Your Vision, engineered to Reality
We collaborate with architects, builders, designers, and homeowners to turn stair concepts into statement-making focal points. From sleek, minimal staircases with open risers to industrial steel staircases for high-traffic environments, every project is tailored to match your functional needs and design goals. Our team helps navigate style choices, site requirements, and code considerations, so your stair system is as safe as it is striking.
Custom Metal Stair Styles We Build
We design and fabricate a wide range of custom stair configurations for both residential and commercial applications. Every stair is cut, welded, and finished by hand using high-quality materials that ensure long-term durability and timeless style.
Floating Steel Stairs
Create an open, modern look with cantilevered treads and hidden stringers. Ideal for residential interiors or commercial lobbies where architectural detail matters.Mono Stringer Stairs
A single steel spine supports each tread, offering minimalist design with robust performance. Often used in contemporary homes and loft-style spaces.Double Stringer Stairs
Two visible side stringers give the stairs extra support and symmetry — great for wider staircases, commercial installations, or multi-unit buildings.Spiral or Curved Metal Stairs (by request)
Compact and elegant, these staircases add a dramatic, architectural twist. Perfect for tight areas or bold design statements.Steel Stair Stringers
We offer custom-fabricated stringers as standalone components or as part of full stair packages. Designed for builders needing reliable structural elements for stair installs.Floating Stair Kits
Pre-engineered kits include stringers, brackets, and mounting solutions for DIY or contractor installation. Clean, modern, and made to fit your space.
We also offer custom railings, wood or metal tread options, and finishes ranging from blackened steel to powder coat, raw industrial, or Corten rusted finishes, ensuring your stairs reflect your unique style.

Our Custom Process for Metal Stairs-From Layout to Lift-Off
1. Design Consultation:
We begin by reviewing your layout, elevation specs, and architectural style. Whether it’s a new build or a remodel, we gather all necessary details — dimensions, mounting surfaces, and material preferences — to ensure a seamless fit.
2. Design & Quote:
– Our team then produces a conceptual design, complete with options for materials, finishes, tread spacing, and handrail styles. You’ll receive a detailed, transparent quote that includes everything — from fabrication to shipping or installation.
3. Fabrication:
Once approved, we cut, weld, and finish your stair components in our Idaho fabrication shop. Each piece is handcrafted with precision using industrial-grade steel or aluminum, and customized to your exact specs.
4. Delivery or Installation:
We offer local installation throughout Boise, Meridian, Eagle, and the Treasure Valley, or nationwide shipping with carefully crated and labeled components, ready for install by your GC or team.
