Heavy Steel Structure

First, the heavy steel
1, plant driving weight lifting: ≥ 25 tons.
2, steel consumption per square meter: ≥ 50kg/m2. Such as: petrochemical plant facilities, power plants plant, large-span stadium, exhibition center, high-rise or high-rise steel structure.
, Light steel and heavy steel qualitative difference
Determine the structure of heavy steel and light steel structure does not have a unified standard, a lot of experienced designers or project managers are often not fully understand, but we can consider some of the data integrated and to be judged:
1, plant Driving lifting weight: greater than or equal to 25 tons, can be considered as the most important steel structure.
2, the amount of steel per square meter: greater than or equal to 50kg/m2, can be considered to be heavy steel structure. 3, the main components of plate thickness: greater than or equal to 10MM, light steel structure with less.
Also, there are reference values: such as the cost per square meter, the maximum component weight, maximum span structure, eaves higher, these in determining whether or not the plant is the weight of steel or light steel can provide empirical data, of course, a lot of buildings are light and heavy steel has. But we can be sure is heavy steel: such as: petrochemical plant facilities, power plants, plant, large-span stadium, exhibition center, high-rise or high-rise steel structure.
