Medium shelf, a kind of storage shelf, shelf shelf type. According to the bearing capacity of the shelf to distinguish and named. According to this division principle, the medium-sized shelf is between the light shelf and the heavy shelf, and the shelf usually carries 150kg/-500kg layer (calculated by the load capacity of the layer as a unit).Medium shelf standard type beautiful appearance, wide application, easy installation and disassembly, 75mm pitch adjustment, bearing in 100㎏~350㎏; Non-standard large span large bearing capacity, 75mm pitch adjustment appearance novel, bearing capacity of 300㎏~1000㎏. 

Medium-sized shelves are solid, bearing capacity is large, medium-sized shelves are widely used in shopping malls, supermarkets, corporate warehouses and institutions. It is divided into medium A-type shelves, medium B-type shelves and medium C-type shelves. Generally can be disassembled combination, layer height can be adjusted; Weight bearing layer bearing 200-800 kg; All metal parts of the shelf are treated with rust prevention and electrostatic spraying. Medium-sized shelves are suitable for large and medium-sized warehouses to store goods. In practical application, it is divided into middle A type shelf and middle B type shelf.

No bolt design, easy installation, reliable structure. The use of steel laminates, columns, beams, the entire shelf does not use bolt connection, easy to install and disassemble. Adopt the main and auxiliary connection form, strong stability. 

Middle A shelf features

easy to install, using bolt connection, with the main and secondary connection form, with stability. 

The top, bottom, frame connecting rod, column tray, chip and plug-in of medium shelf are all fixed with pins, easy to operate. 

Maximum load of load-bearing strength under relative length of 300kg/ layer. 

The laminates can be adjusted up and down freely at 50mm spacing. Shelf surface rust, spray treatment. 

The surface color can be selected according to customers, and the shelf is beautiful and durable. 

Pillar A is 55×5.5×1.5 mm. 

Using high quality steel mill automatic punching open, cut off according to the height specified by customers. 

The connecting rod of the column tray is made of high quality cold plate bending and stamping. 

The sheet is reinforced by high quality cold plate (SPCC), slabbing, opening bending and welding. 

No bolt connection, simple assembly and disassembly, beautiful appearance, and can be assembled multi-layer rack.

The middle B shelf adopts cooling plate Q235 steel (SPCC). Use beams and columns with inserts and put beams in frame form. Human receiving is applicable. B-type medium-sized shelves are used in various industries, low cost, safety, reliability, assembly and disassembly are very simple. Can be used alone, can also be used in combination with the main and auxiliary frames. Medium type B shelf features: medium shelf B column and diagonal brace are connected by bolts, column and P-type steel silent beam plug and socket to form the shelf frame and safety pin fixed, simple and reliable structure. 

Each layer of the shelf can be adjusted to a distance of 50mm. The height of the B-type shelf is not more than 3 meters, the specifications of the column are: 55 * 2.0mm, the special shelf 47mm, the automatic punching of the high-quality steel mill, according to the height and cutting specified by the customer. The beam adopts cold-rolled P-type, specifications: maintain 50×30× 40,64,80, 50 three specifications.

The load of each layer of the unit shelf is between 100-500kg, and the total load is generally not more than 2500KG. The shelf span of the unit is not more than 2.6m, the depth is not more than 1m, and the height is within 3m. If the unit shelf span is less than 2m, the layer load is less than 500KG, usually choose beamless medium-sized shelf shelf; If the unit shelf span is more than 2m, it is generally only possible to choose a beam type medium-sized shelf shelf. 

Compared with the beam type medium-sized shelf, the layer spacing can be adjusted more, more stable, beautiful, better coordination with the environment, and more suitable for some warehouses with high cleanliness requirements; Beam type medium-sized shelf shelf is more industrial characteristics, used to store metal structure products.
