Galvanized SteelDescriptionHwafone hot-dip galvanized and galvanized coils have superior performance and smooth surface. They have good corrosion resistance, molding and coating properties, and are mainly used in construction, automotive, metallurgy and electrical appliances. In the construction industry, it is mainly used to make roofs, prefabricated keels, pre-casting partitions, various doors and windows, etc.; the automotive industry is mainly used for body shells, chassis, doors, fuel tanks, etc.; the metallurgical industry is mainly used for color coated board substrates and steel windows. Blanks, etc.; the electrical industry is mainly used for the outer casing of electrical appliances.Applications
Details
Resistance to acid rain
Coating protection mechanism: It is very easy to form acid rain in the high level of industrial emissions or pollutants environment. Acidic penetration is formed in the surface of pre-painted steel, and accelerates the corrosion, forming blistering, peeling and so on.
Resistance to ultraviolet rays
Coating protecting Mechanism: Pre-painted steel in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and loss of gloss, lose paint quickly.
Resistance to humid heat
Coating protecting mechanism: In hot and humid environments, high osmotic pressure of water vapor accelerates penetration, forming the degeneration of painting film, then the corrosion of the substrate, with the phenomenon of bubbles and peeling.
Resistance to low temperature
Coating protecting mechanisms: Most of the paint can keep stable processing performance above -10 degree, but at alpine region, the temperature will be below 20-40 degree, normal paint will become brittle, bend cracking, or even lose paint, thus protection function is lost totally.
Dual strong
Intense heat reflectance: Hwafone pre-paint steel uses aluminum zinc substrate, the reflectivity is two times stronger than galvanized sheet, therefore they are the ideal energysaving materials.
Intense skin-pass surface: After skin-pass process, Hwafone galvanized steel substrate overcomes the common tension leveling lines and the surface is flat and smooth.
