Ship Building Steel section

Bulb bars/flats are asymmetrical plate stiffeners used for ship building hull construction (Ship Hull, Ballast Tanks, and Cargo Holds) & Bridges (Box & Plate Girder, Steel Decks, and Expansion Joints). These special profiles provide a wide range of benefits compared to conventional plate stiffeners used for the purpose. The benefits are available at the time of construction as well as during products (Ship / Bridge) life. The significant benefits prompted the designers/constructors to use these special profiles on increasing scales.
