Thanks to THALE clamps it is much easier to select all the structural elements for mounting of the rainwater system so that they form a single coherent aesthetic entity. ANTIQ clamps are dedicated for installation in historical buildings and rooms where pipes run along the wall surface (lofts in historical factories). The surface of the clamp is coated with a layer of black zinc lamellar coating, which is finished with a matte powder coating. This method of corrosion protection gives a salt spray resistance of more than 1500 hours when tested according to ISO 10289.
