With the development of modern enterprises, attic shelves are becoming more and more popular among enterprises. I believe that most customers already know about the purchase, installation and maintenance of attic shelves, so how much do you know about the professional knowledge of attic shelves ?

In order to help everyone better understand the attic shelf, the following Dingli editor will analyze some professional knowledge about the attic shelf for you.

1. Design standards

1, JB/T 5323-91 steel structure rack technical conditions;

2, ZBJ83015-89 high-rise rack warehouse design specification;

3, FEM10.202 European Material Handling Association Steel Structure Shelf Design Specification;

2. Product technical characteristics

1. The column and the horizontal brace, diagonal brace, and bottom plate are all connected by bolts, all bolts are grade 4.8 galvanized high-strength bolts;

2. The beams and pendants are stamped and formed as a whole, which effectively prevents violent impact and greatly improves the load-bearing capacity;

3. The column can be adjusted up and down according to the pitch. Each layer of beam is equipped with safety buckles to prevent the beam from moving during work;

4. The forming parts are all rolled by Dingli factory, and their rigidity and strength are in line with the industry standards of the Ministry of Machinery;

3, surface treatment

1. All parts and components of the shelf are derusted, degreasing and phosphated, and then treated with epoxy resin electrostatic powder coating (Polyerter Powder Coating). The coating thickness is 60~80 microns, and they are dried at a constant temperature of 180°C. Use 2H pencil to test without scratches;

2, the adhesion of electrostatic spray powder meets the level 0 requirement in the standard of GB92865-88;

3, the hardness (abrasion resistance) is more than 100 times that of ordinary nitrocellulose paint, and meets the 2Ⅱ requirements in the GB6739-86 standard;

4. Corrosion resistance (hydrochloric acid test) GB1171-91 is greater than 500 hours.

4, technical deviation

1, the bending error of the column piece is less than 1/1000 or 10mm;

2, the vertical deviation between the column and the installation ground is less than 1/1000 (when the ground flatness is 1/1000);

3, the deflection measured when carrying the maximum load is not more than 1/200;

4, the safety factor is not less than 1.65.

5, strength description

1, the strength index of the shelf profile (N/mm2): tensile, compressive, bending 205, shear 120, end face pressure 310;

2. The strength index of the shelf weld (N/mm2): butt weld compression 120, tensile 175, and flexural 120; fillet weld compression, tensile, and flexural resistance 140.

6, process flow

1. Manufacturing process: raw materials-cold rolled forming-fixed-length flat head-punching (welding)-correction-plane spraying-packaging-finished product.

The above is some professional knowledge about custom attic shelves compiled by Dingli editor for everyone. I hope to help you better understand attic shelves.
