Traditional WPC Decking
Traditional WPC Decking (Wood Plastic Composite) combines recycled wood fibers and plastics to create an eco-friendly, durable surface. Scratch-resistant, waterproof, fireproof, and slip-resistant, it requires no staining or sealing. Ideal for patios, poolsides, and commercial spaces, it offers decades of low-maintenance longevity for a sustainable, stylish alternative to traditional materials.
Composed of 50–60% wood fibers (sawdust, rice husks) and 40–50% recycled thermoplastics (HDPE/PP), bound with additives like coupling agents and colorants.
Achieves 1.2–1.8% water absorption (ASTM D1037), 75% lower than pressure-treated lumber, but higher than co-extrusion WPC (<0.8%)
Shows ΔE 3–5 color shift after 2,000 hours (QUV testing), requiring UV-inhibitor additives to slow fading.
Susceptible without biocides; mold resistance ratings typically Class 3 (ASTM G21), versus Class 1 for co-extruded WPC
Annual cleaning with pH-neutral detergent; occasional sealing recommended for stain-prone areas.
Retains 85% flexural strength after 50 cycles (ASTM D6662), but surface may crack in extreme cold (-20°C).
10–15 years with proper care, versus 25+ years for co-extrusion WPC.
Limited to light traffic (residential use); flexural strength 25–30MPa vs. 35–45MPa in co-extruded grades.
Lower upfront cost ($15–25/sq.ft installed) and simpler installation, but trades off long-term durability.
