What is the amount of steel used per square meter of various buildings?

Understand the unit price per ton of steel structure, the owner is concerned about the price per square meter of the main steel structure of the steel structure house. This requires an understanding of the amount of steel used per square meter of the main structure of the building. Cost of steel structure per square meter (yuan/square meter) = steel consumption per square meter (kg/square meter) x comprehensive unit price of steel structure (yuan/kg).

The amount of steel used per square meter of steel structure building is related to the use function, structural layout, architectural modeling, external load and geographical environment of the building.

For example, the amount of steel per square meter of the Beijing Bird's Nest is much higher than that of other ordinary sports venues to meet the special building shape, which greatly increases the amount of steel per unit area.

Generally speaking, the amount of steel used for the main structure of the single-storey factory building is 25~100kg/square meter (calculated according to the construction area), according to the height of the factory building, span, structural layout, driving tonnage, wall and roof material type, external suspension weight, local wind and snow earthquake natural environment and other factors.

Multi-storey workshop (building) of the main structure of the steel quantity is 35~150 kg/m (calculated according to the construction area). In addition to the same influencing factors as the single-storey plant, the operating weight and other live loads of each layer of equipment are also influencing factors.

For large-span space buildings, the amount of steel used in buildings of different shapes varies greatly, and there is no obvious rule.

For example, in recent years, the rapid development of large-span coal shed steel structure span, roof load is small. The amount of steel used in the main structure is 40~80kg/m2 (calculated by surface area), and the influencing factors are similar to those of a single-storey plant.
