Stainless steel slotted angle are mainly composed of pillars and steel laminates, which are suitable for manual access to lighter goods. They can cooperate with plastic turnover boxes to store many kinds of small products. They are widely used in electronic industry and small parts warehouse. They can realize anti-static function by changing spraying powder or laying special rubber plates. They have the characteristics of low cost, safety and reliability, simple assembly and disassembly, and can be separated. It can also be freely spliced into various arrangement modes. Adding universal wheel mechanism at the foot can even realize transporting function. The top and bottom boards of the shelves are connected with the posts by double-angle codes and screws to make the shelves stable. The steel laminate is bended by the Japanese standard SPCC cold plate in four sides according to the required size and welded with concave reinforcement bar. Spot welding is adopted to weld the steel laminate, which has the characteristics of saving material, good load-bearing condition and smooth surface. 1. Shelf Column: It is made of double-sided punching of equal-angle steel. The holes are arranged in a straight line at a distance of 50 mm. The holes of the column are used to connect the laminates.2. Shelf steel laminates: cold rolled steel sheets are formed by bending four sides according to the required size.3. A rack consisting of a column and a steel laminate is connected and fixed by a quick buckle pin and a triangular fixing piece.4. All parts of the shelf are processed and processed by grinding, pickling, phosphating, automatic powder electrostatic spraying, drying and other processes to assemble the finished products. The surface of the finished shelf products produced is clean and beautiful, and the laminates can be adjusted up and down arbitrarily, so it is convenient to disassemble and assemble.
