Fiberglass Walkway, Stair, and Platform Systems

Structural Fiberglass, Inc. designs, details and fabricates to your specification and/or requirements. Our Engineers design per your specific work loads, widths and heights. Units are shop assembled and shipped in maximum size sections to minimize field installation.

Design

Fiberglass Reinforced Plastic (FRP) Platforms, Stairways and Handrails are designed, engineered and custom fabricated by Structural Fiberglass, Inc. (SFI) in accordance with OSHA standards, Section 1910.25, entitled “Stairways” and Section 1910.28, entitled “Duty to have fall protection and falling object protection”.

SFI FRP Platforms, Stairways and Handrails are fabricated from fiberglass pultrusions that have a Class 1 fire retardant, with an ASTM E-84 flame spread rating of 25 or less.
