Galvanised structural steel has the following mechanical properties - these are measured longitudinal to the rolling direction: 

	Rp min.3)	Rm min.2)	A80 min.1)
Grade	N/mm²	N/mm²	%
S220GD+Z	220	300	20

¹⁾ For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%.
²⁾ For all grades except S550GD+Z a range of 140 N/mm² can be expected for tensile strength.
³⁾ If the yield point is pronounced, the values apply to the upper yield point (R_eH).
