Zink GT: the door to banish corrosion
The purity of galvanised steel. Those who value the aesthetic simplicity of Zink GT will also be pleased with its astonishing durability. To produce the entry level model in the Steel range, Ballan adopted technology derived from the aeronautics industry that involves joining steel sheet components by means of hardened joints driven at very high speed.
This technique, know as cold welding, increases corrosion resistance because none of the zinc coating is removed at the site of the joint.
