Characteristics:

1. Wide span: single span or multiple spans, the max span is 36 m without middle column

2. Low cost and high quality

3. Fast construction and easy installation

4. Long using lifespan: up to 50 years

5.Others: environmental protection, stable structure, earthquake resistance, water proofing, and energy conserving.

Applications:

1. Large span structure
Used in the town hall, gymnasium, exhibition hall, theater, hangar, car garage, etc. The structural systems used mainly include frame structure, arch structure, grid structure, suspension structure and prestressed steel structure.
2. Plant structure
Such as the open hearth workshop, the initial rolling workshop, the mixed iron furnace workshop of the metallurgical plant, the cast steel workshop of the heavy machinery factory, the hydraulic press workshop, the forging workshop, etc.; the shipyard workshop of the shipyard; the assembly workshop of the aircraft manufacturer. The main load-bearing skeletons of these workshops are often steel structures in whole or in part. 3.
3. High-rise building
It is used for high-rise buildings such as hotels, restaurants, apartments and office buildings.
4. Tower structure
Used in TV towers, microwave towers, high-voltage transmission line towers, chemical exhaust towers, atmospheric monitoring towers, oil drilling towers, rocket launch towers and radio masts.

Advantages:

Steel provides several advantages over other building materials, such as wood:

Steel is structurally sound and manufactured to strict specifications and tolerances.
Any excess material is 100% recyclable.
Steel does not easily warp, buckle, twist or bend, and is therefore easy to modify and offers design flexibility. Steel is also easy to install.
Steel is cost effective and rarely fluctuates in price.
Steel allows for improved quality of construction and less maintenance, while offering improved safety and resistance.
With the propagation of mold and mildew in residential buildings, using steel minimizes these infestations. Mold needs moist, porous material to grow. Steel studs do not have those problems.
