The Open Mesh GRP Stair Tread Grating range from IMS is designed for high-performance, permanent stair installations where corrosion resistance, slip protection, and mechanical strength are critical. Manufactured using moulded glass-reinforced polymer (GRP), these stair treads provide a reliable, maintenance-free solution for access systems in industrial, marine, and chemical environments.
Each panel incorporates a gritted anti-slip surface and a contrasting nosing to maximise visibility and underfoot traction, even in wet or contaminated areas. The Open Mesh profile ensures continuous drainage and debris clearance, preventing build-up that could compromise safety.
Technical Overview
- Thickness: Standard 38mm or as specified
- Material: Moulded GRP composite reinforced with continuous glass fibres
- Surface finish: Silicon carbide grit bonded for high slip resistance
- Nosing: High-visibility contrasting edge for compliance with BS 8300 and DDA recommendations
- Slip resistance: Independently tested to BS 7976-2
- Fire performance: Tested to ASTM E84 Class 1 and BS 476 Part 7 Class 2
- Load-bearing: Designed in accordance with BS EN ISO 14122 for access and walkway systems
- Fixings: Available pre-drilled with stainless steel clips or bolts for secure installation
Performance Characteristics
- Non-corrosive and chemically resistant: Performs in marine, chemical, and wastewater environments without degradation.
- Lightweight structure: Up to 80% lighter than steel alternatives, enabling easier manual handling and faster installation.
- Non-conductive: Safe for electrical or high-voltage areas where metal treads pose a risk.
- Low maintenance: No painting, coating, or galvanising required during service life.
- High visibility and safety compliance: Gritted nosing meets visibility contrast requirements for public access and workplace environments.
Typical Applications
- Industrial and manufacturing access stairs
- Offshore and marine platforms
- Wastewater treatment facilities
- Chemical process plants
