1 Architectural solution for corrosion resistant alloy steel.

2 Super Corrosion resistant Alloy steel Architectural Solution for Corrosion Resistant Alloy Steel. SUPERMAG is an architectural product made of high corrosion resistant alloy steel (5times better than hotdip zinc 5% alloy coated steel and 10 times than hotdip zinc coated steel) coated with a hybrid ceramic surface and guarantees minimum yield strength of 32ksi with good ductility. Typical uses are superior architectural product for rollformed roofing sheets, sidings and suitable interior applications.

3 What is SUPERMAGS? Precoated steel combined with DSP s unique coating technology offers the ultimate architectural solution for traditional roofing, cladding and finishing materials. Product Configuration Product Characteristics Ceramic Coating Corrosion resistant: Scratch resistant: SUPERMAGS is 10 to 20times tougher than Galvanized steel with selfhealing property. SUPERMAGS offers better scratch resistance than Galvanized steel. SUPERMAGS Architectural solution for corrosion resistant alloy steel. 01 Specification Typical Thickness (mm) 0.4 / 0.5 / 0.6 Typical Width (mm) 620 / 1000 / 1219 * Maximum and minimum thicknesses outside the typical range stated above may be supplied on an inquiry basis only. Mechanical Properties Corrosion Resistant Alloy Steel Graceful color: No discoloration with elegant colors achieved by DSP s special ceramic coating. Environment friendly: Cr free with minimum molding pollution for green environment. Replacement for GI: Cost effective: Perfect replacement for post hot dip Galvanized products. long lasting service life saves maintenance and installation cost.

4 Corrosion Resistance Mechanism for the cut ends' self healing alloy coated layer The thin zincbased film containing MG flows over the cut end Red Rust Initial exposure period Long exposure period Expansion of cut ends SUPERMAGS Architectural solution for corrosion resistant alloy steel. MG in the coating layer catalyzes to form a fine and stable corrosion product, called Simonkolleite, Zn5(OH)8CI2.H2O and this product is adhered tightly on the surface like a protective film which prevents corrosion. Moreover, when the red rust caused on the cut end parts, the parts are also covered by the product for preventing corrosion.

6 What is NCC Coating? Nano Ceramic Coating Through a special electorchemical coating process, a hybrid coating of organicinorganic later is creatd on the surface that enhances antibacterial, antipollution and antifingerprint properties for minimal maintenance and cleaning. NCC even makes surface stronger against rust than the normal while creating aesthetically pleasing and elegant colors. SUPERMAGS Architectural solution for corrosion resistant alloy steel.

7 What is NCC EX Coating? Nano Ceramic Coating EX Superhydrophilicity PVD Coating SUPERMAGS Architectural solution for corrosion resistant alloy steel. 05 Anti Pollution Organic Matter Decomposition Fingerprint Decomposition A hybrid coating that forms a hybrid organic inorganic layer on the surface of the coated material through an electro chemical coating process. The coating is always EX clean because of the selfcleaning ability and organic matter decomposition effect.
