Gatic COEX offers a cost-effective alternative to traditional access systems.
COEX is a comprehensive system of single, duct and multi span access covers and frames for use in slow moving traffic situations where chequer plate, deep steel recessed or concrete slabs might otherwise be installed and a sealing facility is not required. Medium duty for C250 and heavy duty for D400 applications.
COEX offers the versatility of a galvanised steel frame combined with the rigidity and durability of ductile iron covers. This enables shallower covers to be used, which are therefore lighter than deep steel or concrete slabs. Thus offering a competitively priced long-term solution to protecting cables, pipes and underground equipment
Covers are recessed for concrete infill or solid top according to specifier preference.
Concrete infill recessed covers
Recessed covers are designed for filling with concrete as specified in BS EN 124 - C45 - 45 N/mm2 for a test cube of 150mm, or a 40N/mm2 for a test cylinder 150mm diameter x 300mm high, using a 10mm coarse aggregate.
Anti-slip surface covers
Concrete infill covers provide a non-slip surface similar to the surrounding areas. Solid top covers incorporate a raised lozenge pattern on the surface.
The components of COEX covers are manufactured from the following materials: Ductile iron components to BS EN 1563:2011 Side frames and structural steel sections (removable beams) to BS 4-1:2005.
Correctly installed, COEX covers will be non-rocking under slow moving traffic.
