Liaoning FuRuida Construction Technology Co., Ltd. Heavy Steel and Light Steel Features


The classification of steel has heavy steel and light steel, so what are their characteristics? The difference between the structure of heavy steel or light steel in fact, there is no completely unified standard, many experienced structural designers can not fully understand, mainly according to the following a few to make a simple judgment:
 
1. Heavy steel structure: If the lifting weight of the factory building is greater than or equal to 25 tons, it can be considered as heavy steel structure..
 
2. Steel consumption per square meter: 50KG/m2 or more, which can be regarded as heavy steel structure.
 
3, the main component steel plate thickness: greater than or equal to 10MM, light steel structure with less.
 
In addition, according to the cost per unit meter, the weight of the largest steel member, the span, the height of the eaves, the structural form, etc., it can be judged whether the plant is heavy steel or light steel. In daily buildings, both light steel and heavy steel are very common types. Generally speaking, it can be sure to be heavy steel: stadiums with large span, high-rise and super high-rise buildings, power plant buildings, etc.
 
At present, there are no specifications and technical documents in the country to explain heavy steel and light steel, and the general steel structure is "general steel. The application range of ordinary steel structure is very wide, including many contents of various steel structures. The steel structure of houses is generally light steel, which is more common in life.
 
For light steel is a person more vague nouns, generally can have two kinds of understanding. One is the light steel structure of round steel and small angle steel in chapter 11 of the current code for design of steel structures (GBJ 17-88), which refers to the light steel structure made of round steel and angle steel smaller than L45 * 4 and L56 * 36*4.
 
Through the above description, it can be clearly separated that heavy steel and light steel are not distinguished by weight, but according to the weight of the enclosure materials they bear.
