Prefab Building Features

• High material strength and light weight of itself
  Steel has high strength and a high modulus of elasticity. Compared with concrete and wood, its density and yield strength ratio is relatively low, so the steel structure under the same stress conditions of the component section is small, lightweight, easy to transport and install, suitable for large spans, high height, and heavy load-bearing structure.

• steel toughness, good plasticity, uniform material, high structural reliability
  Suitable for bearing impact and dynamic loads, with good seismic performance. The internal organization of steel is the homogeneous, nearly isotropic homogeneous body. The actual working performance of the steel structure is more in line with the calculation theory. So the reliability of the steel structure is high.

• High mechanization of steel structure manufacturing and installation
  The steel structure components are easy to be manufactured in the factory and assembled at the site. Factory mechanized manufacturing of steel structure components has high precision, high production efficiency, fast site assembly, and a short construction period. The steel structure is the most industrialized kind of structure.

• The good sealing performance of the steel structure
  Because the welded structure can be completely sealed, it can be made into high-pressure vessels, large oil pools, pressure pipelines, etc. with good gas and water tightness.

• The steel structure is heat resistant and not fire resistant
  When the temperature is below 150℃, the nature of steel changes very little. Therefore, the steel structure is suitable for hot workshops, but when the surface of the structure is subjected to heat radiation of about 150℃, a heat insulation plate should be used to protect it. When the temperature is 300℃ -400℃. Steel strength and modulus of elasticity are significantly reduced, and the strength of steel tends to zero when the temperature is around 600℃. In buildings with special fire protection needs, the steel structure must be protected by fire-resistant materials to improve the fire resistance level.

• the poor corrosion resistance of steel structures
  Especially in an environment of moisture and corrosive media, it is easy to rust and corrosion. Generally, steel structures should be de-rusted, galvanized, or painted, and maintained regularly. For the marine platform structure in seawater, special measures such as “zinc block anodic protection” should be adopted to prevent corrosion.

• Low-carbon, energy-saving, green, reusable
  The dismantling of steel structures will not produce almost any construction waste, and the steel can be recycled and reused.
