P beam step beam roll forming machine for warehouse shelf
What is the P beam of shelf?
The goods shelf is made of the following elements: upright pillar, P beam, transverse braces, diagonal braces and self locking bolts. For the for the P beam, there are also two types, one is welding, the other is made by cold roll forming without pointing. Compared with point welding P beam, without welding type is not strong. So in the following part, I will take the point welding P beam for example. In the market, there are also some interlocked type P beam which the thickness should be within 1.2mm.
Hereare some drawing profiles of P beam for your reference:
About this drawing, you can use welding either continuous or spot welding to make it strong. And for the above type, it uses the interlocked type.
Questions about the P beam rolling forming machine: Whether many sizes could be made by one machine and how to make, if Yes.
The answer is Yes, if those profiles have some principle to follow. If you know how to adjust spacer, you can change those profiles by spacer. Meanwhile you need to change the cutting blade. But if you do not know how to change, you can use the fast change type.
By a rolling forming and closed welding; welding beam and column and according to hold the pass of different specifications, different collocation column card; 4 surface treatment: shelf surface adopts electrostatic spraying epoxy resin, coating thickness 60~80 micron; spraying process: surface decreasing, pickling, washing, washing, washing, drying, photostatting, high-voltage electrostatic spraying and high temperature curing; 5 production process: automatic punch punching, automatic rolling line, computer fixed length shear folding, CO2 welding, electrostatic spraying (this step according to different customers the color needs to choose different spraying color).
Features of this Point welding P beam roll forming machine:
- Working speed is around 5m/min including welding speed.
- Economic machine design plan but machine is quite strong.
- Dis shearing to make sure the P beam can keep perfect shape.
- Point welding can do at the same time of rolling forming.
