All of our bumper kits are laser cut from hot rolled P&O steel, not cheap mild steel. The laser cutting gives exceptionally clean, precise cut lines without any of the slag or roughness you get with plasma cutting. The P&O steel means the steel will be completely free of any surface rust and even more importantly there will be no mill scale. Mill scale requires sandblasting or another cleaning method to remove prior to welding and painting/powdercoating which adds cost and time for you. Our P&O steel is ready to weld right out of the box and only requires degreasing prior to painting/powder coating.
