Structural Steel Fabrication Caldwell Idaho — Commercial & Industrial

We fabricate structural steel for commercial and industrial projects across the Treasure Valley — building skeletons, equipment platforms, mezzanines, stair systems, and seismic-ready frames from our shop in Caldwell. Every piece goes through 3D CAD layout before it hits our 150-ton CNC press brake, so when it shows up on your job site, it fits.

What We Build

Our structural work covers the full range of commercial construction. When you send us your plans, we're cutting and forming steel for:

• Commercial building frames — column-and-beam skeletons for retail, office, and mixed-use buildings
• Equipment platforms — rated for compressor racks, HVAC units, production machinery, and heavy industrial loads
• Mezzanines — warehouse expansion platforms, 125–500 PSF, with integrated guardrails and stair access
• Stair and egress systems — IBC-compliant enclosed and open stair towers, ship ladders, and alternating tread devices
• Seismic retrofits — braced frames, moment connections, and base plate upgrades for existing structures in Seismic Design Category C

Our Process: CAD-to-Build

The biggest cost driver on any steel job is field fit-up. Welders cutting and re-welding on site burns labor hours and throws off your schedule. We eliminate that with our CAD-to-Build workflow:

• Step 1 — Drawing translation: We take your architect's DWG or STEP files and build a 3D fabrication model. If there are connection conflicts or material clashes, we flag them before we cut a single piece.
• Step 2 — CNC fabrication: Our 150-ton press brake and CNC plasma table cut every beam blank, gusset plate, and connection detail to ±1/16\" tolerance. No hand-fitting, no grinding to fit.
• Step 3 — Fit-check and finish: We assemble critical connections in the shop before delivery. Every piece gets tagged with erection marks matching your install sequence.
• Step 4 — Just-in-time delivery: We're five minutes from I-84 Exit 29. We coordinate delivery windows with your GC so steel arrives when your crew is ready to set it — not sitting on site getting in the way.

Materials and Finishes

We work in A36 carbon steel as our standard structural grade, with 6061-T6 aluminum and 304/316 stainless available for corrosion-sensitive or architectural applications. Finish options:

• Industrial powder coat — satin black standard, custom RAL colors available, UV-stable for exterior exposure
• Hot-dip galvanizing — 20–50 year corrosion protection, required for any steel within 50 miles of the Boise River or in high-moisture environments
• Primer + field coat — for projects where the GC's painting subcontractor handles the final finish on site

Compliance and Code

• IBC 2021 — all structural steel designed to current International Building Code
• AWS D1.1 — certified structural welding on every job
• ADA Standards — handrail heights, clear widths, and landing dimensions per ADA/ABA
• Seismic Design Category C — connections detailed per ASCE 7 and AISC 341 for Canyon County's 0.42g SDS

Serving the Treasure Valley

Our shop sits in the Caldwell industrial corridor off Hwy 19, five minutes from I-84. We deliver structural steel to job sites in Nampa, Meridian, Boise, Star, Middleton, and Eagle — and we've shipped fabricated packages as far as Ontario and McCall for larger projects. The advantage of working with a local Caldwell shop is simple: we can be on your site same-day if there's a fit issue, and we don't charge freight from Portland or Salt Lake.
