How are decking strips installed on external steps and walkways?

Decking strips supplied by Stair Nosings UK are installed onto clean, dry, and structurally sound timber or composite boards. The substrate must be swept free of moss, algae, and debris before the strips are aligned, pre-drilled where necessary, and fastened directly across the decking profile using mechanical fixings, structural adhesive, or a combination of both.

Do decking strips comply with UK Building Regulations Part K?

Yes, decking strips from Stair Nosings UK assist in meeting the slip-resistance and safety provisions set out in UK Building Regulations Approved Document K (Protection from falling, collision and impact). They contribute towards reducing slip hazards on external stairs, ramps, and walkways by delivering a low slip potential, defined as a Pendulum Test Value (PTV) of 36 or greater in both wet and dry conditions.

What sizes and profiles are available for decking strips?

Stair Nosings UK provides decking strips in standard widths of 50mm, 90mm, and 120mm to accommodate standard grooved or smooth deck boards. Standard stock lengths include 1,000mm, 1,200mm, 1,500mm, 2,000mm, and 3,000mm, with chamfered edge profiles to minimise trip risks and custom cutting services available for specific tread dimensions.

What material options are used for decking strips?

Decking strips are primarily manufactured from pultruded glass-reinforced plastic (GRP) incorporating integrated aluminium oxide grit, or from extruded architectural-grade aluminium fitted with textured anti-slip inserts. Both material specifications offered by Stair Nosings UK provide corrosion resistance, UV stability, and long-term wear resistance in external UK environments.

Which fixing methods are recommended for securing decking strips?

Decking strips are commonly secured using countersunk stainless steel wood or composite screws (A2/Grade 304 for general exterior use, or A4/Grade 316 for coastal environments) placed into pre-drilled and countersunk holes. Stair Nosings UK also recommends applying a high-grab, external-grade hybrid polymer adhesive beneath the strip to enhance bond strength, seal against moisture ingress, and reduce movement over time.
