GRP Vertical Access Ladders and Safety Cage Systems
The Engineered Composites GRP Vertical Access Ladder System is a modular, pultruded glass reinforced plastic ladder and safety cage solution engineered for fixed access applications. The entire assembly, including side posts, rungs, hoops, cage strips, wall brackets, and top handrail, is manufactured in GRP using a fire retardant polyester and vinyl ester resin system. This eliminates the corrosion, electrical conductivity, and maintenance obligations that come with steel.
The system is supplied in safety yellow (RAL 1023) as standard and is available in eight modular configurations covering installed heights from 2,200 mm to 6,200 mm. Extension modules in 500 mm, 1,000 mm, 2,000 mm, and 3,000 mm increments allow bespoke heights beyond the standard range. All components are mechanically assembled on site using stainless steel fixings with no welding, hot works permits, or specialist tools required.
