Description of logistics warehouse in steel structure：
Qingdao Puhua Logistics Co.,LTD. totally has two logistics warehouses，the big warehouse with dimension of length 249.18m X width 90.48m X height 11.4 m，total area is 22,545.81 square meters，it’s canopy is 996.72 square meters. The warehouse adopts portal frame，design based on durable years of 50 years，earthquake resistance is 7 grade，fireproof is 2 grade，adopts fireproof paint for fire-resistance. Roof and wall use 75mm thickness heat insulation materials which will be done on site，no power ventalitor on roof and skylight sheet for lighting.
The small warehouse with dimension of length 129.18m X width 72.48m X height 7.3 m，total area is 9,363 square meters. It’s also adopts portal frame，design based on durable years of 50 years，earthquake resistance is 7 grade，fireproof 2 grade，adopts fireproof paint for fire-resistance. Roof and wall use 75mm thickness heat insulation materials which will be done on site，no power ventalitor on roof and skylight sheet for lighting.
The advantage of steel structure：
1, the steel structure bearing capacity of light weight and high: belongs to the lightweight high strength material
2, steel is the most close to homogeneous isotropic body: the steel cut into small pieces Every small pieces will have roughly the same mechanical properties And performance is also roughly the same in every direction Is the foundation of solid mechanics
3, good plasticity and toughness of steel: under static load steel have good plastic deformation capability
4, steel has good welding performance: the so-called "good" refers to steel welding performance after the welding process and welding can preserve the integrity of the welding part is not cracking properties
5, steel structure has the characteristics of no leakage, no matter adopt welding, riveting or bolt connection of steel structure can be sealed and no leakage
6, factory, construction steel structure manufacture assembly: component is lighter Construction is convenient The site covers an area of small short construction period Also facilitate the demolition of reinforcement and reconstruction
