expanded metal mesh panels

Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.

When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
