Pickling & oiling

Laura Metaal Staalcenter Maastricht has a unique continuous sheet pickling line that was specially developed for and with us. The quality of the outgoing material is unmatched.

Hot-rolled non-alloy and low-alloy steel is covered with a mill scale. This layer is undesirable for further treatments, in particular laser cutting. The best method for removing the mill scale is pickling. Pickling is a chemical cleaning method for metal surfaces, whereby the rust layer, the mill scale or an oxide scale is removed. For steel, the best results are achieved by pickling in hydrochloric acid.

After pickling, the material is extremely clean and smooth, which makes it more suitable for laser cutting. A light oil layer is applied to avoid rust.
