Straight Industrial Stair Systems
Straight industrial stair systems are the most direct, cost-effective way to connect two elevations — a single uninterrupted flight from floor to platform, mezzanine, or equipment deck. Where floor space allows a clear straight run, this configuration gives the shortest travel path, the simplest structure, and the fastest installation of any stair type. Modular Solutions engineers each straight stair from aluminum stair profile with a 40mm round handrail system, setting rise and run to the elevation and available run length while holding OSHA 1910.25 stairway geometry. Serrated or grated treads provide secure footing, and integrated handrails and guardrails keep personnel protected through every transit. Because the structure bolts together rather than welds, a straight stair can be trimmed, extended, or relocated when the platform it serves is moved or rebuilt. Delivered as a bolted assembly with landing connections and gate options, a straight industrial stair replaces ladders and improvised steps with a clean, engineered access route sized precisely to your facility. For plant and safety managers, it is the workhorse stair — predictable, compliant, and adaptable to the changes every production floor goes through.
What Are Straight Industrial Stair Systems?
A straight industrial stair system is a single, uninterrupted flight of stairs connecting two levels along a straight line. It provides the most direct route between elevations and the simplest structural form, making it the standard choice for platform, mezzanine, and equipment access wherever the floor space allows a clear straight run.
Modular Solutions engineers each straight stair from aluminum stair profile with a 40mm round handrail system, setting rise, run, and width to your elevation and OSHA 1910.25 stairway criteria. Treads, handrails, guardrails, and landing connections ship as a bolted assembly that installs quickly and reconfigures as your facility changes.
Key Features
Engineered around your elevation, floor space, and facility — not a catalog template.
Direct Single-Flight Path
One uninterrupted run gives the shortest travel distance and the simplest structure — ideal wherever floor space allows a straight approach.
OSHA-Referenced Geometry
Rise, run, and tread depth engineered to align with OSHA 1910.25 stairway criteria for safe, comfortable transit.
Slip-Resistant Treads
Serrated aluminum, bar grating, or perforated treads shed debris and liquids for secure footing in industrial conditions.
Integrated Handrail System
40mm round aluminum handrails and 42-inch guardrails engineered to align with OSHA 1910.29 on open sides.
Bolted Reconfigurability
The aluminum structure trims, extends, and relocates with hand tools when the platform it serves changes — no welding.
Corrosion-Free Aluminum
Anodized aluminum will not rust or need repainting and keeps a clean professional appearance over its service life.
Common Applications
Configured for the specific access demands of your facility and environment.

Benefits
What a purpose-engineered stair system delivers on the plant floor.
- Lowest-cost stair type with the simplest structure and fastest installation.
- Shortest travel path between elevations for efficient movement.
- Replaces ladders with a stable, guarded, code-referenced route.

- Clean professional appearance for audits, customers, and staff.
Industries Served
Trusted for elevated access across demanding industrial and commercial environments.
Customization Options
Every stair is engineered to your elevation, floor space, and access requirements.
- Rise, run, and width engineered to your elevation and floor space.
- Tread materials: serrated aluminum, bar grating, or perforated plank.
- Top and intermediate landings where the run requires.
- Handrail on one or both sides with configurable returns.
- Self-closing gates at the top landing for continuous fall protection.
- Floor-anchored or freestanding base per floor condition.
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.
Design & Engineering Considerations
How our engineers approach each stair-system project.
- Elevation and run survey - We set rise, run, and total length from your floor-to-platform height and available floor space.
- Stairway geometry - Rise and tread depth are laid out to align with OSHA 1910.25 for comfortable, compliant transit.
- Load engineering - Stringers, treads, and footings are sized for concentrated foot traffic with design margins.
- Landing integration - Top and intermediate landings tie into the platform or floor with matched connections.
- Adaptability - Modular connections let the stair extend or relocate when the served structure changes.
Safety & Compliance Considerations
Stairs are engineered to align with OSHA 1910.25 stairway and 1910.29 guardrail criteria; installed compliance is verified with your safety authority.
- Stair rise, run, and tread depth engineered to align with OSHA 1910.25 stairway criteria.
- 40mm round handrails and 42-inch guardrails engineered to align with OSHA 1910.29.
- Slip-resistant treads selected for the environment, including oily and wet areas.
- Self-closing gates at top landings to maintain continuous fall protection.
- Installed compliance verified with your internal safety authority.

Frequently Asked Questions
Common questions about straight industrial stair systems design, configuration, and compliance.
What is a straight industrial stair system?
It is a single, uninterrupted flight of stairs connecting two levels along a straight line. It provides the most direct route between elevations and the simplest structure, making it the standard choice for platform, mezzanine, and equipment access wherever floor space allows a clear straight run.
When should I choose a straight stair over a switchback or L-shaped stair?
Choose a straight stair when you have clear floor space for the full run and want the shortest travel path and lowest cost. Switchback, L-shaped, and U-shaped stairs are better when floor space is limited and the flight must turn back on itself to fit the footprint.
Are straight industrial stairs OSHA compliant?
They are engineered to align with OSHA 1910.25 stairway geometry and 1910.29 handrail and guardrail criteria — including compliant rise, run, tread depth, 40mm handrails, and 42-inch guardrails. We design and document to these standards; installed certification is verified with your safety authority.
What tread materials are available?
Serrated aluminum plank, bar grating, and perforated plank — each selected for the debris, liquids, or washdown conditions at your site to maintain secure footing.
Can the stair be relocated later?
Yes. Because the aluminum structure is bolted rather than welded, a straight stair can be trimmed, extended, or relocated with hand tools when the platform it serves is moved or rebuilt.
Why aluminum instead of steel for industrial stairs?
Aluminum will not rust or need repainting, is lighter to install and relocate, and bolts together for fast, low-disruption deployment. It integrates directly with our handrail, gate, and platform accessory ecosystem.
