Cold rolled stripsteel
Cold-rolled sheet is a rolled/hot-rolled product that has a final process where the sheet is rolled in a cold state. The process requires rolling under high pressure and gives a fine and smooth surface with fine tolerances compared to hot rolled products. A cold rolled sheet can also be rolled thinner than a hot rolled sheet. Cold-rolled sheet is available in thicknesses from 0.3 to 14 mm.
Livallco Stål specialises in extra thick cold rolled sheet metal. Normally, cold rolled sheet is manufactured in thicknesses up to 4-5 mm, but we specialise in cold rolled sheet up to 14 mm thick. Normally, sheet metal over 4 mm is produced as hot rolled sheet metal. With cold-rolled sheet metal, you can achieve the right thickness tolerance directly without the need for extra processing. This avoids expensive processes such as milling and grinding.
Cold rolled extra thick plate is produced in most steel grades, such as structural steel, hardenable steel, spring steel, carbon steel, boron steel, high strength steel and key steel.
As of 2023, we can also supply cold-rolled sheet metal that is hardened directly at the mill, which offers both economic and environmental benefits.

The strip plate is fed through different pairs of rollers to the desired dimension.
Cold rolling starts with a hot rolled and pickled sheet or coil.
The strip plate is fed through a number of rolling pairs where it is reduced step by step down to the desired dimension. Between the different rolling processes, the plate may need to be tempered in order to be further reduced.
In the final stage, the strip/plate is annealed and edge trimmed to give the desired properties.
Livallco offers cold-rolled strip in steel grades that are not usually available from wholesalers.
Livallco supplies cold-rolled sheet in steel grades that are not normally stocked or produced by Swedish wholesalers and service centres. We also offer cold rolled sheet/ strip in thicker dimensions than normally offered.
Do you need high quality steel with flexible product dimensions in both width and thickness? At Livallco, we quickly deliver cold rolled steel strip as both plate and coils to your business.
In addition, the fine surface texture and tight tolerances mean that you often don't need to sand or mill the surface.
Coils are delivered in rings with inner diameter 500 mm and max. 2000 mm in outer diameter.
