What is a Aluminum Bulb Flat ?
Aluminum bulb flat is a specialized structural profile widely used in shipbuilding, marine, and offshore industries due to its lightweight, corrosion resistance, and high strength-to-weight ratio. Its unique shape—a flat base with a rounded bulb—provides excellent structural support while reducing weight, making it ideal for hull stiffeners, ship frames, and offshore platforms.
The advantages of Aluminum Bulb Flat Extrusions over other types of extrusions are significant. Compared to traditional extrusions such as angles or flats, bulb flats offer better performance in load distribution and structural reinforcement. The bulbous profile helps distribute loads more evenly and enhances the overall rigidity of the structure in which they are used.
Key Features of Aluminum Bulb Flat:
Lightweight & High Strength: Reduces overall weight while maintaining structural integrity.
Corrosion Resistance: Excellent performance in marine and offshore environments.
Easy to Weld & Fabricate: Suitable for customized shipbuilding applications.
Cost-Effective & Durable: Requires minimal maintenance, offering long-term durability.
Applications of Aluminum Bulb Flat:
Shipbuilding & Marine Structures – Used in hull reinforcement and deck support.
Offshore Platforms & Oil Rigs – Ensures durability in harsh marine conditions.
Bridge Construction – Provides stiffness and stability with reduced weight.
Industrial & Structural Fabrication – Suitable for lightweight structural framewo
rks.

Processing and Manufacturing of Aluminum Bulb Flat Extrusions
- Extrusion: Profiles are typically manufactured through an extrusion process, where aluminum billets are forced through a die to form the desired cross-sectional shape. This process allows precise control over the dimensions and consistency of the profiles.
- Surface Treatment: To further enhance corrosion resistance and appearance, profiles can undergo various surface treatments, such as anodizing or powder coating.
