Hot-rolled marine L-section steel, also known as unequal-side and unequal-thickness angle steel, is a new type of profile produced to meet the needs of large-scale ship construction. In addition to being used for large ships, L-section steel can also be used for marine engineering structures and construction engineering structures with higher requirements.
ASTM A131: Grade A, Grade B, Grade D, Grade E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40.
Our marine L-section steel for shipbuilding products have been certified by classification societies such as CCS, ABS, GL, LR, DNV, BV, KR, RINA, and RMRS.

1, The section coefficient and stiffness of marine L-section steel are larger than that of flat spherical steel.
2, When the section coefficient is the same, the thickness of the marine L-section steel panel is slightly thinner than that of the flat spherical steel, which is beneficial to improve the quality of the weld.
3, In the case of the same cross-sectional coefficient, increase the storage capacity of ships and improve economic benefits.
