2. Disadvantages of WPC decking boards

If you buy a low-quality product, you will have problems such as bending, warping, arching, cracking, and serious color fading after using it for one or two years, or even less than a year. For example, the crimson becomes pink.

(2) In order to save costs, some plastic wood material manufacturers will reduce the use of antioxidants and other related additives, and even reduce the amount of wood fiber, bamboo powder and other wood fibers (increase the amount of cheap talcum powder or light calcium carbonate), as a result, engineering accidents such as "severe fading, brittle material, and easy cracking" will be inevitable.

3 Tips to Identify High-Quality WPC Boards

Smell the Material: Quality WPC should have a faint wood scent, not a strong chemical plastic smell.

Verify Certifications: Always ask for CE, ISO, and Intertek test reports.

Common Concerns & Expert Answers: Is WPC Decking Right for You?

Yes. Like all materials, WPC has a thermal expansion and contraction rate. However, Sundi’s advanced HDPE formulation significantly minimizes this movement compared to standard WPC. To ensure a stable deck, we provide professional installation kits and specialized hidden fasteners that maintain the necessary expansion gaps automatically, preventing warping in extreme temperatures.
