Steel structure construction can be a industrial, agricultural or commercial building for storage or production of goods, often have cranes and forklifts for moving goods around the structures.
It requires easily transported, fast assembled without skilled labor, without affecting the quality and durability. And design allows for strength and sturdiness, protection against earthquakes and wind, and is relatively cheaper when compared to other material building. Steel structure widely applied to warehouse, factory, workshop, storage, garage, hangar, etc., also you can add the partition wall or first floor( second floor) according to multi-purpose.
Steel structure adopts Q345B welded H type steel, Q345B steel square tube, Q235B C type steel and Q235B Z type steel to combine or build framework. Roof and wall are color compressing corrugated steel sheet or color steel sandwich panel.
Q345B is one of low carbon alloy steel. Welded H section Q345B steel with high strength, stonger buckling resistance performance, can save 10%-15% material, 30%-40% weight of structure in buildings and 15%-20% weight of structure in bridge than hot-rolled H steel. Compare to hot-rolled H steel, welded H section steel have high-accuracy size performance, can be customized.
