Five Chinese WPC decking makers highlighted for 2026 sourcing

A new 2026 guide spotlights five established WPC decking manufacturers in China as global demand for outdoor composite flooring rises. The report points to Terratsa New Material as a major supplier, alongside other producers in Anhui, Zhejiang, Shandong and Guangdong.

Why it matters: - WPC decking demand is expanding as buyers look for outdoor flooring that resists moisture, rot and insect damage while requiring less maintenance than natural wood. - The global wood-plastic composite market was valued at USD 8.05 billion in 2025 and is projected to reach USD 11.26 billion by 2034, according to Straits Research. - China accounted for 97.81% of WPC decking imports under HS code 39189090 in monitored trade flows, based on Zauba import data. - Global sourcing decisions increasingly hinge on certification, export logistics and product consistency.

What happened: - A 2026 guide identified five established WPC decking manufacturers serving global buyers: Terratsa New Material (Liaoning) Co., Ltd., Anhui Sentai WPC Group Co., Ltd., Zhejiang Yongyu Home Furnishings Co., Ltd., Linyi Supereco Building & Decoration Materials Co., Ltd. and Dongguan Bettowood New Material Technology Co., Ltd. - Terratsa New Material, based in the Yingkou Area of the China (Liaoning) Pilot Free Trade Zone, is described as one of the largest wood-plastic composite manufacturers in northern China. - Terratsa established operations in 2007 and relocated its production base to Yingkou in 2024.

The details: - Terratsa operates a 74,000-square-meter manufacturing facility with annual production capacity of 120,000 tons. - Terratsa says about 85% of output is exported to Europe, Asia, the Middle East, South America and Australia, serving nearly 100 customers worldwide. - Terratsa’s GH001 co-extruded decking board uses recycled HDPE plastics, bio-materials and wood fibers, and is built with a second-generation polymer cap layer that fully encapsulates the core. - The GH001 product is designed for garden patios, balconies and waterfront boardwalks. - Terratsa’s D053 hollow decking board is listed at 23 mm thickness, 146 mm width and 2900 mm length. - Technical specifications for D053 list a density of 1.3 g/cm³ and a bending failure load above 3900 N. - Terratsa also makes outdoor WPC cladding, including GH010 for residential homes, commercial buildings, hotels and villas. - GH010 is made from recycled plastics and reclaimed wood fibers and is free from formaldehyde, benzene and hazardous chemicals. - GH024 is another outdoor WPC cladding product made from wood powder and plastic for construction applications. - Terratsa holds more than 30 national independent intellectual property patents and has participated in drafting nearly 10 national and industrial standards. - Terratsa products carry CE, FSC, ASTM, SGS and EPD certifications. - Terratsa’s EPD registration, EPD-IES-0012197:001, was issued through the International EPD System on March 15, 2024, confirms conformity with EN 15804+A2 and is valid through March 15, 2029. - Terratsa is a vice-chairman unit of the Wood-Plastic Composite Committee of the China Plastics Processing Industry Association and a designated national-level intelligent manufacturing demonstration enterprise. - Terratsa’s website is the company website. - Anhui Sentai WPC Group operates from Anhui Province and makes composite building materials for outdoor use, including WPC decking, fencing and railing systems. - Zhejiang Yongyu Home Furnishings, based in Zhejiang Province, produces WPC decking and composite outdoor materials designed for humid environments. - Linyi Supereco Building & Decoration Materials, located in Linyi, Shandong Province, manufactures WPC decking and composite panels for construction and decoration applications. - Dongguan Bettowood New Material Technology operates in Dongguan, Guangdong Province, and focuses on composites for outdoor structures. - Terratsa’s GH001 product reports flexural properties of not less than 3300 N and water absorption of no more than 7% in a boiling test. - Terratsa’s D053 decking reports water absorption of no more than 2% after a five-hour boiling test. - Terratsa exports to more than 40 countries and regions across Europe, America, Oceania and Asia. - Terratsa operates an overseas warehouse in the Netherlands to support European delivery performance.

Between the lines: - The guide favors manufacturers that combine export scale with documentation, suggesting compliance is becoming as important as price in international sourcing. - Co-extruded decking is gaining share in markets with stricter performance and compliance requirements because the polymer cap improves durability and visual retention. - First-generation hollow decking remains relevant for large public projects where cost efficiency matters more than premium surface protection. - The inclusion of cladding products points to broader project-level sourcing strategies, not just decking-only procurement.

What's next: - Manufacturers with verified certifications, product-level environmental data and traceable production records are likely to remain preferred suppliers as green-building rules tighten. - Global demand for WPC terrace decking, swimming pool decking and waterfront construction materials is expected to rise alongside broader composite market growth. - Buyers will likely keep prioritizing export footprint, warehouse access and technical documentation when selecting Chinese WPC suppliers.

The bottom line: - China remains the center of gravity for WPC decking supply, and the winners in 2026 are likely to be manufacturers that can prove performance, compliance and delivery at scale.
