What Is Composite Decking

Composite decking is not a natural wood material, it is made of 35%HDPE(Grade A Recycled HDPE)+ 55% Wood fiber component + 10% chemical additives. The composite decking is produced from extruding machine,the extrusion process is very slow in order to keep stable quality.The composite decking boards should be heated, formed and then cooled. The composite decking boards need less maintenance than traditional wood decking, and from the appearance, composite decking is more aesthetic, more durable and sustainable.

The only available deck material was timber in a very long time. However, this all changed in the early 1990s. Composite materials began to revolutionize the world of decking. Made from combined recycled plastic and wood fiber component. Even though most decks are still built with traditional timbers, composites have become increasingly popular over the last 25 years because of their unique characteristics.

Benefits of Composite Decking

More and more people are preferring to use composite timber for their decking,as it has many benefits.To summarize,benefits is included:

Convenience of installation

Composite decking is often manufactured with a “groove” system, allowing the planks to fit together easily with hidden fixings. It decreases the installation time and gives a clear uniform look.


Unlike timber wood, composite decking does not crack, which makes it safe for bare feet and pets. Some composite products also have anti-slip function.


Composite decking is created with a finish that looks like the natural wood so you can also have the aesthetic quality of timber.

Eco friendly

WPC decking is used 95% recycled materials and have less demand from forests and plantations.

Great value for money

The installation cost is higher than that of wood decking in the short term. In the long term, however, the choice for composite decking saves a lot of money and time.


Wood decking does not always last elegant look and always need maintenance. Instead,it wears and tears over time, develops splinters and stains, and generally degrades overall as a wood material. However, durable composite decking retains its structure and look in a very long time.

More Color and Surface Pattern Choices

While wood decking can be stained in a decent amount of finishes or painted, it will need to renovate over time. Meanwhile, composite decking can be crafted in a wide assortment of colors and finishes, all of which will retain in a long time,from 5 years to 15 years according to different quality level. For composite deckings,you can also select surface pattern like wood grain or deep embossing or anti-slip grooves according to personal preference.

Types of Composite Decking

Co-extrusion & Non co-extrusion

There are currently two types of composite decking on the market,co-extrusion vs Non co-extrusion.

Non co-extrusion decking boards are always to cheaper than co-extrusion decking boards.We offer two ranges of non co-extrusion decking boards— traditional WPC decking and 3d embossed WPC decking. Although the material is resistant and hard wearing, they do not come with the same protection against staining and colour fading. This means that in the first couple of months the boards may fade in a small amount scale after being exposed to the environment.

WPC co-extrusion decking come with an exterior plastic coating, which means that the boards become highly resistant against fading and staining. The boards are easy to wipe clean and keep their colour when exposed to the environment.

Maintenance Free Decking Capped

Hollow & Solid

Composite boards can be divided into hollow and solid varieties. Hollow decking boards tend to have hollow chambers running throughout the length of the plank, while solid WPC deck boards are stronger and heavier.
