Know About WPC Composite Decking: Co-extrusion Vs 1st Generation Decking

Wood-plastic composite (WPC) decking is a popular choice for flooring and decking. WPC composite decking contains renewable and recycled wood fibers and plastic material, so no tree is cut to produce the decking. It is the best substitute for timber. The decking comes in a variety of colors and design combinations. WPC composite decking is divided into two main types, Co-extrusion and 1st generation decking. This article will compare the two types of composite decking, i.e., co-extrusion vs. generation decking.

Co-extrusion vs. 1st generation decking


Before going into detail, let me briefly introduce the two types of WPC composite decking.

1st generation decking is also known as traditional composite decking or non-capped composite decking. It has a different surface texture than the co-extrusion type, which is the most economic composite decking.


Co-extrusion decking is an upgraded type of WPC composite decking that's more scratch-resistant, has practically no water absorption, and expands at a slower rate than standard composite decking.

After knowing the basic knowledge of the two types of WPC composite decking, let's compare them from the following parts.

  • Appearance features

The first generation of WPC composite decking includes a wood powder surface. The surface is exposed to severe external conditions, making it susceptible to bacteria and fungus, UV radiation erosion, dampness, and color fading. Because there is no protective coating on the surface, it is less scratch-resistant. Compared with the first generation, co-extrusion decking has a 360-degree complete coating layer, providing full protection for the core to make the decking more durable, UV stable, mold resistance, and stain resistance. The co-extrusion product's appearance features have been improved significantly over first-generation decking.


  • Service life and durability

Co-extrusion composite decking is designed from the wood-plastic composite core and engineering polymer cover protection. The covering acts as a shield to protect it from water, UV, scratch, and other risks. Due to the super-design and enhanced durability, co-extrusion decking lasts longer than the 1st generation decking.


  • UV resistance

The 1st generation composite decking has less UV resistance as compared to co-extrusion decking. Because the first generation composite decking does not have a complete water swelling and bending deformation coating, which could not be blocked the ultraviolet rays from above and could not reduce the degree of fading within a certain period of time. What's more, the customize co-extrusion composite decking can be coated with the UV layer, helping in extending the service life.


  • Stain resistance and water resistance

Co-extrusion decking has better stain resistance. When some black ink is poured on both 1st generation decking and co-extrusion decking, the ink on 1st generation may leave ink residue, and it also infiltrates into the plate. However, the co-extrusion decking can be easily cleaned with water and soap. Co-extrusion decking has a full 360-degree coating, which can provide all-around protection for the core layer. Moreover, the water absorption rate of the coating is extremely low, which effectively prevents water from entering the core layer so that the plate is not prone to color or mold.


  • Scratch resistance

The surface layer of first-generation composite decking contains wood powder. When exposed to strong UV rays and humidity for a long time, the plastic wood molecular mixture on its surface is easily degraded. It is susceptible to cracking under the pull of external forces and its own thermal expansion and contraction. On the contrary, co-extrusion of WPC composite decking has a 360-degree coating on the covers and the core layer. This antioxidant and stabilizer firmly protect the stability of the internal structure of scratch resistant composite decking. Even if it is scratched, the coating protects the surface from leaving large scratches.

  • Price

Even though with the same raw material or the production process, co-extrusion composite decking is superior to the first generation from the perfomance, which leads to its higher cost. But at the same time, the first generation decking also needs more maintenance time and cost to keep longer service time, so the co-extrusion composite decking also is the cost-competitive choice.


  • Applications

These applications are quite similar, such as backyard, swimming pools, gardens, etc. Co-extrusion is usually preferred in public places with high pedestrian traffic for its higher resistance and better look.
