Hi - i know there are tables in the TG20 mentioning the SWL of tubes with their allowable struts /length. but these are type 4 tube. does anyone know where i can specifications for 3.2MM tube and also black steel tube "meaning tube that is not galvanized - or is it safe to say that this tube has the same capacities as the galvanized tube.
thanks
thanks
