Metal roofing system with double standing occlusive seam
(1)The whole structure is of good waterproofing water draining property. No matter what shape the building makes, it the seam can be fully occluded with no pin hole over the whole roofing. It can keep the roofing be flexible under temperature variation, to both refrain from thermal stress and water leakage due to the way the screw fixed in the system.
(2)Matured integrated design with hole on the roof and lightning protection system
(3)Good air permeability, which can keep the whole structure naturally dry of long term and extend its service life.
(4)Three-dimensional arc-irregular modeling is easy for processing.
(5)Simplicity in structure, light and safe, resistant to negative pressure of high strength, even applicable in typhoon and rainstorm regions.
