Structural frames & platforms
Engineered structural frames, mezzanines, and equipment platforms designed for strength, stability, and safe access across warehouses, industrial plants, and commercial environments in Toronto & the GTA.

Structural steel frames, mezzanines, and elevated platforms play a critical role in optimizing commercial and industrial spaces—supporting equipment, storage loads, production processes, and safe access for personnel. These systems must be engineered for predictable load distribution, long-term rigidity, and seamless integration with the building’s structural layout.
At Weld Rich & Steel, we design and fabricate steel frames, mezzanines, equipment platforms, and catwalk systems tailored to project-specific requirements and Ontario building standards. Our process includes engineering review, steel detailing, certified fabrication, and field installation to ensure accurate alignment, reliable load-bearing capacity, and safe circulation within high-activity environments. Built from structural-grade steel profiles and precision-welded assemblies, each frame or platform delivers the strength, stability, and operational efficiency modern facilities demand.
Steel frames, mezzanines, and elevated platforms must provide safe elevated access, reliable load-bearing performance, and seamless integration into commercial and industrial operations. Below are the engineered systems we fabricate to support storage, production workflows, and elevated work areas.
Custom-engineered mezzanines designed to increase operational floor space in warehouses, industrial plants, and commercial facilities. Built as free-standing or structural systems, depending on load requirements and building layout, with integrated access components such as stairs, ladders, safety handrails, and gates.
Heavy-duty platforms fabricated for HVAC units, processing equipment, compressors, mechanical assemblies, and production machinery. Engineered for concentrated loads, vibration control, and safe maintenance access.
Narrow-span access systems used for inspections, maintenance, production oversight, and movement between elevated work areas. Fabricated with guardrails and safety features for CSA-compliant access.
Structural framing systems for multi-level platforms, mezzanine extensions, and elevated storage decks. Designed for efficient assembly, predictable load transfer, and integration with existing steel frameworks.
Hybrid platforms supported by pallet racking or structural steel—ideal for high-bay warehouses and distribution centers. Maximizes vertical space without major building modifications.
Flexible platform assemblies engineered for facilities that require periodic reconfiguration. Ideal for manufacturing, packaging, and warehouse operations with evolving floor layouts.
Materials & Styles
Steel frames, mezzanines, and elevated platforms must be fabricated using structural-grade steel profiles, engineered flooring systems, and protective finishes designed to withstand commercial and industrial loads.

| High-Performance Epoxy Systems | Yes | Yes | Enhanced resistance to chemicals and heavy-duty operational environments |
Engineering & Compliance Notes
Key considerations
Mezzanines, steel frames, and elevated platforms must be engineered to support operational loads, maintain safe circulation, and comply with commercial building and safety standards.
Proper engineering determines how the platform handles uniform loads, concentrated equipment loads, vibration, and impact forces. Frame type (free-standing, structural-supported, or rack-supported) must match operational demands and the building’s structural conditions.
All mezzanines and elevated platforms must follow applicable Ontario Building Code and CSA safety requirements—including guardrail heights, fire safety clearances, egress routes, and floor loading ratings.
Platforms must be aligned with existing equipment, mechanical systems, workflow routes, and ceiling clearances. Proper planning ensures efficient access, safe movement of personnel, and minimal disruption during installation.
Circulation elements such as stairs, ladders, catwalks, safety gates, and non-slip flooring must be selected to support everyday operations. These components play a critical role in ensuring safe, code-compliant use of the elevated system.

Steel frames, mezzanines & platforms
In many cases, yes. Projects that change floor area, load distribution, or egress routes typically require engineer-stamped drawings and a permit. We assist with engineering review and provide the documentation needed for approval.
Load ratings are engineered based on use—such as storage loads, machinery support, or personnel access. Typical commercial and industrial systems range from 60 psf to 250+ psf, depending on operational requirements.
Yes. We fabricate both fixed structural platforms and modular systems that can be expanded, reconfigured, or relocated to match evolving facility layouts.
We offer steel checker plate, open grating, diamond plate walkways, and composite decking. The right option depends on ventilation needs, slip resistance, equipment loads, and fire safety considerations.
Timeframes vary by project complexity. Standard mezzanines and platform structures typically require 1–3 weeks for fabrication, with installation scheduled to minimize disruption to ongoing operations.

Applications
Steel mezzanines, frames, and elevated platforms are widely used to expand operational space, support equipment, and improve workflow efficiency in commercial and industrial settings.
Common residential applications:
Structural frames, platforms, and mezzanine systems are engineered to support operational loads, equipment, and safe circulation within commercial and industrial facilities, in accordance with applicable Ontario and Canadian regulations. All structural steel fabrication and installation align with the Ontario Building Code (OBC), Occupational Health and Safety Act (OHSA), and relevant CSA Group standards governing structural steel design, fabrication, and erection. Welding and fabrication are performed by CWB-certified welders, ensuring structural integrity, durability, and regulatory compliance for commercial projects.
