Featuring Herm Sprengers attractive and robust surface, Matt Chrome. The production is similar to the standard steel chrome plated chains. Due to a small modification during the galvanisation procedures Sprenger reach this "matt" effect.
The matt surface is strong as you expect from the Sprenger chrome plated chains. The plating neither becomes shiny nor does it go off.

Whereas other manufacturers only dip the chains before galvanizing, Sprenger uses a different procedure of mirror-bright polishing. Dipping means to remove non-metallic unclean things like oil from the chains. The metal becomes clear but has no surface polishing.
The advantage of Sprengers polishing is that the surface becomes much smoother and has this special bright shine. After tumbling, the chains are nickel or chrome plated. The nickel and chrome baths are monitored permanently by a laboratory. Sprenger examines the grip of the nickel layer through 'bending' tests before the chains are chromium plated.
