Bulb Flat Shipbuilding Product Description
Ball flat steel is a type of special steel, which is composed of a flat web and a spherical ball head. It is an asymmetric steel. The material of spherical flat steel corresponds to the ship plate, which is divided into general strength (A grade, B grade and D grade, etc.) and high strength (AH32, AH36, DH32 and DH36, etc.). Ship plates certified by different classification societies need to be matched. Use flat bulb steel approved by different classification societies.
Common uses of bulb flat steel:
Shipbuilding: They are used to make hulls, decks and superstructures. Its unique shape provides excellent load-carrying capacity and helps transfer forces efficiently, thereby increasing the overall structural integrity of the vessel.
Reinforcement and Reinforcement: They can be welded or bolted to plates and profiles to increase strength and stiffness, especially in areas where stress is concentrated or additional support is required.
Offshore structures: They help improve the overall strength, stability and load-bearing capacity of these structures, which often operate in harsh and challenging marine environments.
Due to its special shape and structural characteristics, spherical metal flat steel has the advantages of improved strength-to-weight ratio, high material usage efficiency, easy manufacturing and installation, etc.
