OSHA-Compliant Stair Systems
OSHA-compliant stair systems are engineered from the ground up to align with the federal standards that govern fixed industrial stairs — OSHA 1910.25 for stairway geometry and 1910.29 for handrails and guardrails. Non-compliant stairs are among the most common citations in general industry, and they expose both personnel and the business to real risk. Every Modular Solutions stair is designed around these criteria: consistent rise and tread depth within code limits, compliant stair angle, uniform landings at required intervals, 40mm round handrails at the correct height, and 42-inch guardrails with mid-rails and toe boards on open sides. We build each stair from aluminum stair profile as a bolted assembly, delivering documentation that shows how the geometry and guarding align with the standards for your installation. While final certification for the installed condition rests with your internal safety authority, our designs give your team a defensible, standards-referenced starting point — and the same modular structure reconfigures as your facility changes without compromising compliance. For any facility facing an audit, a citation, or simply a commitment to worker safety, compliance-first stair design removes guesswork from elevated access.
What Are OSHA-Compliant Stair Systems?
OSHA-compliant stair systems are fixed industrial stairs engineered to align with the federal standards that govern them — OSHA 1910.25 for stairway geometry (rise, run, angle, landings) and 1910.29 for handrails and guardrails. They are designed compliance-first, so elevated access meets recognized safety criteria rather than being retrofitted for it later.
Modular Solutions builds each stair from aluminum stair profile with a 40mm round handrail system as a bolted assembly, delivering documentation showing how the geometry and guarding align with the standards. Final certification for the installed condition is confirmed with your safety authority, and the modular structure reconfigures without compromising compliance.
Key Features

Why Choose Modular Aluminum Stair Construction
Modular aluminum stair systems bolt together without welding and reconfigure without cutting — giving you a purpose-engineered stair today that adapts through every platform change, layout revision, and facility expansion without scrapping steel. Built from aluminum stair profile with an integrated 40mm round handrail system, the structure will not rust, flake, or require repainting, presents a clean professional appearance, and ties directly into our platform, guarding, gate, and handrail ecosystem. It is lighter to install with minimal floor disruption, faster to relocate, and engineered and manufactured in-house in Auburn Hills, MI so the stair fits your elevation and floor space exactly rather than forcing your facility to fit a catalog.

Frequently Asked Questions
Common questions about osha compliant stair systems design, configuration, and compliance.
What makes a stair OSHA compliant?
A compliant fixed industrial stair meets OSHA 1910.25 for stairway geometry — consistent rise and tread depth within limits, compliant angle, and landings at required intervals — and OSHA 1910.29 for handrails and guardrails, including 40mm handrails at the correct height and 42-inch guardrails with mid-rails and toe boards on open sides.
Do you certify that the stair is OSHA compliant?
We engineer and document each stair to align with OSHA 1910.25 and 1910.29 and provide a design package showing how the geometry and guarding reference the standards. Final certification for the installed condition rests with your internal safety authority, which we support with our documentation.
Which OSHA standards apply to industrial stairs?
OSHA 1910.25 covers stairway design (rise, run, angle, landings, width), and OSHA 1910.29 covers fall protection systems including handrails and guardrails. Together they define compliant fixed industrial stairs in general industry.
Can you replace our non-compliant stairs?
Yes. We frequently engineer compliant replacements for non-conforming or improvised stairs identified in audits or citations, matching the new stair to your elevation, layout, and traffic while meeting the standards.
Does compliance survive facility changes?
Yes. The bolted aluminum structure reconfigures and relocates with hand tools, and we re-reference the standards for the new condition so the stair stays compliant as your facility changes.
What documentation do you provide?
We provide design drawings and notes showing how the stair geometry and guarding align with OSHA 1910.25 and 1910.29 for your installation — supporting your safety authority's certification.
