Outdoor Woodgrain Solid WPC Decking 3000mm UV Stabilized 140x20mm
140x20mm Solid WPC Decking - Fully Solid Core
This solid WPC (wood-plastic composite) decking board measures 140mm wide x 20mm thick with a standard length of 3000mm. It is built around a fully solid core with no hollow channels, giving every board a firm, stable footing and a dense, substantial feel underfoot. It is designed for outdoor decks, patios, terraces and walkways that face sun, rain and daily foot traffic.

Why a Solid 140x20mm Profile
- Solid core: no hollow chambers means a denser board with better screw-holding strength and a solid walking feel.
- 140mm width x 20mm thickness: a robust cross-section that spans standard 300-400mm joist spacing with minimal flex.
- 3000mm standard length: fewer joints per deck run; custom lengths reduce on-site cutting waste and off-cuts.
- Uniform finish: the woodgrain runs consistently from board to board, keeping large deck areas visually uniform.
Performance Highlights
- Dense solid core resists denting and point-loading better than thin-walled profiles
- Woodgrain surface masks daily scuffs, footprints and dust between cleans
- No annual staining, oiling or sealing required, unlike natural timber
- Resists rot, termites, splintering and moisture warping in wet climates
Material & Environmental Responsibility
Boards are made from natural wood fiber and recycled HDPE, reducing the use of virgin plastic and preserving timber resources. The composite contains no toxic wood preservatives, and production off-cuts are reground and recycled in-house.
Installation & Maintenance
Suitable for installation over wood, steel or composite joists using hidden clips or stainless-steel screws, with a recommended joist spacing of 300-400mm center-to-center. Clean with a broom and occasionally wash with mild soap and water; no refinishing is needed.
Quality Assurance & Testing
Each production batch is tested for water absorption, slip resistance, UV stability and dimensional tolerance before shipment. Boards are produced to CE and RoHS requirements, and third-party inspection is welcome before shipment.
