Three reference sections. One original drawing.
The 100, 75 and 57.5 mm sections belong to one magnesium alloy material, rather than separate material ranges. The drawing shows section heights of 100, 75 and 57.5 mm. The illustrated top widths are 27.38, 27.38 and 22.38 mm respectively, with theoretical developed widths of 300, 250 and 200 mm. Developed width is not finished height or wall thickness.
