EN 10210-3 Structural Hollow Sections mainly cover high-strength and weather-resistant steels for structural purposes. High-strength steel has proven successful in heavy equipment and vehicles, offering lighter weight, wear and impact resistance, and easy fabrication. These same benefits extend to structural engineering applications: longer spans, reduced weight for lower foundation loads, and greater load-carrying capacity are all achievable thanks to high-strength steel.
