1. A Brief Introduction to Loft Storage Shelf
Loft storage shelf, a kind of shelf suitable for storing various types of goods, can make full use of the storage height and make better use of storage space.
Medium-sized shelf or heavy shelf shelf are usually used as main support and floor slab (according to the total load weight of shelf unit to decide which shelf to choose). Cold-rolled profiled steel floor slab, pattern steel floor slab or steel grille floor slab are usually used for floor slab. In recent years, cold rolled section steel floor has been widely used. It has the advantages of strong bearing capacity, good integrity, good load uniformity, high accuracy, flat surface, easy locking, etc. There are many types of optional, and easy to match the lighting system, access and management are more convenient. The load of each floor of the unit shelf is usually less than 500 kg, the space between floors is usually 2.2 m~2.7 m, and the height of the top shelf is generally about 2 m, which fully considers the convenience of staff operation.

2. Production Technology of Loft Storage Shelf
Attic shelves are divided into medium-sized attic shelves and heavy attic shelves.
Medium-sized attic shelves: Medium-sized shelf columns are used in shelf infrastructure. The shelf floor adopts the loft shelf special floor, and the floor adopts the interlocking structure. A supporting beam is erected under the floor.
Medium-sized attic shelf column specifications are: 55 x 55 x 1.5mm special shelf column profiles. It is made of high quality strip by leveling, rolling by automatic rolling mill, punching by punch and cutting according to the specified height of customers. Column brackets and connecting beams are formed by bending and punching high-quality cold plates.

3. Loft Storage Shelf Structure
The specification of heavy-duty attic shelf column is 80 *60 *2.0mm special heavy-duty shelf column profile. It is made of high quality strip by leveling, rolling by automatic rolling mill, punching by punch and cutting according to the specified height of customers. Cold-rolled P-shaped closed beams are used for crossbeams. The specifications are: 50 *30, 64 *40 and 80 *50. It is a standard product for shelf production in cold bending industry. After purchasing, according to the size of customers, the welding rack is connected with the special column grasp, and the grinding can form a semi-finished product.
After the production of all shelf parts, the last shot blasting machine is required to remove oil, rust and surface spraying. It can be packaged and shipped after completion.

4. Classification of Loft Storage Shelf
There are many kinds of storage shelves, according to the load of shelves, shelves are divided into light shelves, medium shelves, heavy shelves; according to the height of shelves, shelves can be divided into low shelves, middle shelves, high shelves; according to the form of shelves, shelves can be divided into channel shelves, dense shelves, rotating shelves.

5. Characteristic of Loft Storage Shelf
1. Loft shelves can increase shelf height, make full use of storage height, and make better use of storage space.
2. Paving special floor for shelves on the floor of attic racks has the characteristics of strong loading capacity, good integrity, uniform loading, flat surface and easy locking compared with pattern steel plate or rigid grille.
3. Attic shelves fully consider the humanized logistics, beautiful design, generous structure. Easy installation and disassembly, flexible design according to the field.
4. Loft shelves are suitable for storing various types of goods.
