Metal Plate Rust / Paint / Weld Mark Removal
Metal plate rust removal, paint stripping and weld mark cleaning are vital surface pre-treatment processes before coating and post welding, widely used for carbon steel, alloy plates, structural sheet metal and engineering machinery panels.
Long-term storage leads to rust and mill scale on metal plates. Incomplete removal of old coatings, welding slag, weld discoloration and thermal oxide will cause poor paint adhesion, blistering and peeling, and weld zones are prone to premature corrosion.
This process balances removal efficiency and substrate protection. It strips heavy rust and aged coatings rapidly without excessive stock removal or deep scratches, and weld blending requires smooth transition between weld bead and base metal.
Lean Abrasives’s high-precision sanding belts, flap wheels and sanding discs suit both continuous plate lines and single-piece grinding. Zirconia abrasive delivers strong cutting power; coarse grit removes heavy rust, old paint and raised weld beads quickly, while fine grit smooths weld marks and forms a proper anchor profile for coating.
Our non-woven polishing brushes and nylon roller brushes offer controlled flexible cutting, ideal for light rust, residual paint spots and weld oxide removal. They grind evenly and gently without gouging thin plates, and matching polishing wheels are available for fine finishing after welding.
Cup grinding wheels and diamond grinding wheels handle heavy oxide scale on high-hardness plates with aggressive grinding. Scouring pads, sanding paper and abrasive discs are suitable for small-area manual touch-up.
