Specification and quotation of Jianliang metal steel plate mesh plastic coated wire manufacturer Cangzhou

  The common galvanized wire is divided into hot-dip galvanized wire and cold-dip galvanized wire (galvanized wire)
The difference is: hot-dip galvanized wire is dipped in the heated and melted zinc solution
The production speed is fast, and the coating is thick but uneven
The minimum thickness allowed in the market is 5 microns, and the maximum thickness can be more than 200 microns
The color is dark, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance
Hot dip galvanizing can be maintained for decades in outdoor environment / BR & gt; Cold galvanizing (electro galvanizing) is to gradually coat zinc on the metal surface through the unidirectionality of current in the electroplating tank
The production speed is slow, the coating is uniform, and the thickness is thin
Usually, it is only 3-15 microns, with bright appearance and poor corrosion resistance
It will rust in a few months
Compared with hot galvanizing, the production cost of electro galvanizing is low
They can be identified from the color
The cold galvanized color is shiny, silvery white and yellow The uniformity of zinc coating is an important quality index of zinc coating
Generally, the corrosion always starts at the thin part of zinc coating and extends around, resulting in corrosion and wire breakage, which affects the service life
For the weight and combination of coating, various standards have clear provisions, but the uniformity is different, 20th century , The hot-dip galvanized iron wire is made of high-quality low-carbon steel Q195 wire rod
The galvanized iron wire is divided into hot-dip galvanized wire and cold galvanized wire (galvanized wire)
Q195 is made of high-quality low-carbon steel through drawing forming, pickling and rust removal, high-temperature annealing, hot-dip galvanizing, cooling and other technological processes
The hot-dip galvanized iron wire has good toughness and elasticity, and the maximum amount of zinc can reach 300g / m2
It has the characteristics of thick zinc coating and strong corrosion resistance
