What is a galvanized wire?
Galvanized wire or white wire (Galvanized Wire) is; Galvanizing black wire (with a thickness of 1.2 to 4 mm) and with a length of about 3 to 290 meters per kilo by hot or cold method in order to add a series of features such as increasing life, easier use, increasing resistance to it. The reason for naming white wire comes from the fact that after galvanizing, a layer of zinc (in white color) is placed on the steel wire, but according to the hot or cold manufacturing method, the color of this product can be shiny (cold) or dull (warm). Is. It is necessary to remind that the price of hot and cold galvanized wire is different.
It goes without saying that this galvanizing operation on ordinary wire (black wire) has caused the application of this product to increase greatly and very quickly in industries. It can be used in various construction, industrial, etc. In general, we can say: galvanized wire is the same black wire that is covered with zinc metal. In this way, galvanization is said to be done in two ways, hot and cold. During the hot galvanizing process, steel without fat and oxygen is placed in molten zinc, and due to the reaction of steel and zinc (zn), an alloy coating of zinc covers the steel and protects it from corrosion, rust and adverse conditions. Protects the environment. This type of wire is called hot wire.
In the cold galvanizing method, molten zinc is not used, but zinc metal covers the surface of the steel by means of electric current and by electrolysis method and by means of electric current. In this method, the thickness of the zinc metal is less than the hot method, and as a result, the cold wire has less resistance than the hot wire.
Characteristics and difference between hot and cold galvanized wire
How to make galvanized wire in two different ways has caused the products to have different characteristics, we will describe them in the following. Dad:
The method of making hot galvanized wire is by using heat and passing the wire through a zinc bath, but in the cold method, zinc is placed on the wire by electric current.
The type of hot wire has a higher resistance than the type cold, the reason for that is the difference in its production process.
Hot galvanized color is more transparent, cleaner and shiny than cold.
The expiration date of hot galvanized is more than 70 years. After a short period of time, cold will peel off or the part on it will be separated from the wire.
The price of hot galvanized wire is higher than cold.
The application and use of hot galvanized wire is much more than the It is cold. "Galvanized wire has different sizes in the range of 0.5 to 2.8 mm and is used in construction, reinforcement, agriculture, poultry farming, decorative items, fencing, scooping, rabbiting, greenhouse, etc.
Due to the greater thickness of zinc metal (zn), hot galvanizing has a higher price compared to cold galvanizing." In general, if you are an expert in this field as a civil engineer or builder, you can distinguish between these two products just by their appearance.
