corrosion resistant drywall screws

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.

Most builders buy hot-dip galvanized wire. They want good corrosion resistance. And people use galvanized wire products in their daily life, such as wire mesh guardrail, galvanized wire is more, which still takes into account the cost. In addition, galvanized silk will also be used in the field of art. Artists are attracted to its bright color and softness, so the factory must consider these factors when producing galvanized silk.

3. Straightening and cutting: straighten and cut the cold galvanized wire after drying to reach the set size and length.

Decorative hook mesh also has flexible characteristics can be used in different fields according to the needs of designers. When using hook mesh in corrosive environment, we must attach great importance to the selection of hook mesh parts materials. Now the hook mesh is often used in breeding fences, captive animals, protective gardens, etc., the wind and sun surrounding environment is difficult to ensure its life, some hook mesh in use for a period of time, due to exposure to the sun and humidity, will appear welding phenomenon, easy to shorten the service life.

Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.

According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:
