Due to the insufficient natural corrosion resistance of Q235 cold rolled carbon steel plate, it is necessary to enhance protection through surface treatment or structural design in practical applications.
The surface coating protection of Q235 cold rolled carbon steel platee can be coated with anti rust paint, sprayed with epoxy zinc rich primer, polyurethane topcoat, etc., to isolate metal from contact with corrosive media, such as steel structure bridges and automotive chassis,hot dip galvanizing or electroplating can also be used to form a zinc protective layer through hot-dip galvanizing or electroplating processes, utilizing the sacrificial anode properties of zinc to protect steel substrates, such as angle steel and channel steel used in construction.
Perform environmental isolation and maintenance to avoid long-term exposure to humid or corrosive environments. Regularly clean surface stains, such as Q235 parts in industrial equipment that require regular rust removal,
for important structures such as bridges and pressure vessels, cathodic protection methods such as sacrificial anodes can be used to further delay the corrosion of Q235 cold rolled carbon steel plate.
