GRP

Glass reinforced polymer (GRP) is an ideal material for a wide range of construction and industrial applications, from walkways and stairs to riser void flooring and access structures. It is comprised of high-strength glass fibres set in a high-performing isophthalic polyester resin that creates a material that is lightweight, strong, and highly durable. GRP is particularly suited to corrosive, wet, or electrically sensitive environments and is commonly specified where reduced lifecycle costs are important.

Why use GRP in access and safety applications? 

• Lightweight – Typically 50% lighter than steel, making handling, transportation, and installation easier, particularly in difficult-to-reach locations. 
• High Strength – Suitable for load-bearing applications such as walkways, stair treads, and riser flooring. 
• Low Carbon – A more environmentally sustainable material choice compared to steel. 
• Non-Conductive – Safe for use in environments with high-energy sources. Ideal for power distribution projects. 
• Non-Magnetic – Perfect for applications requiring non-metallic materials. 
• Chemical & Corrosion Resistant – Tested across a wide range of chemicals and temperatures, making it suitable for water, waste, and petrochemical applications. 
• Impact Resistant – GRP performs reliably in industrial and construction settings. 
• Slip Resistant – Finished with a gritted surface, preventing slips and falls on industrial walkways. 
• Fire Resistant – Tested to ASTM E84 Class A 25 or less, suitable for most industrial projects. 
• Safe On-site Fabrication – Easy, low-cost cutting with a diamond-tipped blade; no hot work permit required. 
• Low Maintenance – Offers a long, low maintenance service life. Does not rust and no painting required. 

Typical Applications and Uses 

GRP is widely used for: 

• Walkways and staircases, and riser flooring 
• Drainage gulleys and cable troughs 
• Platforms and step-overs 
• Handrails and balustrades 
• Roof access and maintenance routes 
• Chemical, water, and petrochemical environments
