Strapping tools for steel strapping are in many ways the sturdiest version of this kind of device, because they are used in critical situations with very heavy loads, where it is necessary to work with a material like steel, characterised by particular toughness. The strapping tool must therefore be able to apply very high tension to ensure a stable fastening, apply a seal or crimp to close the strap, and shear it at the desired point. These devices therefore have a particularly reinforced structure and ergonomic grips to make the operator’s work easier.
