DNP International has consistently kept apace of developments in metal roofing systems in order to overcome problems of leakages, expansion and contraction due to weather conditions, insulation requirements and the maintenance of the original color. These changes have included various types of flat seam, standing seam systems, use of new types of metal and coatings. DNP International has consistently introduced new technologies and materials resulting in more efficient and aesthetic roofing for the many projects it has installed, primarily in China.
It has focused on efficient performance using simple connectors which avoid the need to drill into the roof during installation. DNP International’s metal roofing systems have become the first choice for many metal roofing projects.
One novel system consists of profiling the metal sheets and using polyamide brackets. These profiles can be applied to the required lengths according to the needs of the project. The installation is very simple, the workers just need to fix the brackets onto the purlin and then click the profiled plates onto the brackets with no drilling required. The outstanding drainage system ensures that the roofing system is absolutely leak-proof without the use of sealants or the use of waterproof strips. People can walk safely on the roof and the roofing system is strong enough to cope with extreme weather of strong winds, snow or hail.
We provide roofing systems for all kinds of metal materials – including aluminum, copper, titanium zinc, and Galvanized Aluminum-Zinc Alloy.
