Outdoor Hollow WPC Composite Deck Board 139x22mm Round Hole 3000mm
139x22mm Hollow WPC Decking - Round-Hole Core
This hollow WPC (wood-plastic composite) decking board measures 139mm wide x 22mm thick with a standard length of 3000mm. The profile is built on a round-hole hollow core, which keeps each board light for handling while maintaining reliable spanning strength. It is designed for outdoor decks, patios, terraces and walkways that face sun, rain and daily foot traffic.

Why a 139x22mm Round-Hole Profile
- Round-hole core: the circular channels cut weight versus a solid board while keeping the section rigid, so boards stay easy to carry and install.
- 139mm width x 22mm thickness: a proven cross-section that spans standard 300-400mm joist spacing with minimal flex underfoot.
- 3000mm standard length: fewer joints per deck run; custom lengths reduce on-site cutting waste and off-cuts.
- Consistent surface: the embossed woodgrain runs evenly from board to board, keeping large deck areas visually uniform.
Performance Highlights
- Embossed woodgrain masks daily scuffs, footprints and dust between cleans
- Matte textured face stays comfortable underfoot in outdoor sun and rain
- 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.
