It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service. The class of the cross-section in bending and/or compression depends on the ratio of its diameter D to the wall thickness t, adjusted by the factor that takes into account the value of the steel yield stress fy: The diameter to wall thickness limits D / t for cross-section classification according to EN1993-1-1 Table 5.2 are presented below: For the case of circular hollow sections (tubular sections) that cannot be classified as Class 3 their strength and stability verifications should be based on EN 1993-1-6: Strength and Stability of Shell Structures.
