What is capped composite decking boards?

Wednesday, April 06, 2022

Currently, capped composite decking boards materials are popular among composite decking suppliers. This is because they not only have a look that mimics wood. But are also very durable and long-lasting, requiring little maintenance. Capped composite decking consists of traditional composite wood and a durable polymer protective shell. Unlike pressure-treated wood decking, covered composite decking will not chip, crack or rot.

Capped composite decking will not fall victim to pests and does not require sanding, staining, or refinishing. For everyday use, all you need is an occasional soapy wash to make it look as good as new. In addition, decking composite is very resistant to staining and fading. So you can maintain its beautiful appearance with minimal maintenance.

Features of capped composite decking boards

Covered composite decking has come a long way from the early days of uncovered composite decking. Today, we have added a protective shell of polymer to the composite. This PVC casing provides additional protection with a higher level of water and mildew resistance. Also, this capping contains UV inhibitors that provide additional strength and resilience elements.

Of course, when we say capping, we don’t mean something that is added after the composite decking is made. Rather, the cap is bonded to the core during the manufacturing process of the composite deck.

How is capped composite decking made?

The production of capped composite decking requires the use of a co-extrusion process. The co-extrusion process produces a strong, flexible composite deck with a long-lasting appearance. In the production of capped composite decking. Wood and polyethylene polymer are carefully mixed to create a strong, dense core. A single, stable polymer cap is then fused around the wood-plastic composite core. The core is then co-extruded with a non-organic surface product to produce an excellent performance-capped composite deck.

This composite product features a unique blend of premium non-reactive color pigments, UV inhibitors, antioxidants, and mildew inhibitors. The combination of these properties provides the add-on composite decking with excellent resistance to sunlight, stains, mold, and bacteria. It also ensures the long-lasting durability and outstanding color of the decking compound. Adding colored pigments at precise intervals during the manufacturing process results in distinct multi-tonal streaks. For this reason, we have composite decking in a variety of colors. Such as redwood composite decking, blue composite decking, teak composite decking, etc.

Advantages of capped composite decking

Environmentally friendly and sustainable

Two other hallmarks of capped composite decking are environmental friendliness, sustainability, and a high percentage of recycled content. Composite decking is made from recycled materials. Wood fibers can be used from lumber mill waste. And plastics can be used from plastic waste generated in the course of life. Using these recycled materials prevents further deforestation. And at the same time prevents excessive plastic waste from polluting the environment.


In addition to enhanced durability and performance, four-sided capping means more versatility. This outdoor deck is reversible, which offers several advantages over non-reversible boards. For example, it has less sheet cutting and less material waste. It can also be embossed with different textures on both sides of the deck, thus increasing design options and visual appeal.

Capped composite decking also has a polished appearance on the top and bottom, making them ideal for use as a second deck. In addition, they feature grooved edges for concealed fasteners. Concealed fasteners provide a smooth, fastener-free surface for your deck. And giving your outdoor deck a more aesthetically pleasing appearance.
