Manufacture: ISO9001 Quality system. F.A.C.T.A. (Fabricated Access Cover Trade Association) member.
Load Rating: FACTAAn organisation that provides specifications and standards for fabricated access covers, allowing for flexibility in design and load-bearing capabilities. We are an associated member of the organisation. Class AAA - Medium Duty - GLVWGross Laden Vehicle Weight (GLVW) is the total weight of a vehicle when fully loaded. It is used as a simple way to indicate the type and size of vehicle traffic a cover is intended to withstand. 10 Tonnes / SMWLSlow Moving Wheel Load (SMWL) is the load applied by a single wheel moving slowly over the cover. It reflects the concentrated load transferred directly onto the cover surface at the point of wheel contact. 2.5 Tonnes. Full loading achieved infilled with Grade C25 concrete
