Thanks to the balance between mechanical strength, weldability and ductility, Marcegaglia Plates structural steels deliver high and consistent performance over time.
Available according to EN 10025-2, EN 10025-3 and EN 10025-5 standards, Marcegaglia Plates structural steels include non-alloy and fine-grain steels with enhanced resistance to atmospheric corrosion, ideal for exposed environments and variable climate conditions.
Our heavy plates are available in a wide range of grades, from S235 to S460, in the main delivery conditions (+AR, +N, NL, W), meeting different mechanical and performance requirements.
Availability according to the main ASTM standards – including A36, A283, A572, A573, A588 and A709 – allows us to cover even complex infrastructure applications, including bridge structures, where reliability, durability and fatigue resistance are essential.
Steel as a bridge between engineering and vision
Marcegaglia’s experience in manufacturing structural steels translates into materials capable of combining performance and design, becoming an integral part of major works of contemporary engineering.
Every project made with our heavy plates is created to endure over time and support the future, backed by internationally recognized quality.
