Friends in the industry know that galvanized iron wire has two kinds of cold galvanized iron wire and hot galvanized iron wire, so what is the difference between cold galvanized iron wire and hot galvanized iron wire? Which is good?

Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. Also known as: twist flower net, stone cage net, gabion net, flood control network.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

Fence use: generally used as a fence is a plastic-impregnated welded wire mesh with a height of 1.2 meters to 2 meters. Most of the mesh holes are 6cm, and the wire diameter varies from 2mm to 3mm.

Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.

If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.
