Carbon steel from a tandem mill is processed. Thermal processing is used in order to achieve uniform metallurgical structure and strength with subsequent zinc or zinc alloy coating, followed by skin passing, tension-leveling, and passivation. 

Continuous galvanizing lines (CGL) from JJRS are high-quality solutions for the annealing and galvanizing process. These lines are available for a wide range of products, such as CQ,DQ,EDDQ,BH,AHSS, and MP.

This product flexibility is the result of advanced technology, for example the highly sophisticated direct-fired furnace and the differential rapid jet cooling section. 

Hot dip aluminum zinc silicon steel plate -Galvalume(Referred to GL steel plate), is steel plate to hot-dip coat aluminum (Al 55%),zinc (Zn 43.5%), silicon (Si 1.5%) alloy on the surface of the steel plate. Itis a steel matrix composite, has excellent corrosion resistance. Hot aluminumzinc alloy steel plate performs outstanding in atmospheric corrosion resistance,thermal oxidation resistance of the aluminized steel plate and electrochemicalprotection of the galvanized steel plate.

We provide two kinds of technologiesof hot dip galvanizing (galvalume) lines: "United States Steel Corp"and independently researched and developed “JJRS-Sendzimir” .
