Gully Covers, Duct Covers, Structural Flooring & Trench Covers
Duct Covers
Dura Slab is ideal for new constructions and replacements for duct covers but is also well suited for refurbishment applications to replace old, heavy & cumbersome traditional flooring materials and covers. The characteristics of Dura Slab make it more favourable for duct covers rather than using steel, timber or concrete systems due to its lower weight, anti-slip surface, ease of installation and absence of maintenance.
fibreglass Trench covers are low weight, max strength, anti slip top & allow easy removal for access.
Gully Covers & Trench Covers
Dura Slab ideal for gully covers & trench covers is tested to B.S. EN124. This European standard applies to gully covers, trench covers and manhole tops for vehicular and pedestrian areas. In order to reach this approval a Dura Slab panel of 74mm thickness and 1280mm span was subjected to a load equivalent to two thirds of the Class B test load, 83.3kN, and then reduced to zero.
fibreglass duct covers are High strength, low weight, anti slip. Trench, service & cable duct covers.
Structural
Dura Slab is a fibreglass structural flooring system manufactured using a unique construction technique that provides an incredible strength to weight ratio. Dura Slab structural flooring panels are manufactured by the pultruded fibreglass process to provide a composite structural flooring structure that is stiff, strong, light-weight, non-corrosive with an anti-slip walking surface.
GRP structural flooring - no lifting equipment required, low cost, anti slip & maintenance free.
Gully Covers
Gully covers are lightweight, high strength, anti slip and easily removed for access. Gully covers can easily be lifted by one to two or four man teams using standard lifting keys.
Dura Slab gully covers are lightweight, high strength composite flooring products which have been engineered for use as gully covers where incredible strength to weight is important.
Fibreglass trench covers are high strength, lightweight, easy to install, fire resistant And Include An anti slip Walking Surface.
Duct, Gully & Trench Covers
Dura Slab flooring panels are generally supplied with angular quartz grit embedded into the top surface to provide an excellent anti slip walking surface. When maintenance is required, the duct, gully and trench covers can easily be removed by a one or two man team using standard lifting keys.

Dura Slab Manufacturing Process
Glassfibre rovings and matting reinforcement |
Chemical grade resin dip bath |
Final pultruded resin glassfibre Dura Slab |
Pultruded Dura Slab Profiles are manufactured by combining various resins with pure glassfibre reinforcement. They are formed and cured in a continuous process creating a product of extraordinary strength and resilience. The resultant profile offers a combination of benefits and mechanical properties exceeding those of metal. Weighing up to 80% less than steel and concrete, Dura Slab offers equivalent performance for considerably less weight. This results in major weight savings and lower installation and servicing removal costs due to more economical transportation, handling and on site positioning. The high strength to weight ratio has particular relevance for many applications in the structural flooring, trench, gully and duct cover industries.
British Standard Test Results
The B.S. 4592 test was devised to test and assess the slip resistance of industrial type flooring intended for use in water and wet areas. A co-efficient of friction (CoF) is calculated by determining the mean angle of inclination that an operator can safely maintain when the flooring is subjected to a continuous stream of water.
