WPC Decking 150x25mm Durable Composite Deck Boards Low Maintenance Eco Friendly
Premium 150x25mm WPC decking designed for high-traffic outdoor projects. Engineered from eco-friendly wood-plastic composite, these durable deck boards offer a high-density, low-maintenance alternative to traditional timber without splitting or warping. Perfect for commercial and residential patios, gardens, and landscaping looking for long-lasting weather resistance.
About this Product
- Heavy-Duty 150x25mm Profile: Engineered with a robust, optimized cross-section that maximizes weight distribution and load-bearing capacity, reducing joist span requirements and saving structural installation costs.
- Ultra-Low Maintenance: Eliminates the need for sanding, staining, oiling, or painting. The high-density composite matrix prevents water absorption, completely eliminating common timber failures like warping, splitting, rot, and decay.
- Architectural Seamless Fit: Tailored for modern, clean-lined outdoor layouts. The precise profile design ensures uniform alignment and a sleek, continuous surface effect without wide, unsightly gaps.
- Eco-Friendly Circular Materials: Manufactured using recycled wood fibers and premium polymers. This sustainable loop lowers your project's carbon footprint while meeting strict international green building import standards.
- Weatherproof & Fade Resistant: Enhanced with specialized UV inhibitors to maintain color integrity over years of intense sun exposure, making it ideal for open patios, gardens, and poolside projects.

How to Install
Step 1: Substructure Preparation
Ensure the ground is flat, solid, and has a slight slope (1-2%) for proper water drainage. Secure the joists (keels) to the concrete base using expansion screws. Joist Span Requirement: For our heavy-duty 150x25mm profile, the center-to-center distance between joists must be 300mm to 350mm maximum to prevent bouncing and handle high loads.
Step 2: Fixing the Starter Clips
Install the starter clips or first row of fasteners at the edge of the joists. Slide the first 150x25mm WPC deck board into position against these clips.
Step 3: Securing with Hidden Fasteners
Insert our specialized plastic or stainless steel hidden clips into the side groove of the board where it intersects with each joist. Fasten the screws into the joists through the clip center. Position the next WPC board, pushing it firmly into the exposed side of the clips.
Step 4: Managing Expansion Gaps
WPC materials expand and contract slightly with temperature fluctuations. Refer to the diagram above to leave appropriate spacing:
- Side-by-Side Gap (between two boards): 6-7mm (automatically set by our clips)
- End-to-End Gap (at butt joints): 10mm expansion space must be cleared
- Dual-Keel Rule: Where two board ends meet, you must install two parallel pieces of keels so each board end is independently supported by its own clip
Step 5: Fascia & Edge Finishing
Once all decking boards are locked into place, cover the exposed raw outer framework using our matching L-shape side cover (fascia trim). Fix it securely along the perimeter using color-matched countersunk screws.

Frequently Asked Questions
Q1: What is the loading capacity of a 40'HQ container for this 150x25mm profile?
We optimize packaging strictly for volume imports. Depending on the customized length (e.g., 2.2m, 2.9m, or 4.0m) and the pallet configurations, a standard 40'HQ container can hold up to 950 to 1,000 square meters of our 150x25mm WPC decking, maximizing your shipping cost-efficiency per square meter.
Q2: Does your WPC decking require specialized tools for installation?
No heavy specialized equipment is required. You can process our 150x25mm WPC boards using standard woodworking tools (miter saws, hand drills, and countersink bits). Our hidden fastening clip system automatically sets the 6-7mm side-by-side gap, significantly accelerating the on-site construction pace for contractors.
Q3: How do you control batch-to-batch color consistency for large projects?
Color consistency is a key indicator of a source manufacturer. We use localized digital colorimetry during the raw material blending and extrusion phases, strictly maintaining the color tolerance at Delta E less than 0.5. This industrial-grade tracking ensures a seamless architectural look across multiple batches without noticeable shifts.
Q4: Does this product meet commercial building code fire ratings?
Yes. Our architectural-grade 150x25mm WPC profile is engineered with advanced flame-retardant additives, achieving a certified B1 Class fire rating (under EN 13501-1 standards). This qualifies the material for strict high-traffic commercial tenders, including resort boardwalks, public parks, and outdoor restaurant platforms.
Q5: Will the 150x25mm decking warp or rot in high-humidity or coastal areas?
Not at all. With a water absorption rate under 1.0% (24h full immersion testing under EN 317), our high-density composite matrix blocks moisture from entering the core. Unlike traditional timber, it is completely immune to rotting, warping, splitting, and marine borers, making it ideal for poolside and waterfront applications.
