KEMPER has a wide range of delivery methods:
The most common delivery method is rings. Particularly long wire lengths are achieved when the strip ends are welded together and the strip is either coiled or made as a POLYCOIL®. POLYCOIL®s can be processed on disc reels without any additional downtime caused by loops being changed.

When profiling the strips by milling or peeling, it is possible to have different material thicknesses in one strip. This allows various functions to be implemented:
In many instances, the stamping, embossing and bending costs can be considerably reduced by using a profiled strip. Depending on the demands on the material and the dimensions, KEMPER peels the material in-house or has it milled at Profiltech Stufenbandprofile GmbH, a sister company of the KEMPER Group. Profile strips are characterised by:
The demands on rolled strips in industrial processing are continuously increasing, which is why metallic surface coating treatments are frequently required. KEMPER has its own hot-dip tinning process in which the metal strip is drawn through a tin bath. Electroplating is available upon request at partner companies.
All hot-dip tinning variants are lead-free and are characterised by the following key features:
KAT® is a hot-dip tinning with increased hardness and improved abrasion resistance. These properties are achieved through a specific combination of the tinning process and the rolling steps.
