Metal Railing Fabrication Boise — Modern Steel Stairs & Architectural Metalwork
We fabricate architectural metalwork — custom railings, monostringer stairs, decorative facades, and ornamental steel — for general contractors, architects, and developers across the Treasure Valley. Every component goes from your CAD files through our CNC fabrication to ±1/16\" precision, so your install crew isn't grinding and shimming on site.
What We Fabricate
Our architectural shop handles the high-visibility steel and aluminum work that defines a building's finish. When you send us the drawings, we're building:
- Modern railing systems — cable rail, glass-clip, picket, and perforated panel configurations for multi-family, retail, office, and hospitality
- Monostringer stairs — single-carrier steel stringers with cantilevered treads, open-riser designs, and integrated LED channels
- Custom awnings and canopies — structural steel frames with integrated drainage, engineered for Idaho snow loads
- Decorative facades and screens — CNC plasma-cut perforated panels for privacy, ventilation, and brand-specific architectural accents
- ADA-compliant handrails — graspable profiles, continuous wall returns, and compliant picket spacing per IBC/ADA
How the CAD-to-Build Process Works for Architects
The biggest headache on architectural metalwork is the gap between the architect's vision and what actually gets welded. We close that gap with a direct digital-to-fabrication workflow:
- Drawing intake: We work directly from your DWG, STEP, or Revit files. No re-drawing, no interpretation layer.
- 3D fabrication modeling: We build a production model that accounts for weld shrinkage, material bend radii, and connection tolerances. If a detail won't work at full scale, you hear about it before we start cutting.
- CNC cutting and forming: Every gusset, bracket, and panel blank gets cut on our plasma table and formed on our 150-ton press brake. ±1/16\" tolerance on every piece.
- Shop assembly and finish: We pre-assemble complex connections and apply your specified finish — powder coat, galvanize, or both — before anything leaves our shop.
- Delivery and install coordination: We tag every piece with install sequence marks and coordinate delivery to match your GC's schedule. We're five minutes off I-84 in Caldwell, so same-day delivery to Boise, Meridian, and Nampa is standard.
Materials and Finishes for Idaho Conditions
Architectural steel in the Treasure Valley takes a beating — temperature swings from -10°F to 105°F, UV exposure, and road salt on lower-level railings. Our standard finish packages are built for that:
- High-performance powder coat — AAMA 2604/2605 compliant, UV-stable, available in any RAL color. Standard is satin black; custom colors are a 2-week lead time.
- Hot-dip galvanizing — 20–50 year corrosion protection. We recommend this for any exterior railing within 50 miles of the Boise River or in high-traffic commercial environments where maintenance access is limited.
- Stainless steel (304/316) — for cable rail hardware, glass clamps, and accent details where the raw metal finish is part of the design.
Scaling for Multi-Unit Projects
If you're a GC running 50+ unit apartment complexes or a developer building out a subdivision, consistency across every linear foot matters. We treat architectural railing as a manufactured product — same jigs, same tolerances, same finish batch — so the railing on building 12 looks identical to building 1. We've delivered packages of 500+ linear feet of railing for multi-family projects in Caldwell, Nampa, and Meridian with zero field rework.

Frequently Asked Questions
How much does a custom metal railing cost per linear foot?
Every project is different — cost depends on material (steel, aluminum, or stainless), railing style (cable, glass-clip, picket, or perforated panel), and finish. We quote from your architect's drawings. Send us the details and we'll get you a number.
Do you fabricate ADA-compliant handrails?
Yes. Every railing system we build meets IBC and ADA requirements — 34–38 inch handrail height, 1.5-inch diameter graspable profile, continuous returns at walls, and 1.5-inch clearance from the wall. We coordinate with your architect on picket spacing, glass panel specs, and cable tension requirements to make sure the design intent and code compliance both land.
What railing styles are popular for commercial projects in Boise?
Right now the most requested styles are cable rail systems (1/8-inch or 3/16-inch stainless cable, vertical or horizontal), glass-clip railings with 3/8-inch tempered panels, and perforated metal screens with custom CNC-cut patterns. For multi-family and mixed-use, architects are leaning toward clean-line cable and glass. Retail and hospitality tend toward perforated panels with branded or geometric patterns.
Can you match our architect's design exactly?
That's exactly how we work. We take your architect's DWG or STEP files, build a 3D fabrication model, and cut every component on CNC equipment to ±1/16" tolerance. If there are connection details that don't translate from paper to steel, we flag them before production so the design team can adjust. The goal is that what gets installed looks exactly like what got drawn.
