The essential difference between hot dip galvanized steel wire rope and electro galvanized steel wire rope is that the zinc layer of hot dip galvanized is better than that of electro galvanized because of the zinc and iron alloy layer. Hot dip galvanized steel wire rope surface state because hot plated zinc iron alloy, so his color should be a little black. The electroplating surface does not have a chemical reaction, so it is still the natural color of zinc, which looks brighter. Under normal circumstances, the zinc layer of hot dip galvanizing is thicker and the corrosion resistance is better. The zinc layer of electrogalvanizing is relatively thin, and the corrosion resistance is poor. (Unless the zinc layer of electrogalvanizing also reaches the degree of thick zinc layer)
The following is the concern of our users, in the end is the electroplated steel wire rope good, or hot plated steel wire rope good? You can't generalize, depending on what you use for. For example, the support steel wire in the water pipe, or electroplating is better, good-looking, and the cost is low; If it is a power tower, it should be hot-dip galvanized. Because of the good corrosion resistance of hot dip galvanizing, it can be used for 30 or 40 years. Because the zinc content of the surface is high in electrogalvanizing, but because the surface of the hot-dip galvanized steel wire rope has a layer of zinc-iron alloy, its corrosion resistance is much higher than that of the cold-galvanized steel wire rope. At present, the market is generally electroplated steel wire rope, because hot plating is expensive, dealers sell hot plating profits are low, and the sale is good, but the corrosion resistance of electro galvanized steel wire rope in the air is a year and a half. But hot-dip galvanized steel wire rope anticorrosion ability is long. To distinguish from the appearance, the appearance of electro galvanized steel wire rope is brighter and more beautiful, but the appearance of hot-dip galvanized steel wire rope is black.
