Terneplate Steel Sheet for Roofing
Flat-rolled nonalloy steel sheet over 600 mm wide, coated with a lead-tin alloy known as terne metal, commonly used for durable roofing and siding applications. This product falls under HTS 7210.20.00.00 because it is plated or coated with lead (terne-plate) and meets the width requirement for flat-rolled iron or nonalloy steel products. The lead coating provides corrosion resistance essential for outdoor exposure.
Lead-Coated Steel for Battery Casings
Wide flat-rolled nonalloy steel sheets plated with lead, exceeding 600 mm in width, designed for manufacturing protective battery containers. Classified under HTS 7210.20.00.00 due to the lead plating on nonalloy steel base meeting width criteria, with the coating preventing acid corrosion. This terne-like coating ensures longevity in electrochemical applications.
