Steel Structure Buildings In Angola

Angola steel structure building was built in 2009,as a manufacturer and supplier of Qingdao Xinguangzheng Steel Structure Company,we provided customer the complete materials,this building was used for steel warehouse,total area around 4000 square meter. Main steel structure used galvanized hot-rolled H steel. Single steel sheet roof and wall without heat insulation.There were two sets 5 tons 6m lift high overhead crane.The whole structures was connected by bolts and no welding on site.

What is steel structure building?

    Steel structure building is composed by steel structure material, is one of the main building structure types.Structure is mainly made of steel and steel plate, steel column, steel truss girder artifacts, such as weld is required between each components or parts, bolt, or rivet connection.Because of its weight is lighter, and the construction is simple, widely used in large factories, stadiums, high-rise, and other fields.  
The characteristics of steel structure building
  Steel is characterized by high strength, light weight, good overall stiffness and deformation ability, therefore, to build large span and super high, super-heavy buildings is suitable;Homogeneous and isotropic materials is good, is a ideal elastic body, the most in line with the general engineering mechanics basic assumption;Material plasticity and toughness, good can have large deformation, can bear dynamic load;Short construction period;Its high degree of industrialization, high mechanization degree of specialization of production can be performed. Steel structure components are easy to manufacture, site assembly in the factory.Mechanization of factory manufacture steel structure component products of high precision, high efficiency, site assembly speed up, short time limit for a project.Steel structure is one of the most industrialized structure.
Steel structure building fireproof performance 
When the temperature was below 150 ℃, the steel properties changed little.Thus the steel structure is suitable for the hot shop, but the structure surface at the thermal radiation of about 150 ℃, to adopt heat insulation board to protect it.Temperature at 300 ℃ to 400 ℃. The steel strength and elastic modulus were decreased significantly, the temperature about 600 ℃, the steel strength tends to zero.In buildings with special fire protection demand, steel structure must be preserved with refractory materials in order to improve the fire resistance rating.
The application of steel structure building
 Steel structure is widely used in residential, factory, warehouse, tower, power plants, Bridges, and other areas of the building.Steel structure industry is usually divided into light steel structure, high-rise steel structure building, steel structure residential steel structure, space and bridge steel structure of the five subclasse.
