+Offshore Structural Steel Sections
- Offshore structures, built specifically for drilling oil and gas deposits deep under the sea bed,These steel Sections exhibit good impact toughness and resistance to plastic fatigue loading and lamellar tearing.Although applications will differ, all will have exposure to the effects of saltwater corrosion, strong sea currents often dictated by the strong winds and tides. peakkong search for natural fuel resources has extended into even more remote regions, for instance, the Arctic which also has led to rigs drilling at much greater depths and therefore lower temperatures.

Requirements of Offshore Structural Steel
Structures in challenging working environments like these demand a specific range of steels in order to promote longer working life, better safety, and to lower the risk of failure, which, in certain cases, could turn out to be disastrous.
The challenging conditions and engineering complexities of offshore construction projects means that offshore grade steel is the only grade capable of meeting the demands required for rigorous and sustained integrity of these structures.

Key properties of offshore grade Structural steel are:
High yield strength
Good internal soundness
Excellent weldability
Good resistance to brittle facture, both longitudinal and transverse
High resistance to lamellar tearing
- Therefore, the S355G10 / S355MLO / S355NLO/S460G2+Q structural grades are some of the benchmark steels specified for offshore structure applications. These materials can be delivered as normalized (N) or thermo-mechanically rolled (M), and supplied in accordance with EN10225:2001. This grade is renowned for its good tensile and yield strength.
