Castellanza, February 12, 2025 - Tenova, a leading developer and provider of sustainable solutions for the green transition of the metals industry, has signed a contract with PT Tata Metal Lestari, one of Indonesia’s premium manufacturers of painted and coated steel products, and part of the global steel group Tatalogam, for the supply of a new hot dip galvanizing line for zinc aluminum magnesium alloy coated coils.
The new line, able to process Al-Zn, Al-Zn-Mg, and Zn-Al-Mg coated coils, will be installed on the premises of Tata Metal Lestari’s Sadang Plant in Cijaya, Kabupaten Purwakarta, Indonesia, with an annual capacity of 250,000 tons.
The scope of work includes the engineering, supply, and supervision of a complete set of equipment for the hot dip galvanizing line, including advanced level 2 electrical and automation systems, specifically developed by Tenova Italimpianti, a well-known Tenova brand and leader in technologies for reheating, heat treatment, strip processing, acid regeneration plants and cold rolling mills.
The new hot dip galvanizing line will produce first-class products with optimal surface quality and strip purity, thanks to the cleaning section, which removes surface contaminations, and to a combination of mechanical, hydrodynamic, and chemical processes. The furnace is designed to strictly separate the furnace atmosphere, the combustion process, and the ambient environment, preventing deterioration in the surface condition of the strip during heat treatment. The air knife systems also contribute to providing optimal quality for galvanized surfaces and the inline skin pass mill is designed to finish the coated surface with a controlled surface imprint, improving the strip shape.
“Thanks to this new project, PT Tata Metal Lestari will become a leading producer of aluminum, zinc and magnesium alloy coated steel coils for Indonesia and a reference point for the Western market,” stated Stephanus Koeswandi, CEO at PT Tata Metal Lestari. “We are pleased to collaborate with Tenova on this achievement, recognizing its expertise and capabilities in delivering customized and advanced technical solutions.”
“The concept design of PT Tata Metal Lestari’s line perfectly combines the highest technology for the production of Al-Zn, Al-Zn-Mg, and Zn-Al-Mg coated coils with up-to-date customized operational processes,” added Giuseppe Zanzi, Chief Representative Officer, South East Asia and Oceania at Tenova. “This new line can guarantee high quality and stable production, together with the flexibility to use three types of zinc, aluminum and magnesium alloys coatings.”
