JSW Steel Orders ANDRITZ Galvanizing Line for Automotive Steels

JSW Steel Ltd., one of India’s largest integrated steel manufacturers, has selected international technology group ANDRITZ to supply a continuous galvanizing line for its steel plant in Toranagallu, Karnataka, India. The new processing line is designed to produce high-grade galvanized steel, specifically Advanced High-Strength Steel (AHSS), to serve the growing automotive manufacturing sector. Burgel Guido, Senior Vice President of ANDRITZ Metals Processing, stated that the strategic project reflects the company's ability to deliver high-performance solutions for advanced materials and reinforces the long-standing partnership between both organizations.

With an annual production capacity of approximately 500,000 tons, the line will process steel strip up to 1,900 mm wide and 2.60 mm thick, capable of producing AHSS grades with tensile strengths up to 1,480 MPa at line speeds of up to 180 m/min. ANDRITZ's comprehensive delivery scope covers the engineering, manufacturing, and supply of the entire line, including terminal equipment, a chemical cleaning section, an advanced annealing furnace, a zinc coating pot with after-pot cooling, a skin pass mill, a tension leveling line, and post-treatment sections. Start-up is scheduled for 2028.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

The automotive industry's push toward vehicle lightweighting—driven by stringent fuel economy norms and the need to offset heavy battery packs in electric vehicles (EVs)—has accelerated demand for third-generation Advanced High-Strength Steels (such as Dual-Phase, Complex-Phase, and Martensitic grades). Producing AHSS with tensile strengths up to 1,480 MPa while applying a uniform zinc corrosion barrier requires precise thermal control in continuous galvanizing lines. The furnace must achieve rapid heating and ultra-fast cooling cycles to lock in specialized metallurgical microstructures without compromising zinc adhesion or surface smoothness. Furthermore, as India continues to expand its domestic automotive manufacturing ecosystem, investments in local AHSS galvanizing lines reduce reliance on high-grade imported steel and ensure reliable supply chains for vehicle safety structures and body-in-white (BIW) panels.
