Sheet steel: products, production and areas of application
Sheets and flat products are finished products made of metal that are usually produced and rolled in complete sheets. We offer you coils, slit strips and cold-rolled strips, as well as cover sheets, thin sheets, heavy plates, perforated sheets and galvanised thin sheets.
What is a thin sheet?
In contrast to heavy plate, thin sheet is usually cold-rolled into shape after the hot-rolling process. In addition, the material thickness of thin sheets does not exceed three millimetres.
What is heavy plate?
Heavy plates or quatro plates are usually only hot-rolled. They refer to sheets with a material thickness of three millimetres up to 200 millimetres.
Where are steel sheets used?
The range of applications for sheet steel is very diverse. They are often used as cladding for building components – for example as façade elements for high-rise buildings. But they are also often used in the automotive industry, in shipbuilding or in ventilation systems.
How are steel sheets manufactured?
Sheet steel is produced using the so-called hot rolling process and then cold-rolled into shape if required. During hot rolling, steel ingots are heated and reduced and stretched to the required thickness by applying pressure in the mill’s rolling gap.
If necessary, the sheet can then be cold rolled. In this process, the sheets are reduced to an even thinner thickness at room temperature.
Special feature of galvanised sheet steel.
Galvanising gives steel sheets corrosion protection, which even provides active protection in a damp environment through a redox reaction. All galvanised steel sheets from SÜLZLE Hagmeyer are galvanised using a hot-dip process. In this coating process, the sheets are completely immersed in a bath of molten zinc. They form a solid bond through mutual diffusion, creating an inseparable iron-zinc alloy in the coating.
