Product Description

More details of the steel structure frame storage shed warehouse building with tansverse external PU heat insulation sanwich panel  (steel frame/steel shed),grouped by H section steel beam and column,the C section steel as purlin for installing the roof and wall panel. After finish install the building, the fashion and good looking is because this kind of PU panel is different to normal vertial installed sandwich panel, it is installed follow tansverse. The connected part between two panels are special design,in order to match the requirement for waterproof and heat insulation .






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 :
