  • Protective coated iron and steel products
    Patent number: 5066548
    Abstract: A protective coating of iron and steel products is described, wherein an adherent and rough layer of scale is formed, on which is directly deposited a layer of a protective material. The qualities of the layer of scale result from the fact that the product is shaped hot and the speed of its cooling is controlled so that the resultant thickness of scale is less than a threshold of adherence characteristic of the material and of the temperature at the end of shaping. The layer of protective material is obtained by metallization with zinc or an alloy based on zinc. The invention is principally applicable to long iron and steel products, and in particular to reinforcing bars for concrete.
