The quality of raw materials is the basis for the success of galvanized iron wire
The quality of raw materials is the basis for the success of hot-dip galvanized wire! The galvanized wire is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel, which is processed by drawing, pickling and rust removal, high temperature annealing, hot-dip galvanizing and cooling.
Galvanized wire is further divided into hot-dip galvanized wire and cold-galvanized wire (galvanized wire). Common galvanized wire is divided into hot-dip galvanized wire and cold-galvanized wire (electro-galvanized wire). The difference is: hot-dip galvanized wire is immersed in hot melted zinc liquid, the production speed is fast, the coating is thick but uneven, the market The minimum allowable thickness is 45 microns and can be up to 300 microns or more.
The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. The hot-dip galvanizing in the outdoor environment can be maintained for several decades.
The surface of the coating of a good galvanized wire product is continuous and practical and smooth. The installation of the plated parts is not sag, dripping or slag is present, and the surface of the plated part should be free of defects such as leakage plating and iron.
Note (allowing for defects): The area of the plating area is less than 0.5 mm in diameter; regardless of the size of the plated part, the spot area of the plating area is 0.5-1 mm in diameter, not more than 3 points per square centimeter, and is plated. The total number of spots of the piece does not exceed 10 points;
In the unjoined or non-joined area, the sag or slag of not more than 1.5 mm in height; the contact between the plated parts and the hanger and the operating tool is not damaged.
For the adhesion of standard galvanized wire coating, the zinc layer of the plated part should be firmly bonded to the base metal and have sufficient adhesion strength. It does not fall off after the hammering test and does not bulge.
