About Qingdao Wenrun Holding Co., Ltd.
Qingdao Wenrun Holding Co., Ltd., established in 2016 and headquartered in Qingdao, Shandong, is a Chinese manufacturer specialising in single-ply waterproofing membranes for roofing and environmental anti-seepage solutions, under the Wenrun brand. Its official English-language site develops in detail roof systems with PVC, TPO and EPDM membranes, from system design to fastening and installation processes.
TPO membranes, in standard thicknesses of 45, 60 and 80 mil, are joined by hot-air welding to form a continuous barrier, with both traditional mechanical fastening and non-perforated fastening variants that preserve the integrity of the sheet. PVC membranes provide UV resistance and fire-retardant behaviour for industrial and commercial roofs, and EPDM membranes offer elasticity and durability beyond twenty years, also as pond liners.
The company states ISO 9001 and ISO 14001 certifications and clients in more than sixty countries across Europe, North America, the Middle East and Southeast Asia. Its catalogue is completed by geomembranes, pond liners and system accessories such as screws, plates, termination bars, corners and flashing tapes, with fast production and FOB shipping from Qingdao for complete waterproofing projects.
