Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

The main raw material of blade barbed rope is galvanized wire and galvanized sheet, because the price of galvanized sheet is more expensive than galvanized wire, so it is directly reflected in the price of the sales of blade barbed rope. There is also the difference in processing technology also led to the difference in the price of the blade thorn rope. The traditional barbed rope is mechanically twisted, which uses less labor and has high production efficiency. But the blade is after two mechanical processing in the manual processing operation before the appearance. So whether from the labor force or from the production efficiency also said there is a large gap. These factors lead to the price of blade thorn rope is more expensive the main factor.

There are too many fake things on the market now, so shoppers should learn how to distinguish the quality of galvanized wire, the right to protect their consumers’ rights and interests. Galvanizing process of galvanized wire products is a very effective metal anticorrosion method, and it is also widely used in other industrial fields. After galvanizing, iron wire is commonly used in metal structure equipment of various industries.

The term “wrought iron” often gets misused today to refer to any metalwork – often mild steel or cast iron – that’s designed to have the precise, intricate appearance of the classical wrought iron designs from the nineteenth century. However, to truly be wrought iron, the metal has to have been forged, heated, and hammered by a trained blacksmith, a process that’s become much rarer today than it was in the past. The hand craftsmanship that goes into its design and construction makes wrought iron a truly unique and special material today.

This creates a more affordable product that is easier to work with, but still displays similar properties to that of genuine wrought iron.
