ANJI ZHENGYUAN WPC products have varying warranty periods (e.g., 10
years for wall cladding, 5–30 years for composite decking);the warranty
covers manufacturing defects (like splintering or rot) under proper
installation/use, with remedies including replacement or prorated
refunds based on usage duration. Claims require proof of purchase,
warranty documents, and defect evidence submitted within the warranty
period (≤30 days), while unauthorized repairs, improper use, intentional
damage, or issues with third-party parts void coverage—all terms follow
the official WARRANTY& LIABILITY.
