INDATEN®355WP

Indaten355WP steel sheets are weather-resistant structural steels designed to provide excellent protection against atmospheric corrosion. Thanks to their specially developed chemical composition, Indaten355WP steel sheets naturally form a protective patina that slows down oxidation and significantly reduces the need for painting or additional surface treatments. This makes them an excellent solution for steel structures exposed to outdoor environments where durability and low maintenance are essential.

Sidastico supplies cut-to-size Indaten355WP steel sheets in a wide range of thicknesses and dimensions. Precision cutting ensures excellent dimensional accuracy, minimizes material waste and simplifies subsequent fabrication processes. Every order is supplied with an EN 10204 3.1 certificate, guaranteeing full material traceability and compliance with European quality standards.

The material combines high mechanical strength, excellent weldability and very good processing properties. It is suitable for laser cutting, plasma cutting, bending and other common fabrication processes. Furthermore, the naturally formed protective patina provides long-term corrosion resistance, extending the service life of steel structures while reducing maintenance requirements.

Typical applications include bridges, architectural façades, railway infrastructure, industrial facilities, steel structures and outdoor construction projects. It is particularly suitable wherever long service life, weather resistance and reduced maintenance costs are key design requirements.

With extensive stock availability and advanced processing capabilities, Sidastico supplies cut-to-size Indaten355WP steel sheets with fast delivery times, consistent quality and reliable technical support for demanding industrial applications.

Brief Description

High-strength weathering structural steel designed to provide excellent resistance to atmospheric corrosion. Thanks to alloying elements such as copper, chromium and phosphorus, it naturally develops a protective surface layer that reduces the corrosion rate and increases the service life of the component.

Applications

Architectural facades, outdoor structures, bridges, metal constructions, containers, chimneys, urban furniture, infrastructure projects and applications exposed to atmospheric conditions.
