What Are Aluminium Screw Down Anti-Slip Decking Plates?

Aluminium screw down anti-slip decking plates provide a secure way to improve grip on surfaces where self-adhesive anti-slip products may not be suitable. Instead of relying on adhesive, the plates are mechanically fixed into place using screws, making them ideal for unstable or weathered substrates such as sodden timber, flaking concrete and other surfaces that are regularly exposed to moisture.

Manufactured from 1.6mm weather-resistant aluminium, each plate is fitted with a durable anti-slip surface to help reduce the risk of slips in wet and icy conditions. Available in flat plates for walkways and decking, as well as L-shaped profiles for steps and stairways, they provide a practical safety solution for residential, commercial and public environments.

Frequently Asked Questions


  • Aluminium screw down anti-slip decking plates are mechanically fixed safety plates designed to improve grip on outdoor surfaces where self-adhesive anti-slip products may not be suitable. They are commonly installed on decking, access ramps, boardwalks, steps and walkways using screws for a secure, long-lasting installation.

  • These plates are ideal for outdoor areas exposed to rain and frequent foot traffic, including timber decking, access ramps, pathways, boardwalks, marinas, garden steps, footbridges and entrance walkways. They are particularly useful on unstable or constantly damp surfaces where adhesive products may not perform as effectively.

  • Both aluminium and GRP products are designed to improve slip resistance, but they suit different applications. Aluminium screw down plates are mechanically fixed to existing surfaces and are ideal where adhesives cannot be used. GRP products are available as sheets, stair nosings, treads and decking strips, making them suitable for larger surface coverage or complete anti-slip installations. The best choice depends on your surface, environment and installation requirements.

  • Screw down plates are designed for surfaces where adhesives may struggle, such as wet timber, flaking concrete or unstable substrates. Mechanical fixings provide a secure installation without relying on adhesive bonding.

  • Yes. They are commonly fitted to timber decking, ramps, boardwalks and steps using mechanical fixings, making them an effective way to improve grip on outdoor timber surfaces.

  • Yes. The plates are manufactured from weather-resistant 1.6mm aluminium and are designed for outdoor environments, including decking, walkways, access ramps and other areas exposed to the elements.

  • Yes. Aluminium anti-slip decking plates are available in several standard sizes, with different Safety-Grip colours available to suit various environments. Custom sizes and alternative materials, including stainless steel, may also be available depending on order requirements.
