ArcelorMittal has expanded its flat steel product range, while at the same time DIN 55634 for steel flat products was revised. The standard regulates geometric tolerances, surface quality, and mechanical properties of hot-rolled flat steels used in structural engineering according to Eurocode 3. Whether the standard update was initiated by the Luxembourg steel company's product development remains unclear – such parallelism is common in manufacturer-driven innovations with broad market relevance. Planners should take the revised standard requirements into account when selecting materials for beams, columns, and connecting elements, particularly when extended strength classes or tighter tolerances are required.
