British Standard Compliant
Dura Slab can be BS EN 124 approved. This European standard applies to
gully tops and manhole tops for vehicular and pedestrian areas. In order
to reach this approval a Dura Slab panel is subjected to a repeated load
as per BS EN 124 standards. The test is continued to evaluate absolute
failure
level.

Dura Slab Load Capacities
All data is theoretical. A safety factor of 2.5 has been used to determine which BS EN 124 Classification can be met at each span.

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.
