Structure of shelf

　　The overall structure of the rack in the attic is assembled, without on-site welding, and the overall appearance is generous. Compared with concrete structure or steel structure, the bottom shelf itself plays a supporting role in the upper layer, which has the advantages of low cost and high space utilization.

　　The shelf panels in the attic have flat plates, patterned steel plates, punched steel plates and other varieties to meet different requirements for fire protection, ventilation, lighting and other uses. Forklift, hydraulic lifting platform and cargo elevator can be used for cargo up and down floors; Small trolleys are usually used for the transportation of goods in the same layer.

　　The shelf in the attic usually has a bearing capacity of 300kg~1000kg/m2, and the columns are round tubes with strong bearing capacity and less steel; The main and secondary beams can be economically and reasonably H-shaped steel and C-shaped cold-formed beams according to the bearing needs.

　　The shelf floor of the attic is made of special C-shaped cold-formed patterned steel plate or hollow plate, which adopts gusset plate structure and is fixed with the main and secondary beam steel. The whole platform structure has strong integrity. Different floors can be selected according to actual needs to meet the requirements of fire protection, dust prevention and small parts fall prevention. The lighting system can also be configured under the floor as required.
