Design Criteria Of Mezzanine

- Jun 09, 2020-

1. Design standard

JB/T 5323-91 steel rack technical conditions;

ZBJ83015-89 code for design of high-rise warehouse;

Specification for design of FEM10.202 European material handling industry of steel racks;

2. Product features

Upright and H bracing, D bracing and the footplate are connected by bolts, bolts for high strength bolts 4.8 galvanized;

The whole beams punch forming, effectively prevent the severe impact, greatly improves the loading capacity;

The upright can be adjusted up and down according to the pitch. Each layer of the beam is equipped with safety pins, to prevent beam moving in work;

Molded by the factory by rolling, its rigidity, strength meets the standard of machinery industry;

3. Surface treatment

All the parts rack surfaces by cleaning and degreasing - after phosphating, then epoxy resin powder (PowderCoating), the thickness of the coating is 60~80 microns, and by a constant temperature of 180 DEG C, and use the 2H pencil test no scratches;

Electrostatic powder adhesion reached level 0 requirements in the GB92865-88 standard;

The hardness (wear resistance) is 100 times more than ordinary Xiaojiqi, reached 2 in the standard of GB6739-86 ii;

The corrosion resistance of GB1171-91 (hydrochloric acid experiment) is more than 500 hours.

4. Technical deviation

The upright bending error is less than 1/1000 or 10mm;

The upright and the installation of ground vertical deviation less than 1/1000 (ground roughness 1/1000);

The maximum load bearing measure deflection is less than 1/200;

The safety factor is not less than 1.65.

5. Strength instructions

The strength index profiles of the rack (N/mm2): tensile, compressive and flexural shear 205, 120, 310 end bearing;

The rack strength index (N/mm2): compressive weld butt weld tensile bending 120, 175, 120; weld compressive, tensile and bending 140.

6. Process

Production process: raw materials - cold rollingforming - length flat - punching (welding) - correction plane spraying packaging products
