Flat-bulb steel

Flat-bulb steel are the most cost-effective, efficient and corrosion-resistant solution for plate stiffening requirements. Key advantages include an excellent strength to weight ratio delivering buckling resistance at a lower weight than with flat bars or angles.

The rounded edges of the flat-bulb steel profile mean there is no need for edge grinding prior to painting, saving time and money during fabrication. Paint degradation and the build up of corrosive debris is also reduced, extending life performance.
