Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

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.

4, safety, environmental protection, harmless to people (livestock), even if it does not intend to touch the guardrail will not hurt like steel, iron guardrail. Stainless steel wire mesh can be used as poultry cage, egg basket, channel fence, drain tank, porch guardrail, anti rat net, mechanical protective cover, livestock and plant fence, grid frame, etc.
