Steel Building

1.The metal prefab buildings Materials 
Beam and post: GB Q235/Q355B grade, welded H steel section. 
Sub steel structure: GB Q235B grade, steel bar, pipe, angle steel, etc. 
Purlin: Galvanized C section. 
Maintenance: Roof, wall, skylight, floor deck
The minimum size of the fillet welding for any which not defined in the 
drawings shall be 6mm with full welding. 

2.Fasteners( bolts and nuts) for jointing 
High Strength bolts 10.9 grade used to connect the Steel Columns and pressure type high strength bolts 10.9 grade used to connect the constructional elements. 

3. Derusting and painting 
Shot blasting to 2.5 and Applying of Paint with following 
1st coat of Primary anti-rust paint 30 microns 
2nd coat of Primary anti-rust paint 30 microns

4. Loads 
Roof dead load: 0.25 kN/m 2
Roof live load: 0.3 kN/m 2
Wind speed or wind load: 80~110 km/h
Floor dead load: 0.3 kN/m 2
Floor live load: 0.25 kN/m 2

The advantageous for steel building
1). Large interior open spaces benefit for commercial structures, warehouses, workshops, storages, shopping center, stadium, etc
2). The system can use less steel to achieve the same structural scale, which is more economical.
3). They have immense strength, pretty much stronger and more durable than other construction materials, the main structure can last around 50 years.
4). All the framing components cut, welded, and drilled at the factory, it makes the installation work at a high speed assembled at a construction site.
5). The steel building is also a green building system, cause steel can be recycled repeatedly that is energy efficient and eco-friendly.

Steel buildings can work for any building application
A.High-rise buildings like a multi-story office building, residential apartment buildings,
commercial buildings center etc.
B.Warehouse building, similar to the industrial buildings, manufacturing plants, steel workshop.
C.Agricultural buildings, grain barn, storage buildings, suburban buildings.
