CJSC “ZETO” uses new high-efficiency environmentally safe hot dip galvanizing line for metal structures based on the “Hasco” equipment and technology of the federal state unitary enterprise “Central research institute of iron industry named after I.P. Bardin”. A horizontal bathtub with 6,5x1,2x3 m sizes allows galvanizing a full range of metal structures. The practice of hot dip galvanizing at CJSC “ZETO” covers more than 40 years and presently coating quality conforms to the most severe anticorrosion protection requirements. Hot-dip galvanizing is the best method of steelwork protection against corrosion among all known methods.
