150*25mm Rot resistant custom length traditional composite WPC decking
Product Summary
This professional layout introduces the rot resistant, custom length traditional composite WPC decking engineered for demanding municipal boardwalks, public parks, and eco-tourism trails. By deeply blending wood fibers with protective polymers, it completely eliminates fungal decay and rot. Supporting fully customized length specifications, it significantly reduces on-site cutting waste and installation time. This overview directly addresses the headaches of timber decay and high material scrap rates, delivering a highly efficient and dependable engineering solution.
Product Features
-
100% Core-to-Surface Rot Resistance
-
Unlike premium second-generation decking that relies only on an outer cap, our traditional Gen-1 WPC decking features a homogenous mix where every wood fiber is thoroughly encapsulated by polymer resin. This provides built-in rot resistant defense against continuous moisture, water pooling, and fungal attacks.
-
Precision Custom Length Optimization
-
We offer flexible custom length manufacturing tailored directly to your project’s blueprints. Contractors can order the exact lengths required for their joist spans, eliminating the massive material waste, messy on-site cutting, and excessive labor hours typical of rigid standard-size planks.
-
Uniform Mechanical Strength
-
The solid or heavy-wall structural composition ensures the material density is entirely uniform. It delivers dependable compression and flexural strength, resisting structural degradation or hollow splitting over years of public foot traffic and seasonal weathering.

How to Install
1. Subframe Spacing (Max 350mm)
Install your joists (wood or aluminum) on a level, draining foundation. Joist spacing must be a maximum of 350mm center-to-center to prevent the deck from sagging.
2. Lock the First Board
Screw Starter Clips into the edge of each joist. Slide the groove of your first WPC board firmly into these clips to lock the outer perimeter without surface screws.
3. Install Center Clips
Slide Hidden Fastening Clips into the inner groove of the board at every joist intersection and screw them down. These clips automatically create the mandatory 5mm side-to-side expansion gap. Slide the next board into place and repeat.
4. Manage End-to-End Joints (Double Joists)

FAQ
Q1: How does an uncapped WPC decking achieve premium rot resistant performance without an outer shield?
A1: The rot resistant performance comes from its homogeneous manufacturing process. During extrusion, the high-density polymers and fine wood fibers are completely cross-linked under extreme pressure. Because the polymers coat every organic particle, water and mold cannot rot the wood components inside.
Q2: What is the minimum order volume or benefit of ordering a custom length for a commercial project?
A2: Custom length optimization is ideal for large projects (typically over 500-1000 square meters). It directly improves your project's ROI by dropping material scrap rates from a typical 10% down to near 0%, saving contractors thousands in clean-up, disposal, and purchasing costs.
Q3: Will the custom length planks expand and contract more than standard sizes under the hot sun?
A3: All composite materials experience minor thermal movement based on their length. When installing longer custom length boards, our engineering guidelines specify slightly larger expansion gaps at the butt joints. This simple layout adjustment allows the rot resistant boards to shift safely without bowing.
Q4: Can this traditional composite decking be directly installed over wet soil or concrete docks?
A4: Yes. Because it is highly rot resistant and completely impervious to ground termites, it performs beautifully on low-ground patios and damp concrete docks. However, proper under-deck ventilation and correct drainage alignment must be maintained to ensure the joist foundation remains stable over time.
