1.With reference to pre galvanized steel pipe, before the zinc repair in the welding, we will first set out to remove the welding slag, zinc oxide skin and burned out layer. Then we use the spray painting for the repair of the zinc layer. We have the zinc repair in the welding close to the whole weld body in color, as a result of little color difference. Our finished galvanized pipe looks like much nature itself without blemish .
