Described is an assembly of at least two galvanized steel parts, the first part comprising a receiving limb having at least one opening and the second part comprising at least one head end which engages with the receiving limb and provided with at least one lip protruding in a first plane from the head end, the at least one lip passing through the opening and bending behind the receiving limb, whereby the bent end of the lip is substantially following a second plane intersecting the first plane and forming an angle, the lip engaging with and pressing the receiving limb against the head end, thereby connecting the two parts, whereby the intersection of the at least one lip with the plane bisecting the angle between the first and the second plane and cutting the bent lip, shows a curve relative to the intersection of the first and the second plane.
