round hole perforated metal

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.

There are many categories of large coils of galvanized wire, and different categories can be applied to different scenarios. Galvanized iron wire common application is the application of the construction industry, one is the use of binding wire, whether it is the binding of scaffolding or reinforcement, need galvanized iron wire to carry out, the common specifications are 22 and 24 wire, common length of 30cm, 35cm, 40cm, 45cm, 50cm. There is also 20kg or 50kg a bundle of 18, 16, 14, 12, 10 galvanized coil wire.

Some large roll galvanized wire products in order to meet different industrial needs, will be further processed on the surface, such as the anti-corrosion layer, galvanized, iron plating, aluminum alloy plating, or in the galvanized wire appearance above the copper plating, brass plating, etc., to strengthen the steel wire and colloidal years and capabilities. Generally, galvanized wire products should be well plated and drawn when they are produced, and the sequence of the two processes should be decided according to the production or industrial needs.

Hook mesh is crocheted with silk heart, its mesh is uniform, flat net surface, beautiful and generous net width, thick silk diameter, not easy to corroded long life, weaving simple, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of mechanical equipment, highway guardrail, sports site fence, road beautification with protective net. The screen in the manufacture of a box-like container, with stone filled with the cage, can be used to maintain and support seawall, hillside, road and bridge, reservoir and other civil engineering.
