What Are Custom Steel Stairs & Ramps?
Definition: Custom steel stairs and ramps are access structures designed and built for a specific location, height, and use, using steel scaffolding, steel framing, or fabricated steel components. They provide safe pedestrian access between levels, over obstacles, or into buildings and work areas, and can be engineered to meet construction safety, building code, and accessibility requirements depending on whether they serve workers, the public, or both.
Standard stair units and ramps do not fit every situation. Sites with unusual heights, tight footprints, sloped or uneven ground, multiple landings, or long spans often need a custom solution. Steel is the material of choice when the structure must carry heavy loads, handle high traffic, remain in place for long periods, or resist impact and abuse — such as at busy construction entrances, industrial facilities, and temporary public access routes.
Custom steel access can be built from steel systems scaffolding with stair units and deck components, assembled from modular steel stair and ramp systems, or fabricated entirely to the design. Each project typically starts with a site survey and engineered drawings that address loading, guardrails and handrails, slip resistance, and any code or accessibility requirements. Through Scaffold Exchange, you can find companies across the U.S. that design and build custom steel stairs and ramps and compare their capabilities and availability.
Common Custom Steel Access Structures
Custom steel access projects combine several structure types, each designed for its location and use.
Stairs & Stair Towers
Straight-run, switchback, and multi-flight stairs and stair towers built to the exact rise, footprint, and landing locations of the site.
Ramps
Pedestrian and accessible ramps with compliant slopes, landings, and handrails for wheelchairs, carts, and equipment.
Landings & Platforms
Intermediate and top landings, work platforms, and entry decks that connect stairs and ramps to doors, trailers, and elevated levels.
Bridges & Crossovers
Pedestrian bridges and crossovers that span trenches, excavations, pipes, and obstacles with guarded walkways.
Guardrails & Handrails
Guardrails, handrails, and infill sized for worker or public use, with slip-resistant treads and decking throughout.
Common Applications & Project Types
Custom steel stairs and ramps are used across construction, industrial, institutional, and public projects throughout the United States wherever standard access products will not fit.
Construction site entrances and building access
Temporary egress during renovations and closures
Excavation and foundation access
Industrial plant and equipment access
Temporary ADA access to schools, offices, and storefronts
Modular building and trailer entries
Event venues and public gathering spaces
Long-term temporary access in high-traffic areas
How Custom Steel Access Compares to Related Project Types
Custom steel stairs and ramps are one of several ways to provide safe access. Here is how they compare to related project types and which situations each suits best.
Lightweight custom access
- Lighter and easier to handle
- Naturally corrosion resistant
- Lower load capacity than steel
- Best for moderate traffic and fast installs
Accessibility-focused access
- Designed to ADA accessibility standards
- Compliant slopes, landings, and handrails
- Serves wheelchair users and the public
- Best for public and accessible routes
Heavy-duty custom access
- Designed to exact site conditions
- Highest load and traffic capacity
- Durable for long-term temporary use
- Best for heavy use and demanding sites
Building code compliant access
- Designed to International Building Code
- Riser, tread, and guard requirements
- Suited to permitted public egress
- Best where building officials require IBC
Adjustable temporary stairs
- Adjusts to changing heights
- Fast to set and relocate
- Standard sizes rather than custom
- Best for construction access between levels

OSHA Compliance & Safety Standards
Stairs used by workers on U.S. construction sites are governed by OSHA 29 CFR 1926 Subpart X, Stairways and Ladders, with specific requirements in 29 CFR 1926.1052. Structures used by the public may also need to meet the International Building Code as adopted locally, and accessible routes must meet the 2010 ADA Standards for Accessible Design. Custom designs should identify which requirements apply before engineering begins.
- Construction stairs installed between 30 and 50 degrees from horizontal
- Uniform riser heights and tread depths throughout each flight
- Handrails and stair rails on stairs and unprotected sides
- Accessible ramps no steeper than 1:12 with level landings
- Slip-resistant treads, decks, and ramp surfaces
- Engineered for the anticipated pedestrian and equipment loads
