There are two methods to clean spiral. The first is surface rust. Because the coil is produced using raw materials from iron and steel, and in the use of the process and ultimately will be the sun and rain, by this way, the spiral will appear rust corrosion phenomenon, so often on the coil surface rust It is essential. Another method is general cleaning, but can not use water wash, general cleaning mentioned here refers to professional decontamination solvent to spiral dust, but this can not be achieved rust cleaning function, but to cope with the ordinary dirt only.

Four reasons spiral wrong side:
The first problem is the docking, when the strip head and tail docking, if the welding seam height is larger than it must be careful attention, because if not handled properly at the time of molding, it is extremely easy to have a greater wrong side.
The second reason is the wrong side of the poor condition of the strip edges, so when you want to select high-quality selection of raw materials manufacturers to purchase guaranteed.
The third case, sometimes spiral when docked because of hard curved strip caused the wrong side, this phenomenon is due to the head and tail of the strip when not cutting edge shape and dimensional accuracy was poor due.
The last and most important point, that is, the camber of the strip. This is because the spiral in the molding, the strip camber is constantly changing in ay type angle, resulting in a difference weld cracks, and finally produce slits. In such a case, the quality spiral will be severely affected, we must adopt effective measures to control.
