When working with Corten steel, a common challenge arises as end users prefer products without a protective layer, allowing the material to oxidize naturally and develop the highly desirable rich orange patina. They seek a smooth, residue-free, and uniform surface.

If this hard mill scale layer is not removed, Corten steel oxidizes very slowly in outdoor conditions. The patina appears inconsistently, breaking through the scale in random areas, resulting in a dark, uneven, and dirty-looking surface with visible flaking residue. Achieving full oxidation outdoors can take several months, and even then, the final result will not be as visually appealing as when the surface is properly prepared from the start.

Today, the most common method of mill scale removal is abrasive treatment (such as sandblasting, shot blasting, or grinding). However, these methods are often costly, inefficient, inconvenient, and risk damaging or deforming the product.

To address this issue, LineaCor has developed d-x COR, a revolutionary solution that allows manufacturers to prepare Corten steel for final use efficiently, without excessive financial or labor-intensive efforts. Many professionals recognize this as an innovative alternative to traditional abrasive treatments.

Additionally, d-x COR can also be used by end users who have purchased Corten steel products from less experienced manufacturers and want to ensure that their items are flawless, smooth, and free from factory residue.

When working with d-x COR, it is essential to carefully follow the process and safety requirements, reviewing all instructions and recommendations before use.
