It has been of great challenge for HAC sidewall belting when heavy duty applications.

To extend the sidewall belting life and to minimize the force of the bend pulley on the steel cord, QBF has innovated by "MAGIC" technical designation to prevent the steel cord from being pulled out or broken due to excessive force, thus achieve the effect of prolonging the service life. The "MAGIC" sidewall belting has contributed to heavy duty safe and long-life time performance.
