Stable Light Steel Structure Construction for Air Bridge

Africa steel structure modular air bridge is made by square tube,checker steel plate,finish welding and assembly at workshop,all big air bridge seperate into a few part in order to fit the size of internation shiping container for delivery.More details of the steel structure workshop,grouped by H section steel beam and column,the C section steel as purlin for installing the roof and wall panel :
Steelwarehouse 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 canreach 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 )
