Nowadays, consumers like to use iron guardrails. During the construction process, there will inevitably be welding slag and rust over time. So how to remove it? The main methods for removing rust and oxide scale welding slag from Nanjing iron guardrails include manual treatment, mechanical treatment, spray treatment, chemical treatment (pickling), electrochemical treatment and flame treatment.

1. Mechanical treatment Commonly used tools include pneumatic (electric) brushes, rust removal guns, polishing wheels and pneumatic (electric) shovels, etc., with the help of high-frequency impact and friction of mechanical force to remove rust and remove scale, old paint and other dirt.
