China Comfortable Prefabricated House Steel Frame Building Steel Structure House

Long life time prefabricated steel structure house is popular to the whole world,the main materials for the metal frame are square tube,H section steel,angle steel,round tube and so on,the roof and wall materials are ALC cement composite board, the thickness can be 50mm, 75mm, 100mm, 125mm,150mm,200mm,clients can according their requirement to choose the suitable thickness . The flooring of building is ALC cement board or place concrete at project site . The life time of whole steel building same to traditional concrere building,more than 50 years,but more fast for installation and cheaper.
Good cladding materials for long life time steel buildings-ALC board
Autoclaved aerated cement panel (block) refers to the siliceous and calcareous materials as the main raw material, aluminum powder as the foaming agent, through high temperature and pressure steam to produce the panel (block),the panel include reinforced mesh to enhance the strength. It is a lightweight, high strength and porous green wall material. It is not aging and has good durability. The service life of the panel(block) can be matched with the service life of all kinds of buildings. Therefore, it is commonly used as thermal insulation board, wall board, , Roof, floor, fire board and so on for different kind of steel structure building and traditional concrete building.
Common size specifications: Length is 0-6 meters, width: 600mm, thickness 75,100,125,150,175,200,250,300 mm.
As aerated cement filled with 2mm closed pores, can effectively delay the spread of water, if the same volume of aerated blocks and clay bricks immersed in water at the same time for 72 hours, almost all gaps in clay bricks are filled with water, but aerated Block only 1/3 void filled with water
Steel warehouse is the third generation construction. It combines H section and c/z section into the frame with the profiled steel sheet or sandwich panel as the wal and roof. The traditional reinforced concrete construction has aready been taken place by this kind of construction in developed contries. It has many excellent charateristics such as light weight, larger span, less marerial, low cost, less foundation, short building cycle, safe, beautiful, ect. It is widely used in single industrial factory, warehouse, business construction, office, parking lots, residence and so on.
STEEL STRUCTURE MEMBERS PRODUCTION (Fabrication) PROCESS :
1. Prepair raw materials : cut steel plate or use internation size H section steel and angle steel,round tube,round steel,square tube etc.;
2. Assembly and welding: our welders will follow the drawings to assembe the steel members and weld them together as a entire beam/column/brace and so on; (Our quality inspector will check the steel pieces after finish welding,this is the first quality check)
3. Sand blast : After finish welding and polishiing,our sand blast effect can reach internation 2.5 high grade,very good for resist rust; (Secondary quality check)
4.Paint : Within 2 hours after sand blast,all the steel members should be paint. Client can choose any color and any brand of paint. (The third quality check)
5. Inspect the goods by client : After we finish a part of fabrication work,we will invite clients to check the goods before we pack the steel frame.
6.Packing and loading : If clients require us to load the goods by close containers,we will pack the steel structure members one by one on the steel skid and tie the whole steel package well. (The fourth quality check )
Please check the details drawings as follow :

General materials for whole steel building:
