The angle steel frame is mainly composed of columns and steel laminates. It is suitable for manual access to lighter goods. It can be used with plastic turnover boxes to store many kinds of small products. It is widely used in the electronic industry and small parts warehouse. It can realize the anti-static function by changing plastic spraying powder or laying special rubber plates. It has the characteristics of low cost, safety and reliability, simple assembly and disassembly. It can be used alone or freely spliced into various arrangement modes. Adding a universal wheel mechanism at the foundation can even realize the transfer function. The top and bottom layers of the shelf are connected with the column with double corner codes and screws to make the shelf stable. The steel laminate is made of Japanese standard SPCC cold plate, which is bent on four sides according to the required size, and the concave stiffener is welded below. Spot welding is adopted for welding. This structure has the characteristics of material saving, good bearing condition and smooth surface.

1. Shelf column: it is made of equilateral angle steel with bilateral punching. The hole distance is arranged in a straight line with a distance of 50mm. The column hole is used to hang the laminate;

2. Shelf steel laminate: adopt cold-rolled steel plate and bend four sides according to the required size.

3. The upright post and the steel laminate are connected and fixed through quick snap pins and triangular fixing pieces.

4. After all parts of the shelf are processed and formed, the finished products are assembled after grinding, pickling, phosphating, automatic powder electrostatic spraying, drying and other processes. The surface of the finished shelf products produced is smooth and beautiful; The laminate can be adjusted up and down freely, which is convenient for disassembly and assembly.
