Chinese L-Section Steel

Chinese L-Section Steel

The Chinese L-section steel is a kind of special steel angles which is with unequal legs and different thickness of walls. It is also known as “unequal leg and thickness angles”. It is often used for shipbuilding. Compared with bulb flats, the Chinese L-section steel has larger section modulus and rigidity. What’s more, under the condition of same section modulus, the Chinese L-section steel can increase the loading and economic benefits. It is described by both leg length (longer first) and the both wall thickness (thinner first), eg. L250×90×10.5×15. In addition to shipbuilding, the Chinese L-section steel can be used for bridges, power transmission towers, beams... We are capable of supplying a wide range of steel grades and dimensions of the angles. The available steel grades including CCS A, CCS B, CCS D, CCS E, AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, Q235, Q345... Stainless steel L sections and galvanized L sections are also available. If you are interested in our products, welcome to contact us.
