Safety-Railed Catwalks
Safety-railed catwalks put fall protection first — elevated walkways engineered from the ground up around continuous guardrails, toe boards, and self-closing gates to keep personnel protected on every span. Elevated walking-working surfaces are a leading source of fall citations and injuries, and a catwalk is only as safe as its guarding. Safety-railed catwalks are built so the fall-protection system is integral to the structure, not an add-on: 42-inch guardrails with mid-rails, 4-inch toe boards on every open edge, self-closing gates at all access points, and slip-resistant decking, all engineered to align with OSHA 1910.28 and 1910.29 criteria. Modular Solutions builds each safety-railed catwalk from T-slot aluminum, routing the walkway to your access needs while the guarding envelope stays continuous around every edge, opening, and transition. Because the structure bolts together, it installs around existing equipment and reconfigures without compromising the guarding. For facilities focused on fall-protection compliance and worker safety on elevated routes, safety-railed catwalks deliver a walkway where guarding is engineered in from the first span to the last.
What Are Safety-Railed Catwalks?
A safety-railed catwalk is an elevated walkway engineered around its fall-protection system — continuous 42-inch guardrails, mid-rails, 4-inch toe boards, self-closing gates, and slip-resistant decking on every span and opening. The guarding is integral to the structure, aligned to OSHA 1910.28 and 1910.29 criteria, rather than added on afterward.

Why Choose Modular Aluminum T-Slot Construction
Modular aluminum T-slot catwalks and walkways bolt together without welding and reconfigure without cutting — giving you a purpose-engineered elevated route today that adapts through every equipment change, line re-lay, and facility expansion without scrapping steel. Built from 45 Series T-slot extrusion 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 stair, platform, crossover, and guarding ecosystem. Open grating decking sheds debris and lets light through to the floor below, lightweight aluminum eases installation and reduces imposed loads, and every walkway is engineered and manufactured in-house in Auburn Hills, MI so the route fits your facility exactly rather than forcing your operation to fit a catalog.
Design & Engineering Considerations
How our engineers approach each catwalk and crossover project.
- Fall-protection first - We design the guarding envelope as the primary requirement, then route the walkway within it.
- Continuous guarding - Rails, toe boards, and gates are laid out to keep protection unbroken through openings and transitions.
- Standards alignment - The design references OSHA 1910.28 and 1910.29 heights, spacing, and criteria.
- Structural design - Supports and decking are sized for pedestrian loads with design margins.
- Adaptability - Modular connections let the catwalk reconfigure without breaking the guarding envelope.
Safety & Compliance Considerations
Every structure is engineered to align with OSHA 1910.28 walking-working-surface and 1910.29 guardrail criteria; installed compliance is verified with your safety authority.
- Continuous 42-inch guardrails, mid-rails, and 4-inch toe boards engineered to align with OSHA 1910.29 on every edge.
- Self-closing gates at all access points to keep the guarding envelope unbroken.
- Walking-working-surface criteria referenced to OSHA 1910.28.
- Slip-resistant decking selected for the environment.
- Optional fall-arrest anchor points; installed compliance verified with your safety authority.

Frequently Asked Questions
Common questions about safety-railed catwalks design, configuration, and compliance.
What is a safety-railed catwalk?
It is an elevated walkway engineered around its fall-protection system — continuous 42-inch guardrails, mid-rails, 4-inch toe boards, self-closing gates, and slip-resistant decking on every span and opening. The guarding is integral to the structure, aligned to OSHA 1910.28 and 1910.29.
How is this different from a standard catwalk?
All our catwalks include guarding, but safety-railed catwalks are designed fall-protection-first: the continuous guarding envelope is the primary requirement, maintained unbroken through every opening and transition, which is ideal for high-risk spans and citation response.
Which OSHA standards apply?
OSHA 1910.28 covers walking-working surfaces and duty to provide fall protection, and 1910.29 covers the fall-protection systems including guardrails and toe boards. We engineer and document to both.
Can you add fall-arrest anchors?
Yes. Where guarding alone does not cover a task, we add fall-arrest anchor points into the structure to support personal fall-arrest systems.
Can it replace our non-compliant walkway?
Yes. We frequently engineer safety-railed catwalks to replace unguarded or non-compliant elevated walkways identified in audits or citations, matching the route while making the guarding continuous.
Does the guarding stay continuous when reconfigured?
Yes. The bolted T-slot structure reconfigures with hand tools, and we maintain the continuous guarding envelope through any changes — verified with your safety authority.
