一。镀锌楼承板原材料：镀锌板密度为镀锌板单价（3800元/吨）的7.85倍，镀锌板厚度（1.0 mm、1.2 mm等）x镀锌板宽度（900 mm/1000 mm/1250 mm等）=该楼承板每米原材料价格。
Compared with the previous buildings, the current building level has been improved a lot, not only the construction time has been
shortened a lot, but also the materials used have been much more advanced than the previous ones. The main contribution of the time greatly reduced in the steel structure construction is the floor bearing plate.
How do we test the qualified floor bearing plate? The first is to pass many dynamic loading tests, that is to say, only through many dynamic tests can we judge whether the comprehensive ability is qualified, and can we get how much load we can bear. The second is the fire resistance test, which must meet the requirements of building insulation.
The general use is mainly in some large and medium-sized construction projects, such as large-scale shopping malls, supermarkets, concert halls, theaters and gymnasiums. The reason why they are selected by these large-scale places is enough to witness the development and importance of the floor bearing plate.
The price composition of galvanized floor bearing plate is as follows:
1. Raw material of galvanized floor bearing plate: the density of galvanized coil is 7.85x the unit price of galvanized coil (say 3800 yuan / ton), the thickness of galvanized coil (1.0mm, 1.2mm, etc.) x the width of galvanized coil (900mm / 1000mm / 1250mm, etc.) = the price of raw material per meter of this floor bearing plate.
2. Of course, if there is a cost for molding, the cost varies from 1-10 yuan per meter, which should be determined according to the version. For example, the price of the closed floor bearing plate is 3-5 times higher than that of the conventional floor bearing plate, because it needs more labor and low efficiency when it is manufactured.
3. There are also miscellaneous expenses, such as taxes and transportation expenses.
