B550CL steel Processing
Wheel is made up of the rim and the disk. The main processing technique for rim is roll forming. Punch forming and spin forming are usually applied for disc. Punch forming is mainly used for disc of passenger cars, while disc of commercial cars are usually punch-formed (wigh inner tire) or spin-formed (without inner tire).
