imagined. Every install is plumb, solid and up to code.
With 15+ years across every kind of welding, our standard for penetration, fit-up and inspection was set on jobs far less forgiving than a backyard. We bring that same discipline to beams, posts, brackets, frames and sheet metal fabrication for contractors, property managers and homeowners.
Pipe welding leaves no room for "close enough", a weld either seals and holds pressure, or it doesn't. Fifteen-plus years of pipe work across homes, businesses and boats carry into every job: proper prep, correct filler for the alloy, full-fusion passes and clean finishing.
Aluminum boat repair punishes shortcuts: contaminated metal, thin corroded sheets and stress points that fail again if the fix isn't planned right. We establish a clear, concise repair plan first, then execute it with the prep and filler discipline marine work demands. Recent work includes transom replacement, chine and centerline welding where hull sheets meet, and axle, leaf-spring and fender retrofits on trailers.
Some jobs can't come to a shop, a gate hanging off its hinge, a broken trailer on your property, structural steel already standing. Fusion is a fully mobile operation: we roll a complete welding rig to your location, California and beyond, assess onsite, and turn most jobs around in 3–5 days.
