The early rise of storage shelves has evolved to date, consistent with the needs of modern warehousing, and has met the characteristics of various industries and has presented two large-scale evolutions. Early welding method shelves and today's assembled shelves are all in the category of storage shelves.
Welded shelves: The joints of the shelves are connected by welding. The finished welding warehouse has many consumables and high transportation costs. It can only be used in fixed production and cannot be transported.
Assembled shelves: The joints of the shelves are connected by bolts or bayonet. The assembled storage shelves have less consumables, and the transportation cost is low and convenient. Compared with the welded shelf, the assembled shelf utilizes the mechanically dispersed load-bearing principle to reduce the material cost of the shelf and reduce the transportation cost. For the user, the shelf can be disassembled and replaced at any time.
After undergoing changes in welding and assembly, the shelves were divided into two categories, fixed or mobile: mobile shelves and stationary shelves.
Mobile shelves are currently divided into: mobile shelves and rotating shelves. Mobile shelves are represented by light, medium-sized translating shelves and heavy-duty tray-type mobile shelves; rotating shelves represent horizontal rotating shelves and vertical rotating shelves.
Fixed shelves are the mainstream products commonly found in the market: laminate shelves, pallet shelves, attic shelves, through shelves, gravity shelves, cantilever shelves, mobile shelves, drawer shelves, steel platforms.
Over time, the shelf has been divided in height: low shelf, high shelf, super high shelf. All three shelves are custom made to the customer's storage environment.
Nowadays, the shelves are further divided into load-bearing weights under the planning of the manufacturers: light shelves, medium-sized shelves, heavy-duty shelves. With the advent of the information storage management system, there may be new types of future shelves.
