Why You Should Consider Anti-corrosion in Your Steel Structural Project?

The hot-dip galvanized is one of the most important anti-corrosion methods for steel structures. Especially in outdoor and moist environments, hot-dip galvanizing protects steel structures from environmental erosion by immersing them in a molten zinc solution, which forms a dense galvanized layer on the surface.

By spraying special anti-corrosion materials on the surface of the steel structure, a protective film is formed thus preventing the steel structure parts from reacting with the external environment. It should be noted that a series of treatments such as sandblasting and rust removal are required before painting to facilitate better adhesion of the paint to the steel structure surface.

Cathodic protection is an electrochemical corrosion prevention method that prevents corrosion from occurring by applying a cathodic current to a steel structure to make its potential lower than that of the metal in the surrounding environment. Cathodic protection is commonly used for steel structures underwater or in the soil, such as submarine pipelines and dock piles.

Weathering steel contains metal elements such as phosphorus, copper, nickel, and chromium, which can form a protective layer on the surface of the steel, thus improving corrosion resistance. Common weathering steels are Corten steel plates, S355JOW steel plates, ASTM A588 steel plates, SPA-H steel plates, etc.
