How to Read the Tables
Cast section is the billet size at the mould exit, e.g. 130 × 130 mm. Radius R is the casting machine radius (R6 = R6000 mm); the tube must match it exactly. Length L is the overall tube length; 812 mm (32 in) and 900 mm are the common standards.
Send the marking on your old tube (for example "150×150×900 R6000") or your caster drawing and we confirm taper, wall thickness and plating before quoting.
