Detection Content

Detection Purpose: Check the galvanizing amount of wire rope/strand

Detection range: Galvanized steel wire rope, galvanized steel strand

 Galvanized steel wire rope test:


Weight of galvanized layer shall be expressed as the average weight of galvanized layer per unit surface area, unit g/㎡.


There are two methods of galvanizing steel wire: continuous hot plating and electroplating. Electrogalvanization (see wire electrogalvanization) is obtained by external power supply, electrodeposition, the obtained coating is composed of fine pure zinc grains. Hot dip galvanized (see hot dip galvanized steel wire) is a physical thermal diffusion action to form coating, the first form of iron - zinc compound, one after another in iron - zinc compound surface of pure zinc layer. Theoretically, zinc coating of any thickness can be obtained by electrogalvanizing. At present, the amount of zinc on electric zinc plating can be up to 1200g/m2. , the amount of zinc on the general electric zinc coating can also reach 750g/m2. And the highest value of hot dip zinc zinc also only 593g/m2. Hot dip galvanized steel wire will reduce the mechanical properties, high strength and corrosion resistance requirements of high galvanized steel wire rope, the use of electrical galvanized steel wire twisting system.
