This is a park project in the United States. Before selecting materials, customers were more concerned about the safety of the product. After a number of sample comparisons, they finally chose COOWIN’s wood-plastic products. The wood-plastic railing and decking not only retain the texture of solid wood but also have the unique characteristics of water-proof, anti-corrosion, and mildew-proof of wood-plastic. In order to ensure the safety of use, the customer use 25mm solid composite decking, even when the flow of people is large, it is still intact.
