GRP Grating Data Sheet & Installation Guide

1 GRP Moulded Grating data Sheet & Installation Guide GRP Moulded Grating data Sheet - Doc Name: GRPMG-DS/01/18 Rev: 1 2 Moulded Grating Technical data Description GRP Moulded Grating is a structural Grating product that is made by hand using fibreglass rovings and resin to offer once cured and exceptional Grating panel that has the benefit of bi-directional strength. As the Grating is made in a continuous run without the fibres ever been broken, small and medium cut outs of the Grating does not effect the panel. The Grating lends itself to many different applications from service riser Grating for open riser shaft voids, overhead walkways and gantries to heavy industrial trench covers. With its many benefits over traditional materials, GRP Moulded Grating should be the ultimate choice for the 21st Century.

2 Glassfibre rovings and Polyester resin. Below is a list of typical material properties for both components: Material Properties Glassfibre Rovings Resin Hardness (Barcol) 47 39 Tensile Strength Mpa 210 55 Modulus of Elasticity GPa (Tensile Modulus) 15 Compressive Strength MPa 18 139 Flexural Strength MPa 192 78 Interlaminate Shear Strength MPa 8 N/A Density KG/M3 (Specific Gravity) 1280 2350 Thermal Conductivity W/m C Max Operating Temp (Deg.

3 +/- 4mm width, length and diagonal (if dimension falls on a load bar, cut will either be before or after the load bar, so tolerance could be larger Depth Tolerances: +/- Mesh Pattern Tolerance: +/- (outside load bars are approx. 1mm larger) Service temperatures: -50 to 105 c Load capabilities: See enclosed list Design life: 25+ years (subject to traffic analysis). However GRP materials have been in the construction industry for 50+ years with no discernible degradation in performance General use: Standard pedestrian traffic, vehicular traffic, static items Other info: Made via heated hydraulic mould system Standards: Fire: Tested to BS 476: Part 7and met the performance requirements of Class 1. General: GRP Grating fully complies with BS 4592-6:2008 (Industrial GRP Flooring) Standard Grit Top: Most aggregates on the market use at best Quartz (Silica sand) that has a hardness of 6 7. The GRP special aggregate formula is at near diamond hardness at 9 This means that other surfaces will wear much quicker than the GRP top surface, leading to reduced slip resistance and potential slips.)

4 Of course any walking surface will wear overtime but what is important is that it maintains its maximum slip resistance for the longest amount of time. Aggregates used for walking surfaces, generally have a hardness value attributed to them and there is a scale of mineral hardness for this. For example, Iron has a hardness of 5 and Diamond has hardness of 10 (the higher the number, the harder the mineral/aggregate). In addition to the safety elements of a worn surface, there is the element of the cost associated with replacing these surfaces. Not only double cost but the cost associated with the down time of an area. We believe, DO IT RIGHT THE FIRST TIME.
