This diameter band is common for landing gear legs, camera gimbals, mast sections and wing joiners, where a 1mm to 2mm wall holds stiffness without adding much mass.

For bulk, standard lengths are 500mm and 1000mm. Other lengths and bore combinations are quoted on request, and custom sizes start at 10 pcs, so resellers can run mixed 10- or 20-piece lots for OEM builds.
