As a specialized profile for shipbuilding, the DH36 bulb flat is a core component in modern shipbuilding that balances lightweight design with high strength. Tailor-made for the complex loading conditions of ship hull frameworks, it replaces traditional angle steel to effectively reduce structural deadweight.
The transition zone between the bulb and the web is manufactured using a precision controlled-rolling process. This design prevents hidden cracks caused by stress concentration—even under the repeated impact of ocean waves—thereby significantly extending the service life of hull longitudinals and bulkhead stiffeners.
As a supplier deeply experienced in marine-grade structural steel, BBN Steel offers a full range of DH36 bulb flats that strictly adhere to classification society standards. Every stage of production—from precise chemical composition adjustments to final ultrasonic flaw detection—undergoes rigorous quality control, ensuring compliance with construction standards for various oceangoing cargo vessels and engineering workboats.
We also offer custom-length services based on actual shipyard construction drawings. This eliminates the need for secondary cutting, helping clients shorten shipbuilding cycles and reduce overall costs associated with materials and processing.
Just like you, 70% customers choose long-term cooperation with BBN steel not only for our good product and service quality, good reputation in the international market, but also for our experienced one-stop raw material supply and further steel processing!
