Chromium Coated Steel Sheet
Chromium-coated steel sheet, also referred to as Wuxi steel, is a type of cold-rolled low-carbon steel sheet or strip that is plated with metal chromium and chromium oxide on both sides. This material was developed as a more cost-effective substitute for tinplate, primarily for use in can and cap production. The coil form is called chromium-coated steel strip, while the cut sheets are known as chromium-coated steel plates. GNEE Steel is a leading manufacturer of premium chromium-coated steel, tinplate, and a range of cold-rolled coils and sheets, including galvanized steel products. We ensure that all our products meet international quality standards and can be customized to suit your specific requirements. Don't hesitate to get in touch with us!
Chromium Coated Steel Sheet features
Excellent Paint Adhesion: The coating has superior adhesion compared to tinplate, making it suitable for the production of DRD (drawn and redrawn) cans and glued cans.
Excellent Resistance to Thermal Denaturation: Resistant to high-temperature baking, maintaining color stability and preventing any deterioration in material performance.
Excellent Anti-Sulfurization: The metallic chromium layer offers excellent resistance to sulfurization, making it ideal for packaging protein-rich foods such as fish.
Outstanding Resistance to Filiform Corrosion: The material exhibits excellent resistance to filiform corrosion under the paint film.
Superior Alkali Resistance: The chrome-plated layer is non-amphoteric, providing greater suitability for packaging alkaline products such as detergents and pigment dispersants.
