As the most cost-effective alternative, uncoated strapping is cold-rolled and the edges are deburred, not rounded. There is no corrosion protection and the strength is in the range of about 700 N/mm² and the elongation is about 3%.
Depending on the rust protection, you can distinguish between three strapping qualities: blued, black lacquered and zinc-coated, in order of the respective corrosion protection. All quality strapping is waxed to ensure the best possible processing with steel strapping tools. Depending on the thickness of the strapping, the strength is about 850 N/mm² and the elongation is about 6-8%.
High-performance steep strapping has the highest values of tensile strength and elongation – 1050 N/mm² at approx. 12-14% elongation.
The different quality classes are used depending on the requirements. In the case of hot-coil strapping, for example, blued steel strapping is sufficient. In the pipe industry, a clear trend towards PET strapping has become apparent in recent years. For example, PET is very suitable for affixing coils on the means of transport or also in the processing industry, such as cold rolling mills. Our PET strapping is very popular in the 25 mm width for particularly high tension forces, whether for use in fully automatic machines or with battery-powered strapping tools.
