Steel bulb flat,which is one kind of mid structural steel, applying in shipbuilding industry and bridging industry.

Steel bulb flat is one kind of mid structural steel, applying in shipbuilding and bridging industry. In recent years, as rapid development of shipbuilding, there is a large-quantity market demand in bulb plate. It is the important material for vessel’s keel corresponding to steel plate for main body.

Executive standard: GB/T9945-2001, EN10067:1996, JIS G3192,ISO 657-19.

Grade: ordinary strength (A, B and D); high strength (AH32, AH36, DH32, and DH36). Different plates authenticated by different classification societies shall correspondingly choose bulb plates.

Approved by CCS GL DNV LR NK KR RINA ABS (ASTM A131) and BV Authentication Classification society.
