Cable management for transport and industrial environments
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
GRP cable management systems
Glass Reinforced Polyester (GRP) cable management systems are well suited
to aggressive environments, such as extreme weather or high temperatures.
The systems are extremely robust, considerably lighter than traditional metal
systems, and have excellent resistance against fire and corrosion resulting
in a very long life span. GRP systems have a large cable capacity, and offer
fast and flexible installation solutions, with the ability of on-site assembly
and configuration. Marshall-Tufflex can offer a wide range of GRP systems
including trays, ladders, ground ducts, troughing, accessories and fittings,
fixings and supports.
