Steel structure is a structure composed of steel material, which is one of the main types of building structure. 

The structure is mainly composed of steel beam, steel column, steel truss and other components made of type steel and steel plate, and the components or components are usually connected by welding joints, bolts or rivets. Because of its light weight and simple construction, 

it is widely used in large factories, venues, super high-rise and other fields.

Steel is characterized by high strength, light weight, good overall rigidity and strong deformation capacity, so it is particularly suitable for large span and high and heavy buildings; material homogeneity, good ideal elastomer, most meet the basic assumptions of general engineering mechanics, 

good plasticity and toughness, great deformation, can withstand power load; construction period is short; its high degree of industrialization, high mechanization degree of professional production.

Steel structure should be studied as high strength steel to greatly improve its yield point strength; and to roll new types of steel, such as H steel (also known as wide flange steel) and T steel and pressure steel plate, to meet the needs of large span structure and super high-rise buildings. 

In addition, there is no heat bridge light steel structure system, the building itself is not energy saving, this technology with clever special connector to solve the problem of cold and cold bridge; small truss structure makes the cable and upper and lower water pipe from the wall through, construction and decoration are convenient.

Roofing system 

It is composed of roof frame, structural OSB panel, waterproof layer, light roof tile (metal or asphalt shingles) and related connections. 

Wall system

The wall of the light steel structure residence is mainly composed of wall frame columns, wall top beam, wall bottom beam, wall support, wall panels and connecting parts. 

Building light steel structure housing generally the horizontal wall as the structure of the bearing wall, wall column for C light steel components, the wall thickness according to the load, usually 0.84~2 mm, wall column spacing is generally 400~600 mm, building light steel structure residential this wall structure layout, can effectively withstand and reliable transfer vertical load, and convenient layout, but the mat building light steel structure residential wall structure can not bear the horizontal load.

Why chose steel structure building?

1. High material strength and light own weight

High steel strength and high elastic modulus. Compared with concrete and wood, the ratio of density and yield strength is relatively low, so under the same stress condition of steel structure components are small cross section, light weight, easy transportation and installation, suitable for large span, high height, heavy bearing structure.

2. Steel toughness, good plasticity, uniform material and high structural reliability

Suitable for bearing the impact and power load, with good seismic performance. The internal tissue structure of the steel is uniform, close to the isotropic homogeneity. The actual working performance of the steel structure is more in line with the calculation theory. So the steel structure has a high reliability.

3. High degree of mechanization of steel structure manufacturing and installation

Steel structure components are easy to manufacture in factories and construction site assembly. Factory mechanized manufacturing steel structure components finished product high accuracy, high production efficiency, site assembly speed, short construction period. Steel structure is the most highly industrialized structure.

4.Good sealing performance for steel structure

Because the welding structure can be completely sealed, can be made into air tightness, water tightness are very good high pressure vessel, large oil tank, pressure pipe, etc.

When the temperature is below 150℃, the steel properties vary very little. Therefore, the steel structure is suitable for the thermal workshop, but when the surface of the structure is affected by about 150℃ of thermal radiation, the heat insulation plate should be used to protect it. At 300℃ -400℃. Steel strength and elastic modulus have decreased significantly, when the temperature is about 600℃, the strength of steel tends to zero. In buildings with special fire prevention needs, steel structures must be protected with refractory materials to improve the fire resistance rating.

6. Poor corrosion resistance of the steel structure Especially in the humid and corrosive media environment, easy to rust. General steel structure should be rust removal, galvanized or coating, and should be maintained regularly. 

For the Marine platform structure in seawater, special measures such as "zinc block anode protection" should be adopted to prevent corrosion. 

7.Low-carbon, energy-saving, green and environmental protection, reusable 

The demolition of steel structures can hardly produce construction waste, and the steel can be recycled.
