Melted zinc-aluminum alloy coating "SG coating"

In the salt spray test, it has ten times the corrosion resistance of standard hot-dip galvanized coating.

SG plating is a molten zinc alloy plating system consisting of 5% aluminum and 1% magnesium. It is an alloy based on zinc, developed with technical support from Mitsui Mining & Smelting under the name "Super Galva," and has been enhanced with unique technology from Kowa Industrial for over 20 years. While zinc-based plating with about 5% aluminum has been commercialized in the steel sheet sector by blast furnace manufacturers and has established JIS standards, it is often technically challenging in the field of general molten zinc plating, and such plating is rarely performed. Furthermore, there are no other facilities boasting a production capacity of 3,000 tons per month with an 8-meter large kettle for alloy plating. SG plating has a proven track record in harsh environments prone to corrosion due to salt damage, such as coastal areas and heavy snowfall regions. Recently, in collaboration with Nippon Steel, SG plating has successfully developed high corrosion-resistant steel pipes. By combining Nippon Steel's "Strong Seam," known for its excellent workability, with SG plating, steel pipes with outstanding corrosion resistance and workability have been realized. **Features** - Exceptional corrosion resistance - Excellent as a base for painting - Powerful enough to handle large and bulk production - Environmentally friendly surface treatment For more details, please contact us or download the catalog.
