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 use of bulb flat plate stiffeners in ship design is said to reduce building time and maintenance cost. Companies that produce bulb flat plate stiffeners manufacture each stiffener as a single unit, which reportedly results in less production cost compared to welded or fabricated stiffeners.
