It corresponds to the relevant shear area A v multiplied by the steel yield stress in pure shear f y / √3 corresponding to the yield criterion in EN1993-1-1 §6.

Bulb flats can be applied in almost all shipbuilding vessels, such as offshore, cruising, yacht, ferries, barges, fishing, repairing and etcetera. From railheads and bars to bushes, collars, and scrolls, we have everything you need to create beautiful gates, railings, balustrades, and more. for buildings, or the relevant parts of EN1993 for other type of structures, and the National Annex.

The basic geometric properties of the cross-section are calculated by using the fundamental relations of mechanics. Class 3: Elastic bending moment resistance develops but local buckling prevents the development of plastic resistance.

The classification of the circular hollow sections (tubular sections) is specified in EN1993-1-1 Table 5. Nowadays Bulb flats are the most used structure profiles for the Shipbuilding construction to reinforce steel plate. Therefore the presented cross-section resistances are indicative values applicable for special cases.The geometric properties that fully define the cross-section are: external diameter D and wall thickness t.

The diameter to wall thickness limits D / t for cross-section classification according to EN1993-1-1 Table 5. Flat steel bars are used in a wide variety of applications, including the manufacture and repair of gates, railings and fencing, and for decorative purposes. Baglietto SRL have started providing bulb flats since 70s, remarking the significant request, initially from the ship-repairing field, so then specializing more and more in the shipbuilding sector also.Class 1: Plastic bending moment resistance develops and plastic hinge develops with rotation capacity adequate for plastic analysis. and the National Annex for the case of steel buildings, or the relevant parts of EN1993 for other types of structures.

The plastic section modulus W pl corresponds to the maximum plastic bending moment when the axial force of the cross-section is zero and the stress profile is fully plastic.Due to symmetry the centroid of the cross-section (center of mass) as well as the shear center are located at the center.
