features and bene ts
easy installation and Modi cation
Lightweight and robust, with interlocking and self adjusting couplings to assist
assembly, GRP systems allow on-site installation and modification without the need
for special tools, de-burring, painting or earth bonding.
Low Maintenance
GRP products are corrosion resistant and can withstand extreme weather conditions,
salt and most chemicals without the need for painting and protective coatings.
fire security
Effective at temperatures between -80°C to +130°C, GRP has a low conductivity and is
a self extinguishing, Zero Halogen material that is low smoke classified.
insulating
Excellent insulating material resulting in high performance cable protection with no
earthing required.
Mechanical Properties
Loading characteristics in accordance with IEC 61537. For deflection values,
coefficient of safety and load calculations refer to page 14.
GrP Vs steel
GRP is 40% lighter
Completely corrosion resistant. No rusting
even when in contact with salt spray, H25,
acid built up from exhaust gases, or brake
dust along roads and railways
Fast installation with fewer fasteners
Easy to cut and drill
Slow rate of heat transfer
Earthing not required
Antimagnetic and therefore resistant to
electromagnetic pulses
Lower life cycle cost
