Sawed cross sections deburred blank, i.e. not surface treated.
Construction tubes GN 990 can be supplied in these standard lengths.
The tolerances specified for the outside diameter of the round construction tubes comply with the requirements for split mono-block connector clamps. Two-piece connector clamps allow obviously larger tolerances on construction tubes.
