S355N Structural steel,EN10113-2 S355N steel plate supplier
S355N steel is a structural steel grade. S means structural steel, 355 means min yield strength for thickness less 16mm expressed in Mpa, N mean the delivery condition. S355N Structural steel is used in many applications, combining good welding properties with guaranteed strengths.
S355N steel is used above all for manufacturing highly stressed welded structures in the construction of heavy machinery, bridges and steel structures.
