Common Quality Issues：

1: product wave edge or in the loose drum belly phenomenon: mainly the quality of the existence of the substrate. The predecessor of the substrate is rolled hard, due to uneven thickness caused by the phenomenon of the most waves, the other due to equipment problems less part of this is the actual reason, if the substrate is not wave edge after painting wave edge then the general situation is: the corrective deviation or the existence of other equipment is not normal operation caused by the phenomenon.

2: lines: products out of the back of the paint or back paint with paint leakage phenomenon in the industry is called: lines. Such a problem is generally every manufacturer is difficult to avoid the problem of impurities in the paint to occupy a part of the reasons for the equipment also has a part of the factors of the substrate also has a proportion.

3: product wrinkles: no problem with the equipment is generally the original presence of the substrate occupies a large proportion of the hot-dip galvanized steel folds mainly from the presence of galvanized production line technology and equipment failures caused by the general understanding of the galvanizing process of the friends will not be difficult to solve this problem.

4: from the appearance of the steel coil to determine the quality: the general appearance of the requirements of the winding neat, no burrs on both sides of the steel coil, jagged edges, obvious gap between the two sides of the phenomenon, this is the minimum requirements, but based on this alone is very difficult to determine the production of a variety of problems encountered.
