Hainan Steel tells you: a large steel commonly used protection methods

         Zinc, aluminum and steel are negative potential sacrificial anode is formed so that the protective effect of basic iron and steel have been protected. Sprayed aluminum coatings currently used to prevent industrial atmosphere, marine atmosphere corrosion, Hainan steel which is characterized as follows:
(1) sprayed aluminum coating and steel substrate binding solid, long coating life, long-term economic good;
(2) technology and flexible, suitable for large-scale and long-term protection is important hard steel structure maintenance, field construction; Hainan Steel
(3) zinc spray or sprayed aluminum coating plus anti-corrosion coatings closed, can greatly extend the life of the coating, from the effects of the theoretical and practical point of view, spray zinc or aluminum spray coating is the best low-level anti-corrosion coatings. Metal coating layer and anti-corrosion coating composite coating protective coating life much longer than the metal coating layer and anti-corrosion coatings and protective layers of both life as a single protective layer coating life several times.
Heavy-duty long-lasting coating consists of primer, paint and topcoat center.
From the long-term economic thinking, sprayed aluminum coating the most economical, but a one-time investment, good construction coating may be 10 years without maintenance. Epoxy zinc-rich primer + epoxy micaceous iron center polyurethane acrylic paint and lasting protection system with better economy
Steel commonly sprayed zinc or aluminum spray, increased corrosion coatings constitute long-term preservation structure, or by supporting the heavy-duty paint coating protection. Zinc, aluminum has great resistance to atmospheric corrosion properties. Spray sprayed zinc or aluminum on steel structures.
