Huazhijie Plastic Building Material Co., Ltd.

Huazhijie Plastic Building Material Co., Ltd. is one of China's leading manufacturers of PVC profiles and synthetic resin roofing products. A subsidiary of Huashengda Holding Group Co., Ltd., the company was established in 1995 and operates from its headquarters in Deqing Economic Development Zone, Zhejiang Province — just 45 kilometres from Hangzhou. As the Chairman Unit of the Windows/Doors and Profiles Committee of the China Plastic Processing Industry Association, Huazhijie holds a position of genuine authority within China's plastic building materials sector. The company's 148,674 square metre production facility runs more than 10 advanced production lines imported from Singapore, Germany, Italy, and Austria, delivering an annual capacity of 120,000 tonnes — the highest export volume among domestic manufacturers in the same industry. The product range spans the full breadth of plastic construction materials: UPVC window and door profiles (casement, sliding, top-hung, and combined systems), ASA synthetic resin roof tiles, PVC fencing and balustrades, wall cladding panels, and a complete range of decorative trim and accessory profiles. All products are manufactured under a 'one body, three wings' structure: Huazhijie headquarters produces the PVC profiles, while three subsidiary companies handle decoration materials, fencing, and finished windows and doors. Huazhijie holds ISO 9001, ISO 14001, and OHSAS 18001 management system certifications, with international product approvals including CE (EU), AAMA (USA), and PCT (Russia). The company has been awarded the National Science and Technology Progress Award (2nd Prize), the Shanghai Science and Technology Progress Award (1st Prize), and the Zhejiang Provincial Science and Technology Progress Award, with nearly 100 patents to its name including 5 invention patents and 22 utility model patents. Huazhijie maintains representative offices in more than 40 Chinese cities and exports 51–70 per cent of production to over 40 countries across North America, South America, Europe, Southeast Asia, Oceania, and the Middle East, with an annual output value exceeding US$100 million.
