Black sheet and DKP sheet: key differences
Black sheet and DKP are trade names for different sheet categories. The general distinction is often between hot-rolled uncoated sheet and cold-rolled sheet; the exact definition should come from the product standard.
Manufacturing process
Hot-rolled sheet is produced by rolling steel at elevated temperature. Cold-rolled products are made by an additional cold-rolling step applied to hot-rolled strip.
The rolling route can affect surface appearance and dimensional control. It does not, by itself, define the material grade; multiple grades and standards may exist under similar trade names.
Surface and application
Hot-rolled products may have mill scale on the surface; pickled products have that layer removed. Cold-rolled products may be selected where a different surface or dimensional-control requirement applies. Actual performance depends on the specified grade and finish.
If painting, coating, bending or welding is planned, include those steps in the quote request. Product selection should not rely only on the words ‘black’ or ‘DKP’.
What to compare
- Product standard and grade
- Surface condition and additional processing
- Thickness and dimensional tolerances
- End use and forming requirements
