Aluminium magnesium, manganese plate mainly divided into Gao Libian and short side two (this and LouCheng plate is divided into open, keep silence is the same reason), Gao Libian edge is just some of the industry with short term, its scientific name should be upright single oversew and vertical double side whipstitch, rib respectively is 65 mm and 25 mm high, commonly used models for 400 and 400. In modern architecture, these two kinds of aluminum magnesium and manganese alloy plates are widely used, and the main differences are discussed below.
1. Water resistance: the high edge aluminum magnesium manganese plate is more advantageous in water resistance, which is determined by the height of the rib.
2. Beauty degree: from the outside, the finished low side aluminum magnesium manganese plate is more beautiful than the high side.
Three, use: under normal circumstances, the use of both is the same, are used for roofing, but in the absence of special requirements, short vertical side aluminum magnesium manganese roof plate for private villa is more, more Gao Libian aluminum magnesium manganese plate used in the gym.
