1 1 4 hot dipped galvanized roofing nails

It is generally believed that the positive and negative twisting wire wire is not as durable as the thickness, common sense thinks so, but the positive and negative twisting wire wire is used in hot galvanized steel wire, which is more than 3 times the tensile strength of the iron wire, and the zinc amount is not lower than the hot plated wire

③ The galvanized iron wire shall not be damaged when it is tightened.

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.
