Our products Single seal - Pressed steel coversOur pressed steel covers are available in a comprehensive range of sizes and weight loadings and a choice of steel or polypropylene frames. They are suitable for infrequent and slow moving traffic situations. Single seal is achieved by a simple labyrinth arrangement enhanced by the continuous surface of the cover at the corners. The labyrinth can be filled with grease providing a low to moderate level of resistance to gaseous and/or liquid ingress and/or egress under normal atmospheric pressure. ![]()
