Anti-Slip Strips for Smooth & Flat Timber Decking

RetroGrip® Tread is a surface-mounted aluminium anti-slip strip designed for smooth or flat timber decking that cannot accept standard RetroGrip® decking inserts. It improves grip on slippery decking, timber walkways, ramps, bridges, platforms and access routes.

It is the ideal solution where standard RetroGrip® decking inserts cannot be used because the decking is smooth rather than grooved, or where a wider visible non-slip strip is required. It is commonly specified for smooth decking boards, timber boardwalks, access ramps and commercial walkways.

Important: RetroGrip® Tread can be used on steps in some situations, but for stair edges and step nosings, RetroGrip® Stair Nosing is usually the more suitable product.
