The inertia of the column section, the thickness of the slab, and the inertial distance of the cross section determine the load-carrying capacity of the shelf. As the "pillar" of the shelf's spine, it has a decisive effect on the carrying capacity of the entire shelf.
In the case of shelf shelves (also called medium shelves) and heavy shelves, shelf shelves generally have four or four levels of shelf life, and their carrying capacity varies depending on the parameters of the columns. Specifications are 38*38 (mm) angle steel shelves, bearing capacity from 100-150 (kg).
Column specifications: 50*30 (mm), each layer of the carrying capacity of 100-250 (kg), suitable for storage of clothing and other goods.
Column specifications: 80 * 40 (mm), each layer carrying capacity of 200-400 (kg), suitable for storing daily necessities and other similar goods.
Column specifications: 55*47 (mm), each layer of the carrying capacity of 300-800 (kg), suitable for storage of light industrial products.
In daily production, the maximum number of shelves is 400 kg. Medium-sized shelves are generally used in electronics, auto parts, food, and medical industries.
Heavy shelves are less laminates than medium-sized ones, but their carrying capacity is several times stronger. There are usually four specifications for heavy-duty rack columns.
The pillar section is 80*60 (mm), the height of the pillar is less than 3.5m, and the upper limit of each layer is 2 tons. The total shelf capacity is 8 tons.
Column section 90*67 (mm), height of column up to 5.5m, with an upper limit of 3 tons on each floor, and an overall shelf capacity of 12 tons.
The pillar section is 100*70 (mm), the height of the pillar is less than 7m, and the upper limit of each layer is 3 tons. The total shelf capacity is 8 tons. (Column height is 7m, usually the number of shelves is five layers)
The column section is 120*95 (mm), the column height is 7m or more, and the upper limit of each layer is 2 tons. The overall shelf capacity is 20 tons.
Heavy goods can store a wide range of goods, basically covering electricity, industry, energy, clothing, food, and medical industries.
The column parameters of the above two shelves may indicate that the inertial distance of the pillar section and the length of the pillars of the medium-sized shelves and heavy-duty shelves determine the load-carrying capacity of the shelves. The greater the length and the inertial distance of the sections, the greater the carrying capacity. In addition, the increase in the thickness of laminates in medium-sized shelves (ie, shelf shelves) can also increase the carrying capacity of medium-sized shelves.
