Galvanized DX51D+Z275 steel sheets are hot-dip galvanized steels manufactured in accordance with EN 10346. They are designed for applications requiring excellent corrosion resistance, outstanding formability and long-term durability. The Z275 coating, with a nominal zinc mass of 275 g/m² distributed over both surfaces, provides effective protection against moisture, weather exposure and corrosive environments. As a result, galvanized DX51D+Z275 steel sheets are widely used in industrial manufacturing, construction projects and metal fabrication where reliability and service life are essential.
Sidastico supplies cut-to-size galvanized DX51D+Z275 steel sheets in a wide range of thicknesses and dimensions. Precision cutting ensures excellent dimensional accuracy while reducing material waste and improving production efficiency. Every order is supplied with an EN 10204 3.1 certificate, guaranteeing full material traceability and compliance with European quality standards.
This hot-dip galvanized steel offers excellent processing characteristics. It is suitable for laser cutting, punching, bending, roll forming and conventional sheet metal fabrication. Furthermore, the zinc coating provides durable corrosion protection throughout the product’s service life. It also helps reduce maintenance costs and improves the long-term performance of finished components, even when exposed to demanding environmental conditions.
Typical applications include roofing systems, wall cladding, façade panels, structural profiles, ventilation ducts, cable trays, electrical cabinets, shelving systems, agricultural equipment, automotive components and household appliances. The material is also widely selected for industrial enclosures, storage systems and lightweight steel structures. Thanks to its high-quality surface finish, it is ideal for painting, powder coating and additional finishing processes that require a clean and uniform appearance.
With extensive stock availability and advanced processing facilities, Sidastico supplies cut-to-size galvanized steel sheets with fast delivery times, consistent quality and reliable technical support. Customers benefit from flexible production, customized dimensions and a material that combines corrosion protection, excellent workability and dependable performance for a wide range of industrial applications.
