The difference between the synthetic tile tile roof and the ridge tile and their installation method
H steel structure I have seen roughly 3: 1 : 101: 151: 20 arc structure due to the structure are small profiles, completely ridge to stabilize the roof: 1: 3
Synthetic resin tile from the height of the ridge, for the different regions are not used, because to prevent the snow after the roof load is too large, the south from the ridge height is small, the north is large
5 or so triangular roof trusses mostly with double dorsal angle steel, adapted to a single span of the larger workshop: 1 : 5 about the specific information about the company building materials company
