WPC Decking – Wood Plastic Composite Decking is mainly made of PE and wood flour. After high-speed mixing and granulation,the wood fiber and plastic materials are extruded and formed in the models, which effectively combines the dual characteristics of PE and wood flour to made the WPC composite decking panels.

It creates the two most popular types of composite decking are capped and uncapped decking. The capped decking is made through co extrusion processing while traditional uncapped decking by compression molding, also called co extrusion decking.

The biggest difference between capped and uncapped decking is that capped decking have a additional PE production layer. So the capped composite decking also known as the upgrade for the traditional uncapped decking(1st generation composite decking) as the 2nd generation composite decking.

As for capped and uncapped composite decking, all have been designed by square hollow composite deckingcircle hollow composite decking, and solid decking models. But all the same series decking, capped composite will be more expensive than uncapped composite decking.

Because the production technology and raw materials are different, also including the additional PE production layer. Typically, the capped composite decking sales price range will be 20-50% higher than uncapped decking.

It means that if the same square meters decking projects, use the capped composite decking will cost more on the purchase of the raw materials.

However, capped composite decking owns the PE production covering additionally, which makes that the decking can last for more than 30 years while the uncapped composite decking can last around 20 years. Considering the longer durability time and post maintenance, capped composite decking will be more suitable for long term projects.

Hereby, from the costs part, for short term projects, uncapped composite decking is an economic and popular choice. For the long term decking projects, capped composite decking is more suitable.

Practicality - Uncapped decking vs Capped decking

Compared to wood decking, not matter of capped or uncapped composite decking offer uniformity in texture and consistency in quality, and be more durable, mold and slip-resistant, cooler to the touch, more sustainable, and has lower maintenance costs.

However capped composite decking, it has valuable physical advantages over uncapped composite decking.

①more fire-resistant. With a sturdy polymer blend, capped composite decking is engineered to be more fire-resistant.

②more slip resistant

No decking is entirely free of slipping risk, but as long as the boards are kept clean and well maintained, capped composite decking offers far more slip resistance as it is resistant to mold and algal growth and does not absorb water by the protection layer.
