Chromoly Tube for Kart Frames
Racing kart frames demand tight-tolerance tube that bends cleanly and welds without losing strength. We supply precision chromoly tube in the 25CrMo4 (1.7218) / AISI 4130 class, normalized condition.
Sizes for Chassis Fabrication
Common chassis diameters of 25, 28, 30 and 32mm with wall 1.5-2.0mm are available - 28mm and 32mm being the typical CIK-style chassis range. Tubes are straightened and can be cut to length.
Custom Engineering Welcome
Non-standard dimensions, special grades and tighter tolerance requests are handled by our in-house engineering team before production - tell us the frame drawing and target weight.
