Every kind of product has an extraordinary soul, and every kind of process contains the spirit of craftsmanship. We are committed to producing the best composite decks.
COOWIN's story began in 2000 as one of the first composite decking brands in China. The founder, Mr. Leo, invested a lot of money and energy in introducing formulas and technologies from the US. Then, this small factory has grown step by step to become one of the most well-known wood-plastic enterprises in China.
At present, COOWIN’s self-developed formula has obtained national patents, and each raw material has strict physical and chemical indicators; the production equipment specially designed for COOWIN has been put into use.
