EN 10219 standard defines the S275NH square tube technical requirements for the delivery of round, square and rectangular cold formed welded hollow sections such as tolerances, dimensions and sectional properties.
EN 10219 S275NH cold formed hollow sections for steel construction ensure high mechanical resistance and high yield strength. S275NH welded structural hollow sections are used as a fixed load-bearing structures in the building and civil engineering, are suitable elements in mechanical engineering because of its static advantages, and are also used in aerospace and automotive industry. They are not suitable for dynamic loads.
EN 10219 cold formed square hollow sections S275NH are produced at room temperature, by cold forming the sheet which is longitudinally welded at the ends, and therefore also known as welded hollow sections. (At the request and the technical possibilities, the inner weld can be removed or smoothed, while the outer weld is already processed in most cases.) Due to the process of cold forming, there is a high level of residual stress remaining in the hollow sections which the can cause cracks during workload.
EN 10219 S275NH Cold Formed Hollow Sections Inspection and Testing
EN 10219 is subject to tensile testing in accordance with EN 10002-1, charpy impact test in accordance with EN 10045-1.
