  • Tolerance range: radial mesh deviation range is not more than ± 4%, zonal mesh deviation range is not more than ± 3%; Solder joint tensile strength exceeds the national standard.

  • Appellation: Hook fence net is a variety of fence net. The diameter of the opposite side of each mesh is generally 6.5cm-14cm. The diameter of the wire used is generally from 3.5mm to 6mm. Wire material is generally Q235 low carbon wire. The iron wire is welded into black pieces of decorative hook mesh by ginning. The overall size of the mesh is 1.5 m X4 m, 2 m X4 m, 2 m X3 m. The general surface treatment is cold (electric) galvanized treatment. There are also hot dip galvanizing, dipping, spray. But overall, 99 percent is cold (electric) galvanized.

  • Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.
