Ultrashield Pro Composite Decking Board - Grooved Edge - Anthracite Grey (3.6m x 175mm x 23mm)

Upgrade your garden with our extra-wide 175mm composite boards, featuring a top-tier Class B fire rating and a clever reversible design that lets you choose between a rustic or low-slip wood-grain finish.

We’ve also dialled up the safety with a Class B fire rating, making it a smart, compliant choice for everything from family patios to commercial terraces. To keep things solid for the long haul, NewTechWood offer a 25-year residential warranty when installed at 400mm joist centres, or a 10-year commercial warranty at 300mm centres. It’s essentially a "fit and forget" solution that stays looking brand new for decades. At a generous 175mm wide, these boards create a bold, premium finish that makes any outdoor space feel instantly larger. Because they're dual-sided, you’ve got the flexibility to choose between a "Rustic" texture or a "Low-Slip" wood grain right there on-site.

Why the UltraShield PRO stands out:

• Extra-Wide 175mm Profile: Achieve a modern, high-end look with fewer boards and a much faster installation.
• Two Looks in One: Each board is dual-sided—choose the Rustic side for a weathered charm or the Low-Slip Wood Grain for a classic, grippy surface.
• Top-Tier Fire Safety: Now upgraded to a Class B fire rating, giving you total peace of mind for both home projects and high-spec commercial builds.
• Built to Last: Fully capped to ensure your deck won't fade, stain, rot, or split, even in the unpredictable British weather.
• Fresh New Colours: Available in our three latest 2026 shades: Aged Wood, Anthracite, and Cedar.
