Steel Coil - Building & Construction Material always reliable with Topest Manufacturers and Suppliers - China North New Material

  • Prepainted Steel Coils

    With GI (aluzinc) as base metal, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance. 

  • Specification:

  • Application:
    Outdoor:
    roof, roof structure, surface sheet of balcony, frame of window, door, door of garage, roller shutter door, booth, Persian blinds, cabana, etc.

    In door:
    door, isolater, frame of door, light steel structure of house, home electronic appliances, etc.


  • Hot-dip Galvanized Steel Coils  

    are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications.
