140*25 Deep embossing dimensionally stable Co-extruded WPC decking
Product Summary
This ultra-premium layout introduces the deep embossing, dimensionally stable Co-extruded WPC decking engineered for high-end architectural terraces, luxury pool surrounds, and commercial walkways. Utilizing advanced 3D micro-engraving technology on its dense polymer shell, it replicates the rich, matte, and warm tactile quality of natural timber. Simultaneously, formulated with a highly crystalline reinforced composite core, it achieves an incredibly low coefficient of thermal expansion. This overview directly eliminates common industry headaches like cheap plastic appearances and climate-induced warping, delivering a visually stunning and structurally flawless flooring solution.
Product Features
-
Ultra-Realistic Deep Embossing Aesthetics
-
The outer polymer armor features a high-definition deep embossing grain that is mechanically pressed at high temperatures. This premium finish creates random, non-repeating natural micro-textures that scattering light reflection, completely eliminating the cold "shiny synthetic look" and delivering the timeless elegance of raw forest hardwoods.
-
Engineered High Dimensionally Stable Structure
-
Our Co-extruded WPC decking is infused with an advanced internal core formulation that stabilizes the product at a molecular level. It is highly dimensionally stable, exhibiting minimal linear thermal expansion and contraction, which means your deck will remain perfectly straight, flat, and securely aligned through severe seasonal temperature swings.
-
Long-Term Textured Mechanical Durability
-
Because the deep embossing is forged directly into a high-density, modified engineering plastic shell, the tactile grain possesses incredible wear resistance. It resists being worn smooth or flattened by heavy public foot traffic, high heels, or frequent washing, maintaining its rustic beauty over its 25-30+ year lifespan.

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)

5. Perimeter Wall Gap & Fascia

FAQ
Q1: How does the deep embossing on a Co-extruded deck avoid looking like cheap plastic?
A1: Cheap composites use a shallow, repeating hot-stamp that reflects light, making them look shiny and synthetic. Our deep embossing technology uses a specialized matte-shield multi-tonal finish with deep, varying grain depths. This scatters natural light just like genuine timber, giving it a premium, organic texture.
Q2: Why is a dimensionally stable profile so critical for large-scale outdoor commercial flooring?
A2: In large public spaces, thermal movement can create massive cumulative forces. If a material expands too much, boards will buckle, pop their clips, or warp. A dimensionally stable Co-extruded deck guarantees that expansion forces are tightly controlled, preventing dangerous trip hazards and maintaining straight, clean engineering lines.
Q3: Will the deep embossing grooves trap dirt and make the Co-extruded deck hard to clean?
A3: Not at all. Unlike 1st generation wood-composites where dirt gets ground into the exposed raw wood fibers, our Co-extruded shield is entirely non-porous. Even though the embossing is deep and realistic, any trapped dust or mud stays resting loosely on top of the plastic shield and can be effortlessly flushed out with a garden hose.
Q4: How does a dimensionally stable deck behave during a rapid frost or ice-melting cycle?
A4: Excellent. Materials fracture during freeze-thaw cycles because absorbed water expands into ice. Our dimensionally stable Co-extruded outer cap provides 360-degree waterproof protection with zero water absorption. Because no water can enter the inner core, the boards remain completely structurally stable and secure during sudden frost cycles.
