Medium-sized storage shelves are usually cross-beam laminated structures, and the height of each floor can be freely adjusted in units of 50mm-75mm. Wuhu Kojie medium-sized warehouse shelf column, laminate, beam three major components are selected high-quality steel. After phosphating, pickling and other pretreatment processes, the surface was sprayed with high-light electrostatic powder and baked at 180 degrees high temperature. The product is bright and beautiful. The surface has the function of anti-rust and wear resistance.

1. Introduction of Medium-sized Storage Shelf
Medium-sized storage shelves are one of the many brands and specifications of industrial shelves. They are generally divided into standard and non-standard types.
1. Standard type: beautiful appearance, easy installation and disassembly (75mm pitch adjustment) bearing capacity of 100~350; 2. Non-standard type: characterized by large span and large load, 75 mm pitch adjustment appearance novel, bearing capacity of 300~1000.
Medium-sized shelves are strong and bearing capacity is large. Medium-sized shelves are widely used in shopping malls, supermarkets, enterprise warehouses and institutions.
Usually it is divided into medium A type shelves, medium B type shelves and medium C type shelves. Generally, it can be assembled and disassembled, and the height of the laminates can be adjusted; the load-bearing layer bears 200-800 kg; all metal parts of the shelf are treated with rust prevention, and the appearance is electrostatic sprayed; the medium-sized shelves are suitable for storing goods in large and medium-sized warehouses.

2. Characteristics of Medium-sized Storage Shelf
1. The three-dimensional structure can make full use of the warehouse space, improve the utilization rate of warehouse capacity and expand the storage capacity of warehouse.
2. Easy access to goods, first-in, first-out, 100% selection ability, smooth inventory turnover;
3. The goods in the warehouse shelves are clear at a glance, which facilitates the important management work of inventory, division and measurement.
4. To meet the needs of storage and centralized management of large quantities of goods and varieties, and to cooperate with mechanical handling tools, the storage and handling work can also be orderly.
5. The goods stored in the shelves are not extruded and the material loss is small, which can completely guarantee the function of the material itself and reduce the possible loss of the goods in the storage link.
6. To ensure the quality of stored goods, measures such as moisture-proof, dust-proof, theft-proof and damage-proof can be taken to improve the storage quality of materials.
7. To meet the management needs of low-cost, low-loss and high-efficiency logistics supply chain of modern enterprises.
8. With the development of modern industrial civilization, the structure and function of storage shelves are constantly improving.

3. Types of medium-sized storage shelves:
According to the weight of the shelves, we divide the medium shelves into two kinds:
1. Medium Shelf A
Medium-sized shelves are mainly composed of pillars, beams, pallets and laminates. The main features are bolt-free connection, easy assembly and disassembly (only rubber hammer is needed to assemble/disassemble), beautiful and generous appearance, suitable for manual access to goods, bearing capacity is usually 200 KG-400 KG/layer, which can meet most of the requirements of use. The main parts of medium-sized shelves are made of cold sheet metal, which can be adjusted up and down freely according to 50mm spacing. In order to facilitate the operator to access the goods, the total height of shelves usually does not exceed 2 meters. If using the climbing equipment, the height of shelves can reach up to 3 meters. It can be used alone or spliced freely into various arrangement modes.
2. Medium shelf B
Medium-sized shelf B has a maximum of 3 meters. The effective standard load of each floor is 500-800kg. The column specifications are 55*47*2.0mm special shelf columns with high quality profiles. Medium-sized shelves are assembled with pillars, crossbeams, crossbeams, diagonal braces and self-locking bolts, which can effectively prevent the instability of the shelves caused by loosening bolts; the beams are made of special cold-rolled P-shaped closed beams, which are simple, reliable, light in weight, strong in bearing capacity and low in cost; and special design safety pins are equipped when the pillars are connected with the pillars to ensure that the beams are not subjected to external impact. The laminates are strip laminates, which are popular in the world. The thickness of the laminates and the number of reinforcing bars determine the loading requirements. They have the characteristics of strong bearing capacity, wear resistance, simple replacement and low maintenance cost. Medium-sized shelf B can be arranged freely in the form of main and auxiliary shelves; can use the stability of medium-sized shelf B to build attic shelves; suitable for manual access, or with parts boxes, turnover boxes supporting the loading of scattered heavy goods.
