Co-extrusion decking represents the latest innovation in composite decking technology. Its main feature is a durable outer layer bonded to the core during the manufacturing process, which provides enhanced protection against color fading, scratches and from water damage. Co-extrusion decking is not only aesthetically pleasing, but also highly durable, ensuring long-lasting performance with minimal maintenance. In addition, Co-extrusion decking is available in a wide range of colors and textures, providing a premium natural wood-like appearance, suitable for a variety of commercial and residential applications.
The protective cover refers to the protective layer wrapped around the outer layer of the deck, usually made of high-performance polymers. This protective cover can protect the composite core from UV rays and daily scratches, making the deck less prone to fading and more wear-resistant, thereby extending the service life of the deck.
The core material comes from Kosa composite materials, they are made from recycled plastic granules and recycled wood.
| Traditional WPC Decking | Co-extrusion Decking | |
|---|---|---|
 Appearance and weather resistance | Traditional WPC Decking may experience fading, discoloration, and other issues in appearance after a period of use, especially when exposed to sunlight, rain, and other environments for a long time. Its weather resistance has certain limitations. Although it can resist the erosion of some natural factors, its appearance and performance will gradually deteriorate over time. | Co-extrusion Decking has significant advantages in weather resistance. It has a special co extrusion layer on its surface, which can effectively block the damage of ultraviolet rays and greatly reduce the fading phenomenon caused by sunlight exposure. At the same time, it also has better resistance to rain, moisture, and other factors, which can maintain the bright color and good texture of the appearance for a long time, making the outdoor decking always look new, greatly improving the aesthetics and overall decorative effect of the outdoor space. |
 Wear resistance and service life | The wear resistance of Traditional WPC Decking is relatively limited. In daily situations such as pedestrian walking and furniture movement, scratches and other wear phenomena may gradually appear, which will affect its service life and appearance quality. | Due to its unique co extrusion structure, Co-extrusion Decking has higher surface hardness and stronger wear resistance. The Co-extruded layer can effectively protect the main body of the board, making it more capable of withstanding various external friction forces. This means that it is less prone to wear and tear during long-term use, and its service life can be significantly extended. Compared to traditional plastic wood panels, Co-extrusion Decking can save users the cost of replacement and maintenance, making it a more economical and durable choice. |
 Convenience of cleaning and maintenance | Traditional WPC Decking may require tedious steps during cleaning, and some common stains may be difficult to completely remove, especially after wear and tear on the surface of the board, making it easier for stains to penetrate and further increasing the difficulty of cleaning. | The surface co extrusion layer of Co-extrusion Decking is relatively smooth and less prone to stains, making it easier to clean. Even if there are stains attached, they are very easy to clean off, just use ordinary cleaning tools and cleaning agents to keep the floor clean and tidy. In terms of maintenance, it does not require frequent maintenance like traditional plastic wood panels, which can save users a lot of time and energy. |
 In Summary | Co-extrusion Decking is currently the most advantageous outdoor decking material compared to traditional WPC Decking in terms of appearance and weather resistance, wear resistance and service life, as well as cleaning and maintenance convenience. | |
1. When placing the joists, leave a distance of 3-5 mm from the building.
2.The joist needs to pre-drilling before fixing the expansion bolts.
3. The spacing between joists should be 25-30cm.
4. The spacing between expansion bolts should be 30cm to 40cm.
5. After the joist is fixed, drainage should be done to avoid factors that damage the composite decking, such as water swelling.
6. Fix the starter clips on one side of the joist.
7. Insert the composite decking into the starter clips, and install the first composite decking board.
8. Insert the clips in composite board and screw into joist (do not tighten)
9. Insert the second board into previous clips
10. Insert next row of clips securing composite board (do not tighten)
11. Fully tighten clips & screws and repeat
12. Finish the corner edging and complete the composite decking installation.
