S.gif (1007 bytes)afety, durability and impact resistance are just some of the outstanding features that make GPI SuperTread Nosings and Treads preferred components for stairs and landings.  Commonly available in cast iron and cast aluminum, SuperTread products are also readily available in extruded aluminum carriers with a solid abrasive fill.  Maximum pedestrian safety is provided by the anti-slip walking surface and OSHA conforming barrier free installation.  SuperTread Nosings form a highly visible, defined and durable lead edge at the primary point of contact on stairs and landings.  Impact resistant, SuperTread Nosings and Treads protect exposed concrete edges that are often prone to chipping and cracking.
