What material is the main material used in storage shelves?
Regular shelves are used in cold rolling, used this kind of steel to ensure the nominal load layer, but if other steel, or for complex steel, even with iron (really seen, I just saw it said, is actually a look at the iron shelves in the real factory, so thick. Thick are outrageous, the removed), then thick line.
Ordinary shelves, everyone saw the column is C type, also known as C steel, the shape of the advantages of easy processing, simple, processing costs cheap, all low cost, low load shelf like. But this shape is not used in heavy shelves, and now many enterprises are using it again for the sake of cost, which is not responsible. Because the C steel structure can be used in light weight, but the large load is not suitable, but should be replaced with a more reasonable structure of U steel. All large warehouses use columns of type U steel, especially all heavy duty shelves, on shelves over 1 tons. In fact, the shelves should also be used U export this structure is safe, and now look at those online sales of goods shelves, I saw a medium-sized shelf with the post, U port is the Hercules is C port, the other. Of course, U mouth than C mouth cost much higher, in the same thickness case, use steel quantity to one-third, carrying weight more than twice. Medium shelf is Hercules is 0.8 (light steel plate thickness is not painted, painted about 1.2 thick) U export shelves, with the same thickness of 0.8 C type export shelves, steel consumption to a third more (because U export processing cost is high, so the cost should be twice higher than for C about 80% high cost, export). But the load should be more than twice as much. Therefore, the U type is double the C load at the same thickness of the steel.
There is a section size effect layer load (the word is referred to as the bearing of each layer), the same thickness of 1.5mm P beam (shelf beam), to load a lot higher than 60*40 80*50, the 200 longest shelf as an example, the 80*50 layer load can reach 900 kilograms, and the 60* 40 layer contained only 400 kg.
Generally speaking, the more thick the steel of the shelves, the greater the weight of the load, but it is not blind, to increase the thickness is good. After all, the thickness increases, the cost will increase, and to a certain thickness of the thickness of the load is not so obvious as the beginning of the increase, but to use the design of the shelf shape changed.
