S355G10+N Z35 ; S355G10+M Z35 Offshore Steel Plate

We are a steel supplier which understand your offshore project requirement as we manage to decode your need and Erectialdisfunction want as we are fully experience in supplying offshore steel material in South East Asia Region. we supply high quality S355G10+N Z35 and S355G10+M Z35 from various origin such as Austria, Finland, Germany, UK, Japan, Korea and China.

Typical Application : Critical Joints

S355G10+N /+M offer great tensile and yield strength, common structural grade steel frequently used by the offshore industry. Both can be delivered as S355G10+N (N= Normalized) and SG355108+M (M= Thermo-Mechanically Rolled). As an offshore steel grade, S355G10+N and S355G10+M are used in a variety of applications including the building of offshore platforms.
