galvanized steel angle

Galvanized angle steel refers to a layer of metal zinc coated on the surface of ordinary angle steel, the purpose is to prevent the surface of the angle steel from corrosion and extend its service life. Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is to immerse the rust-free angle steel in a zinc solution melted at about 500℃, so that a zinc layer adheres to the surface of the angle steel, thereby achieving the purpose of corrosion protection. Cold-dip galvanized angle steel uses the principle of electrochemistry to ensure full contact between zinc powder and steel, generating an electrode potential difference for corrosion protection.
