Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.

The galvanized requirements of the parts to be plated: the surface of the parts to be plated should be smooth, and there is no dirt that cannot be removed by pickling method. Such as paint, grease, cement, asphalt and excessive rotten harmful substances; All welds of welded components shall be sealed without air; Pipe fittings and containers must have exhaust and zinc inlet holes; The workpiece should be finished welded steel pipe without thread, if any thread should be protected.

For single-layer wound non-rotating wire rope, it is necessary to strictly abide by the above principles, otherwise it is easy to cause permanent deformation of wire rope structure; In the case of multilayer winding, the rotation of the rope is determined by the orientation of the reel’s rope groove to lay the foundation for the next layer. The friction between the wire rope and the extrusion pressure of the multi-layer winding drum are large, and the disorderly rope phenomenon is easy to occur. Therefore, the wire rope with a diameter slightly smaller than the pitch of the rope groove and the diameter of the rope groove should be selected to add the touch area between the wire rope and the drum.
