2. Automatic punching
It has a fully automatic continuous punching production line, which is used to complete the punching of the column profile before binding. The hole spacing accuracy can reach 0.02mm, and the cumulative error of the column length is not more than 2mm.

3. Cold rolled forming
The shelf column and various beams are bound by their own automatic cold bending forming unit, which is automatically positioned and cut according to the required length, and the length dimension error is not more than 1mm.

4. Welding
All are welded by carbon dioxide shielded welding machine, which ensures the quality of the weld and the smooth appearance of the weld.

5. Column
①Material: cold rolled steel plate;
②Color: blue (can be customized according to customer requirements);
③The column and the horizontal brace and diagonal brace are all connected by galvanized bolts;
④When fully loaded, the maximum deflection of the column is not more than 1/1000H;
⑤The bottom of the heavy-duty shelf column is equipped with a bottom plate, and the bottom plate and the ground are connected by expansion bolts to ensure the stability of the shelf;
⑥The total height of the rack column is determined according to the design requirements, the column hole distance is 50, 75mm, the layer height can be adjusted freely, and the cumulative error of the hole distance is ±1mm;
⑦Using convex column with optimized cross-section and strong load-bearing capacity; (Select bearing-bearing columns according to design requirements, commonly used columns: medium-sized columns 55*50, heavy-duty columns: 90*70/108*85).

6.beam
①Material: cold rolled steel plate;
②Color: orange (can be customized according to customer requirements);
③Each beam is equipped with a safety pin to increase the safety factor;
④ When the beam is fully loaded, its maximum deflection is not more than 1/200L;
⑤The beam and the column are connected by hanging teeth, which are inlaid without gap insertion, with large contact area and good reliability;
⑥Using cross beams or P beams, etc., with optimized cross-sections, strong bending resistance and load-bearing capacity; (the selection of cross beams is based on span and load-bearing options, conventional dimensions: welding beams are 80*45, 100*45, 120*45, 140*45,) .
