4-sided capped composite decking, also known as co-extrusion WPC decking, is an advanced outdoor decking solution manufactured with a protective polymer cap layer covering all four sides of the board.
Compared with traditional uncapped WPC decking, the full cap structure provides enhanced protection against moisture, stains, fading and outdoor weather exposure.
Capped composite decking is known for its low maintenance requirements, as it doesn’t require the regular staining, sealing, or painting that traditional wood decks often do. It’s a popular choice for homeowners seeking a durable, long-lasting, and attractive decking option that can withstand various weather conditions.
Capped composite decking refers to the protective outer layer or cap that is typically made of a high-performance polymer. This cap shields all four sides around its inner WPC core from the elements, making the decking even more resistant to staining, fading, and general wear and tear.
The core is from Bongywood wood plastic composite materials, which uses recycled plastic and recycled wood.

Capped composite is also called co-extrusion WPC. it has an advanced tough plastic shield encasing all four sides around its inner WPC core, which provides added protection against the elements and everyday living.
The main difference is that capped composite decking has a plastic cap or shell that encases the composite core. While the cap provides added protection against the elements and everyday living, so capped composite decking claims to more durable and has better mold, stain and fade resistance than uncapped composite decking.

4-sided capping ensures the entire board, including the bottom and the grooves, is protected from moisture. This prevents “cupping” or warping caused by moisture absorption from the underside of the deck.
Capped composite decking can get warm in direct sunlight, but it generally doesn’t become as scorching hot as some traditional wood decks. Choosing lighter-colored decking can help reduce heat absorption.
