In the salt spray test, it has ten times the corrosion resistance of conventional hot-dip galvanized coatings.
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 incorporated unique technologies from Kowa Industrial for over 20 years. While zinc-based alloys with approximately 5% aluminum have been commercialized in the steel sheet sector by blast furnace manufacturers, with JIS standards established, such plating is often technically challenging in the general molten zinc plating field, and this type of plating is rarely performed. Furthermore, there are no other facilities boasting a production capacity of 3,000 tons/month with an 8-meter large kettle for alloy plating. SG plating has a proven track record in harsh environments prone to corrosion from salt damage, such as coastal areas and heavy snowfall regions. Recently, in collaboration with Nippon Steel, we have successfully developed high corrosion-resistant steel pipes. By combining Nippon Steel's "Strong Seam," which has a proven track record as a well-processable steel pipe, with SG plating, we have achieved steel pipes that excel in corrosion resistance and processability. 【Features】 - Exceptional corrosion resistance - Excellent as a base for painting - Powerful enough to handle large-scale production - Environmentally friendly surface treatment For more details, please contact us or download the catalog.
