Determination of heavy steel structure and light steel does not have a uniform standard, a lot of experienced designers and project managers are often not fully say it, but we can be judged and considered with some data:
1, Lifting capacity of Over head crane : lifting capacity more than 25 tons, can be considered as a heavy steel structure .
2, The quantity of steel per square meter: greater than or equal 50KG / M2, can be considered heavy steel structure .
3, Plate thickness of main components: equal or bigger than 10MM, light steel less used such thickness .

In addition, there are some reference value: if the cost per square meter, the maximum component weight, the maximum span, structure, higher eaves, whether when these heavy steel or lightweight steelcan provide empirical data to determine the plant, of course, many buildings are light and heavy steel there. But there is something we can be more sure that heavy steel: such as: petrochemical plant facilities,power plants factories, large span of stadiums, exhibition centers, high-rise or super high-rise steel structures.
