EN 10210 is a European standard that specifies the requirements for hot-finished structural hollow sections made of non-alloy and fine-grain steels. It covers the dimensions, tolerances, and mechanical properties of these sections, ensuring they are suitable for use in construction and engineering applications. The standard aims to provide a consistent framework for manufacturers and users, promoting safety and reliability in structural design. By adhering to EN 10210, engineers and architects can ensure that the materials used in their projects meet established quality and performance criteria.
