Dura Slab high quality pultruded fibreglass structural panels for various types of industrial flooring

The benefits of Dura Slab trench and gully covers and structural flooring panels.


The ability of our Dura Slab flooring to guard against deterioration from industrial chemicals and environmental factors mean that it is a logical and cost-effective alternative to carbon steel, aluminium, wood or other conventional materials. The panels will not corrode even when exposed to continuous submersion, splash, spills, fumes or gases.


The ability of Dura Slab flooring to guard against deterioration from industrial chemicals and environmental factors makes it a logical and cost-effective alternative to steel or other conventional materials. Dura Slab can resist continuous submersion, splash, spills, fumes or gases. A chemical resistant guide is available on request. Contact usnow to get yours.


Dura Slab flooring features a gritted surface that provides outstanding anti-slip protection for personnel – in wet and oily environments. The grit is embedded in the top surface of each panel prior to curing. This combination of integral construction, plus depth of the embedded grit, creates a long-lasting maximum anti-slip top surface.


The use of Dura Slab virtually eliminates maintenance. This can drastically reduce costs since painting is not required, and UV inhibitors protect against degradation from the sun which means the material does not need replacing.


Dura Slab panels weigh about one-quarter as much as steel grating. Two men can easily handle full panels, without the need for hoists, pulleys or dollies. If the panels need to be moved for cleaning, maintenance or utility access, there is less chance of back injuries. The lightweight design of the material therefore reduces installation costs.


The high glass-to-resin ratio of Dura Slab flooring provides superior strength and load-bearing characteristics. With structural integrity protected by its unique corrosion resistance capabilities, fibreglass lasts longer than traditional materials.


Composite structural materials have demonstrated a proven ability to withstand the harsh side effects of corrosive conditions better than galvanised steel. For many years, composites have been reliably used in traditionally corrosive industries such as chemical processing, plating and marine construction.


Dura Slab design procedures are entirely different from those associated with traditional materials. The prime consideration in designing with fibreglass is allowable ‘deflection’ as opposed to ultimate ‘loading’ used with steel. The inherent elasticity of reinforced plastic, permits far greater deflection than steel, without the danger of structural failure or permanent deformation.


Dura Slab is available in various resin systems, two of which meet the Class 1 flame spread rating of 25 or less, in accordance with ASTM E-84 Tunnel Test Method and to British Standard Part 7 Class 1. classification.


The construction of Dura Slab Flooring means that even after repeated impacts there is no permanent deformation. The material structure allows deflection, however, once the load is removed, the panel will return to its original shape.


Many plant operations have a need for slightly elevated flooring. Fixed or adjustable pedestals can be used for applications up to a height of 600mm.


The non-magnetic properties allow the panels to be used in sensitive installations where the inherent magnetic properties of other materials would prove unsuitable.


The non-conductive properties make Dura Slab panels ideally suited for work platforms and flooring situated in electrically hazardous locations.


Fibreglass weighs considerably less than conventional materials, and is easier and less expensive to transport, install and remove. Only simple hand tools are required for installation and removal, eliminating the need for costly equipment and labour costs associated with heavy lifting, cutting and welding equipment.


Breaking strength under a lateral force is exceptional. The uni-directional continuous fibreglass reinforcement offers numerous advantages, including rigidity, shock-resistance and no permanent deformation after overloading. These factors provide excellent mechanical strength and a generous factor of safety. Fibreglass is designed for maximum safety in intensive industrial use.


Dura Slab can be supplied with a specially formulated carbon, black surface, which will eliminate hazardous static electricity when properly grounded. It provides a safe environment in combustible areas by not allowing static sparks.


The non sparking qualities of Dura Slab are ideally suited for those installations where hydrogen or other combustible gases may be found. This prevents explosion or fire resulting from sparks produced from accidental dropping of tools onto the panel surface.


Dura Slab can provide significant savings over the use of most other materials when taking into account ‘life cycle costs’. This is due to the fact that heavy installation equipment is eliminated, there is zero maintenance plus the fact that access can be provided for servicing simply by lifting the panels.

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 Slip Resistance 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.
