  • Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.

  • Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.

  • No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.
