Medium B shelf is also called medium B shelf, medium B shelf. Medium B shelf is unique in shape and beautiful in appearance. It adopts the structure of connecting pillars and beams, all of which are plug-in combination. It is simple in structure, convenient in installation and disassembly. The cross beam has a height of 50mm pitch adjusting layer, and is suitable for the case of large load-bearing capacity and long cross beam.

1. Brief Introduction of Medium B Shelf
Medium B shelf has 250-800kg load per floor. It is used for manual access of goods. It has the characteristics of low cost, safety and reliability, simple assembly and disassembly, and can be used alone, and can also be freely spliced into various arrangement modes. The two pillars of the sub-heavy shelf are connected by nylon self-locking bolts, which can effectively prevent the shelf from losing stability after loosening the bolts. The cross beam bar adopts a special cold-rolled P-shaped closed beam, which has the characteristics of simple, reliable, light weight, strong bearing capacity and low cost. Medium-sized shelves are equipped with special design safety pins when they are connected with the columns; it can ensure that the beams do not fall off after the impact of external forces; the most popular strip laminates in the world are adopted, and the medium-sized shelves have the characteristics of strong bearing capacity, wear resistance, simple replacement and low maintenance cost.

2. Characteristics of Medium B Shelf
1. Medium B shelves are used in various industries with low cost, safety and reliability, simple assembly and disassembly. They can be used alone or arranged freely in the form of main and auxiliary shelves.
2. The pillars of the middle B shelf are connected by bolts with pillars, cross braces and diagonal braces. The shelf frame is formed by inserting column sheets and P-shaped closed beams. The shelf frame is fixed by safety pins, and the structure is simple and reliable. The steel laminates are placed above the beams to form the whole shelf. Each layer can be adjusted freely up and down with 50mm step distance.
3. Medium B shelves can determine the loading requirements with the size of beams and thickness of laminates, and the number of reinforcing bars. When the relative length and material selection requirements meet, the maximum loading can reach 800kg/floor.
4. In general, the height of the column is not more than 3 meters, and the attic shelf can be built on the basis of the shelf.
5. The advantages of medium B shelf: low cost, strong bearing capacity, wear resistance, simple replacement, low maintenance cost, so that you can use high-quality products at low cost.
