Hot galvanizing is the first steel pipe for pickling, in order to remove the surface of the steel pipe ferric oxide, pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank.Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life
Building steel pipe has been widely used in Construction projects, civil chimneys, central air conditioning pipe, fences, threading pipe, greenhouse canopy (trellis tube), roller shutters doors, light steel keel, supporting tube, furniture, sports equipment, tents, guardrail etc.
