Flat steel products, known as black sheet metal, are available on the market as materials that are heated to a certain temperature range and rolled after being cast into rectangular sections.

In the production of black sheet metal, the sheets are directly converted into rolls in the post-production stage to save space. The main difference between black sheet metal and DKP sheet metal is their color.

The thickness of black sheet metal ranges from 1.5 mm to 20 mm, making it generally thicker compared to other types of sheet metal.
