At present, the main use of the mullion way is that the span of the beam can not be too large, otherwise the number of structural columns will increase. Mullion generally rests on the floor, so the layout is more flexible. In most of the domestic use of component assembly, construction is relatively slow, due to low precision and construction requirements. (The type of aluminum alloy glass curtain wall)
