F1 Factory FRP Access Staircase — Built With Our Own Profiles

FRP access staircase project overview

This industrial case study documents an F1 Composite project in Chongqing, China, delivered in 2024. The supplied scope used Standard Profiles, Molded Grating, Custom Pultrusions to address the stated project constraints, with the challenge, engineered solution, measured delivery outcomes, and related product paths recorded below.

Project challenge — FRP access staircase

F1 Composite's Chongqing production base required a multi-level access staircase and intermediate platform linking the pultrusion line mezzanine to the fiber-creel area. The installation sits above the resin impregnation zone, where ambient humidity, resin vapor, and occasional chemical splash rule out painted carbon steel — historical galvanized steel stairs on this site needed re-coating every 18 months and still developed surface rust. The replacement had to be non-corroding, electrically isolating (live electrical cabinets are within 2 meters), fire-retardant to the factory's class, and installable over a 3-day shutdown window without hot work permits.

F1 Composite solution — FRP access staircase

The entire stair system was engineered and built from F1 Composite's own pultruded FRP profiles — making this an end-to-end showcase of the product line our customers buy. Stringers and landing beams use pultruded FRP I-beams and square tubes in vinyl ester resin for chemical resistance; intermediate platforms use molded FRP gratings with anti-slip gritted top surface (AS 4586 R11 rating); handrails and kick-plates are built from pultruded FRP round tube and flat bar in safety-orange UV-stabilized polyester resin for maximum visibility. All connections use 316L stainless-steel bolts through pre-drilled FRP profiles — no welding, no hot work, no cranes. The modular design allowed 4 workers to complete assembly using hand tools within the 3-day window.

Results and impact — FRP access staircase

The staircase and elevated platform have been in continuous service for 18 months with zero maintenance — no repainting, no tightening, no corrosion inspection required. Total installed weight is approximately 68% lower than the steel structure it replaced, which allowed reuse of the existing concrete pad without reinforcement. Because this is F1's own facility, we use this installation as a live reference for visiting customers — walk it, load it, inspect the connections, and see 18 months of real-world wear on profiles identical to what ships to your project.
