Shipbuilding steel bulb flats are used in ships building and ocean engineering as plate stiffeners. There shape guarantees have many advantages compared with other reinforcement solutions, first, bulb flats are the most economical reinforcement for plates, second, they have obvious advantages in strength to weight ratio than other reinforcement.
High strength, well ductility, good corrosion resistance and excellent weldability;
A wide range of materials and dimensions;
High quality, produced by Chinese top steel mills with good reputation;
Long working time;
Widely used for shipbuilding, bridges, large buildings;
