A staircase is structural, functional and highly visible at the same time. Metal stairs can solve problems that wood cannot, such as tight footprints, outdoor exposure and long spans, and can also become the most memorable feature in a space.
We fabricate straight stairs, stairs with landings, spiral staircases and exterior steps in steel, with treads in steel plate, grating, wood or other surfaces depending on location. Railings and handrails are fabricated to match.
This is a project where planning counts. Rise, run, headroom, attachment points and loading all need to be reviewed together. If you only need a railing on an existing stair, see railings and handrails.
Stairs are structural and life-safety elements. Project requirements, design coordination, safety considerations, loading and applicable approvals are reviewed for the specific job. We do not claim engineering credentials, and some projects may require separate design review.
Where it applies
Metal Stairs & Spiral Staircases for homes and businesses
Residential and commercial applications
Residential
- Spiral staircases to lofts, roof decks or mezzanines
- Exterior stairs to raised patios, decks or second-floor entries
- Basement and cellar access stairs
- Statement interior staircases with wood or steel treads
Commercial
- Mezzanine access in warehouses and shops
- Exterior fire escape style and service stairs
- Rooftop access stairs
- Platforms and steps for equipment access
Why customers call
Why customers choose metal stairs
- Tight footprints
- Spiral designs reach another level in a small footprint where a straight stair will not fit.
- Outdoor durability
- Steel stairs with proper finishing handle weather better than many alternatives.
- Replacing worn or unsafe steps
- Rotted wood or corroded steel stairs can be replaced with a new structure.
- A design feature
- Open risers, floating treads and slim stringers can define a space.
Design, materials and finish
Types, materials and finishes
Configuration
Straight, L-shaped, U-shaped, spiral or curved stairs, with or without intermediate landings.
Treads
Steel plate, perforated or bar grating for exterior use, or wood and other surfaces interior.
Stringers and structure
Single center stringers, double stringers or fabricated frames, sized to span and load.
Finish
Powder coat or paint for exterior, or clear coat and darkened finishes for interior steel.
Spiral versus straight stairs
Spiral stairs save floor area but are steeper and can be harder for carrying furniture or for frequent daily use by many people. Straight stairs with landings are easier to climb but need more room. If the stair is a primary route between floors, tell us. If it is occasional access to a loft or roof deck, a spiral is often a perfect fit. We will help you weigh these.
How the work goes
A realistic project process
Project process
Step 1
Discuss the space and purpose
Call to describe floor-to-floor height, available footprint, indoor or outdoor and who will use the stair.
Step 2
Review requirements and measurements
Rise, run, headroom, attachment and loading requirements are reviewed for the job, including any approval needs.
Step 3
Fabricate and finish in the workshop
Stringers, treads and railings are fabricated, welded and finished, often in sections for transport.
Step 4
Install and secure
The stair is set, anchored and aligned, and railings are completed.
Scope and pricing
What affects the scope and cost
Every project is different, so pricing depends on the details. These are the factors that shape the work.
- Floor-to-floor height and stair configuration
- Tread and stringer materials
- Railing design
- Structural and anchoring requirements
- Site access for delivery and installation
- Finish and any required design review
Questions
Metal Stairs & Spiral Staircases: common questions
How much space does a spiral staircase need?
Spirals come in a range of diameters. The right size depends on floor height and usage. Share your space dimensions when you call.
Can metal stairs be built for outdoors?
Yes. Exterior stairs use materials and finishes chosen for weather exposure and traction.
Do you handle permits and engineering?
Requirements vary by project and jurisdiction. We review them for each job, and some projects may require separate design review. We do not claim engineering credentials.
Can you replace a rotting wooden exterior stair with metal?
Yes, that is a common project. We review the connection points and what the new stair will bear on.
