For the 140*25mm WPC decking with 6 round holes and wide grooves, here's a one-paragraph introduction: This 140*25mm WPC decking features a 6 round-hole + wide-groove structure designed for drainage, ventilation, and load-bearing performance. The longitudinal round holes, combined with wide surface grooves, quickly channel rainwater away to prevent pooling and board damage, while internal airflow reduces moisture buildup and minimizes the risk of warping. The wide grooves improve slip resistance on wet days and help hide everyday scratches. The round holes reduce weight while maintaining solid load-bearing walls, offering better bending resistance and easier clip alignment during installation. This structure keeps the deck stable in both hot sun and humid outdoor conditions, with simple, low-maintenance cleaning.
