As one of the earliest manufacturers of PP-R pipeline systems in China, we put every effort into product research and development. Having imported German raw material, equipment and manufacturing technology, all of our pipes and related fittings meet DIN8077 and DIN8078 industrial standards set by that country.

With factory facilities covering an area of 30,000 square meters, after several years' of development we now own 6 advanced automatic production lines, outputting products with diameters from 20 to 160mm. Available in 4 pressure grades, 3 colors (white, gray, green) and nearly 300 specifications, these products are marketed under our proprietary "SD®" brand. Exporting close to one quarter of all items produced, we have won an envious reputation among clients in Europe, South America, the Middle East and Southeast Asia.

Employing more than 50 technical staff, we always place much emphasis on quality control. In 2000, our products were evaluated as meeting requirements set by the People's Insurance Company of China, in addition to being certified as ISO9001 compliant by SGS. Furthermore, we have been issued user authorization for our Vestolen P9412 material by SABIC EuroPetrochemicals (formerly known as DSM).

Filling the needs of clients throughout the international market, we are offering world-standard products for all buyers.
