General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.

  • The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.
