What welding processes do you run?

MIG (GMAW) for production and structural mild steel, TIG (GTAW) for stainless, aluminum, and precision work, and stick (SMAW) for field repair and dirty steel. Most of our shop fabrication runs MIG. On-site repair and farm-equipment work usually runs stick on a portable rig.

Can you weld on-site or do I bring the piece in?

Both. We have a portable welding rig for farm equipment, structural repairs at the jobsite, and ornamental installs (gates, railings, fence sections). For larger fabrication runs and precision work, we prefer the shop where we have the right table, the right jigs, and the right ventilation.

Do you do structural steel for buildings?

Yes — beams, columns, lintels, and connection plates for residential and light-commercial. We fabricate to the engineer's stamped drawings, and any structural weld that the inspector wants to see gets witnessed. For larger buildings (over 5,000 sq ft commercial), we partner with a certified steel erector.

How thick can you weld?

On structural mild steel, we run multi-pass welds up to 1-inch plate routinely. Heavier sections (1.5-inch and up) are doable but usually drive the conversation toward a fabricator with bigger feed equipment. On stainless and aluminum, our TIG capacity is solid up to about 3/8-inch — beyond that we'd quote against a stainless shop.

Do you do equine and livestock stall fabrication?

Yes — that's a meaningful share of our welding work. Horse stall fronts, sliding doors, dutch doors, grilles, hay racks, water bucket holders, and custom stall hardware. We fabricate to the barn's exact dimensions in-shop, finish powder-coat-ready or galvanized, and install on-site as part of an equine facility build.

Can you do repair welding on farm equipment?

Yes. Cracked tractor frames, broken bucket teeth, snapped 3-point arms, equipment-trailer rebuilds — regular work for us, especially through spring and harvest seasons. We have a mobile rig for emergency field repair when the equipment can't be moved.

In-house shop + mobile rig

The welder doesn't leave. The work travels.

Most of our welding work runs through the shop — fabrication on a real table with real jigs and proper ventilation. For structural installs, field repair, ornamental installs, and farm work, the mobile rig comes to the site. Both processes are AWS-grade welds; the difference is just where we're running them.

We're unusual for a general contractor in that we own and operate the welding ourselves rather than subcontracting to a fab shop. That means structural steel for a build runs on our timeline, not a fabricator's queue. Equine stalls get built to the barn we're also constructing. Repair on a piece of farm equipment gets handled this week, not next month.

Cross-trade work is where this really pays. Foundation underpinning needs steel brackets. Retaining walls need anchor plates. Equipment-barn pads need custom bracketry. We do the digging and we do the welding, which is rarer than it should be.

What we weld

Six lines of welding work, one welder, in-house shop plus mobile rig.

Structural Steel

Beams, columns, lintels, and connection details for residential and light commercial. Fabricated to stamped drawings, inspected, and code-compliant.

Beam and column fabrication to engineer drawings
Connection plates, gussets, and base plates
Lintels for masonry and stone openings
Field welding for additions and structural retrofits

Ornamental Ironwork

Custom gates, railings, balustrades, fences, and architectural accents. Designed to the property and built to outlast the next owner.

Driveway and entry gates with hardware
Stair railings (interior and exterior)
Custom fencing — yard, pool, perimeter
Decorative panels, scrollwork, and architectural metal

Equine & Agricultural

Horse stall fronts, sliding doors, hay racks, livestock handling, and custom farm implements. Built to the actual barn, not from a catalog.

Stall fronts, dutch doors, grilles, hay racks
Custom farm implements and trailer modifications
Livestock handling equipment and chutes
Powder-coat-ready or hot-dip galvanized finishes

Equipment Repair

Cracked tractor frames, broken bucket teeth, snapped 3-point arms, equipment-trailer rebuilds. Field rig or shop, whatever the job needs.

Heavy-equipment frame and structural repair
Excavator bucket and attachment rebuilds
Trailer frame, hitch, and deck repair
Emergency field service through harvest season

Custom Fabrication

Bracketry, brackets, custom-fab parts when the off-the-shelf piece doesn't exist or doesn't fit. One-offs and short runs.

One-off bracket and mount fabrication
Mild steel, stainless, and aluminum
TIG-welded precision work for visible finish
Short-run production for trades and contractors

Welding for Excavation Crews

Cross-trade work — beam reinforcement for foundation underpinning, custom shoring brackets, structural anchors for retaining walls.

Foundation underpinning steel and brackets
Custom shoring and bracing for tight excavation
Structural anchor plates and tie-rods
Retaining-wall anchor and reinforcement fab
