AND EMBEDDED FITTINGS
Steel embedded fittings and joining element of ferroconcrete structures should be generally protected from corrosion. The main method of their protection is galvanization and VMP HOLDING recommends one of its types - the "cold galvanization" with using zinc-rich primers ZINOL
. The technology consists of application of zinc-rich coatings on steel. It gives possibility to use the unique protective properties of zinc dust in case of absence of production facilities for traditional hot dip galvanization. In addition, the examinations confirm that in severe environments in existing of chloride and sulphate the zinc rich primer durability is higher than hot dip galvanizing coating durability. The zinc-rich primers can be applied in the shop and in the field.
