What are the differences between light steel structure and heavy steel structure?Let’s follow the steel component manufacturers to understand

Concept of light steel structure

(1) The main load-bearing structure is single-span or multi-span solid abdominal portal frame;

(2) Having light roof and light exterior wall;

(3) No bridge crane or A1 ~ A5(light and intermediate) working class bridge crane or 3T suspended crane with lifting weight of no more than 20T;(There is no restriction on the single beam crane here, mainly because the lifting weight of the single beam crane is generally within 5T, the use of imported electric hoist can reach 10T, such as LD type, so there is no restriction on the single beam crane specification)

Here, the light weight mainly means that the enclosure is made of light material, and the main section of the member is the H-shaped section welded by the medium thickness (6-12mm thick) steel plate.Thus the current meaning of light steel mainly refers to the solid belly door type rigid frame structure in accordance with the provisions.

2. In addition to the above rigid frame structure, the following structural forms should also belong to light steel structure according to the cross section composition of the main stressed members:

(1) The structure made of cold-formed thin-walled steel;

(2) The structure made of round tubes, square tubes, rectangular tubes, etc.;

(3) The structure made by the combination of the above various components.

3, according to some reference value, such as per square meter of steel content (as limit 45 to 50 kg/m2), the main component of section forms (H shape, rectangle, circle, etc.), the thickness of the steel plate (with 12 mm to limit), the largest component weight within 3 t (control), the largest span (usually within 36 m), structure (such as gantry frame or a similar structure), factory building eaves high within 12 m (control), structure (control) in 9 m width and so on, these data when determine whether factory belong to light steel can help.

The concept of heavy steel structure

1. Heavy steel structure is mainly used in large plant projects, such as power plant plant, metallurgical and petrochemical plant, large machining plant and assembly plant, etc

2, in fact, for the heavy steel structure called “normal steel” is more appropriate.Because of the wide range of ordinary steel structures, they can contain all kinds of steel structures, regardless of the size of the load, and even much of the content of light steel structures comes from the steel structure specification.

3. The characteristics of chonggang structure are basically as follows:

(1) Lifting weight of workshop crane: more than 20 tons and more than 2 sets;

(2) Steel quantity per square meter: more than 50kg /m2;

(3) The thickness of the steel plates of the main members is generally greater than 12mm, and the sections of the members are mostly formed steel composite structures;

(4) The eaves of the workshop are high and the structure has a large width;

4 sports stadiums and exhibition centers, large span, high or whether high-rise steel structure could be called chongqing steel structure, although this kind of structure steel quantity is large, the range is big, but the structure of the stadium, exhibition center type spatial structure is more, top or high-rise steel structure frame shear wall (support system), with a significant difference between the light steel structure, I think this kind of architecture should be points within their respective structure type is better.

Above is the introduction of the difference between light steel structure and heavy steel structure, I hope you will like it!We are a manufacturer of structural Steel~
