The main beam of house top frame is made of galvanized steel with the special section, rolled by equipment and pre-laid the drainage ditch. As well, the waterproof adhesive tape, and waterproof fastener and waterproof glue shall be used for secondary waterproofing when   consolide the houses.

 

There are no nails on the surface of house, and 360 degree vertical lock seam is used to occlude the ceiling and roof. Butyl glue is used around the occlusal place  to ensure water-proof.

 

 

GS housing take structural safety as our own responsibility, Pursuing project standardization,

Occupy the market with the safety, comfort, energy saving and environmental protection containter houses .

Shoulder social responsibilities and eliminate potential safety hazards.
