PRODUCT 02.03 · OVAL TUBE
Oval tube 40×80 mm — the arch of a 9.6 m bay where the load case is real.
40×80 mm oval, wall 1.5–2.5 mm, straight or bent to your arch radius. Where a 9.6 m house stops looking light.
An 40×80 oval is specified by the outside dimensions and the wall. The 40 mm face is what the clamp grips; the 80 mm depth is what resists bending in the plane of the arch. When a buyer changes from a smaller oval to this one but keeps the same clamps, they are usually trading a little clamp clearance for noticeably more depth — check the clamp bore before you commit.
