Popular colours for UK composite and timber decking

Some RAL colours are specified more frequently than others for UK decking installations. The DS65 is most commonly used for stair treads, thicker composite boards, and hardwood subframe applications where a longer screw is required, and the same colour range applies as for the DS50. Colour consistency across both screw lengths on the same project is straightforward as all 8 DeckingPro™ colours are available in both DS50 and DS65.

• RAL 7016 Anthracite Grey - the most widely installed composite decking colour in the UK, closely matching charcoal and dark grey boards from leading brands
• RAL 7042 Traffic Grey A - a warm mid-grey suited to stone grey and natural grey composite boards and grey-stained timber decking
• RAL 7035 Light Grey - a cool pale grey matched to light grey, silver grey and ash grey composite board variants
• RAL 8028 Terra Brown - a rich warm brown matching coffee, chocolate and mocha composite boards and warm-toned hardwood decking
• RAL 8019 Grey Brown - a deep muted brown suited to walnut and dark brown composite boards and dark hardwood timbers
• RAL 1019 Grey Beige - a warm neutral beige matched to teak and savanna-toned composite boards and natural timber decking
• RAL 1015 Light Ivory - a soft warm off-white for ivory and cream composite boards and pale timber decking
• RAL 7009 Green Grey - a muted olive-grey for sage and olive green composite boards and naturally weathered or green-stained timber decking

Frequently asked questions

What are DeckingPro™ DS65 screws used for?

DeckingPro™ DS65 screws are designed for face-fixing thicker composite and timber decking boards (25mm+), stair treads, and applications where increased thread penetration into hardwood or composite subframes is required. They are specified where the DS50 does not provide sufficient pull-out depth, including stair tread fixing, commercial decking platforms, and installations onto hardwood joists. A2 stainless steel construction makes them suitable for corrosive timber species including green oak and cedar.

What is the difference between DS50 and DS65?

The DS65 is 15mm longer than the DS50, providing greater thread engagement into the timber subframe. For standard 20 to 22mm composite or timber boards on softwood joists, the DS50 is sufficient. The DS65 is the correct specification for boards above 22mm, hardwood or composite joist systems, stair treads, and high-load areas. Both lengths are available in identical colours, so mixing them across a project produces a consistent finish throughout.
