PrimeDeck WPC Batten-Keel – Structural Support System for Outdoor Decking
The PrimeDeck WPC Batten-Keel also known as wood plastic composite joist is a core structural component used beneath outdoor composite decking boards to provide a strong, stable, and level installation base. Engineered for Malaysia’s tropical climate, these battens are designed to withstand heavy rainfall, humidity, UV exposure, and temperature fluctuations, ensuring long-term deck performance for both residential and commercial projects.
Manufactured from high-density WPC material, PrimeDeck battens resist rot, warping, termites, and moisture absorption—making them a superior alternative to traditional timber joists. They maintain consistent board alignment, support load distribution, and improve drainage airflow below the deck surface, reducing water retention and surface deformation.
PrimeDeck WPC battens are compatible with concealed fixing systems, starter clips, L profiles, and end covers to form a complete outdoor decking solution. Easy to cut, drill, and install, they allow contractors to achieve faster construction timelines while delivering premium structural integrity.
