The technical delivery conditions for hot finished steel structural hollow sections made from high strength and weather resistant steels are specified in standards like EN 10210-3:2020. This European standard outlines the requirements for hot finished structural hollow sections of non-alloy and fine grain steels that possess enhanced mechanical properties, including high strength and resistance to atmospheric corrosion. Here’s an overview of the key aspects covered by EN 10210-3:2020:

– The standard applies to hot finished structural hollow sections of circular, square, rectangular, or elliptical shapes.

– It includes steels with enhanced properties such as high strength and resistance to atmospheric corrosion (weather resistant steels).

– Specifies grades of steels suitable for hot finished hollow sections, including those with higher yield strengths and improved weather resistance,S500WH.S700WH.

– Ensures compliance with mechanical properties such as yield strength, tensile strength, and impact toughness.

– Defines requirements for dimensions, tolerances, lengths, and permissible deviations for structural hollow sections.

– Ensures uniformity in size and shape to facilitate construction and assembly.

– Specifies testing methods and requirements to verify compliance with mechanical properties, including impact testing at specified temperatures.

– Ensures consistent quality and reliability of structural hollow sections for various applications.

– Suitable for use in construction, infrastructure, and engineering projects where high strength and weather resistance are critical.

– Used in applications such as bridges, buildings, offshore platforms and other structures exposed to harsh environmental conditions.

– EN 10210-3:2020 ensures compliance with European standards and promotes safety, quality and performance in structural applications.

– Provides a framework for manufacturers to produce and supply high-strength, weather-resistant structural hollow profiles that meet industry standards.
