Prefabricated Construction

Prefabricated building is an important achievement of the application of modern industrial technology in the field of  construction, of which the concept was originated in the early 20th century and finally realized in Europe in the 1960s.  In recent years, with the rapid development of materials, processes and information technologies, the advantages of  prefabricated buildings in saving materials, quickening construction, reducing waste and optimizing functions have  become increasingly prominent. Since 2015, the Chinese government has intensively promulgated a number of policies  and regulations to promote prefabricated buildings across the country, which has achieved breakthroughs and become  an important driver for the adjustment and upgrading of the industrial structure of China's construction industry.

Wiskind building envelope products follow the advanced concept of the prefabricated building. In terms of material  structure, system design, process flow, etc., its exterior façade, roof and other product series bring the advantages of  standardized design, factory processing, and modular construction of the prefabricated building into full play, while  always maintaining the industry-leading level. At the same time, Wiskind attaches great importance to the organic  combination of standardized products and customized designs, so as to meet the diversified and personalized needs of  the client, and fully explore the aesthetic value of prefabricated buildings.

A complete set of imported Italian Puma production lines adopts European advanced polyurethane core production technology and six-component foaming process to ensure the stability of product performance. The extra-long double track ensures the flatness of the product surface. Based on digesting and absorbing foreign advanced technology, the brand-new BiLAP™ production line developed by Wiskind has obtained nearly 300 technical improvements, including two invention patents for bonding technology, rock wool conveying and lubrication system.
