QBF rubber Sidewall Conveyor Belts have become a vital force behind several rail transit projects in Shenzhen, delivering exceptional anti-stick and high-efficiency muck discharge performance that sets a new standard for shield tunnel construction.

As the leading supplier of sidewall conveyor belts for Shenzhen Metro, QBF rubber commands approximately 60% of the market—a testament to our reliability and technological edge. In response to Shenzhen’s challenging geological conditions, including high clay content, elevated moisture levels, and difficult material discharge, our R&D team went to the front lines. Through on-site soil sampling and customized formulation development, we introduced a next-generation sidewall belt with superior anti-stick and self-discharging properties. The results speak for themselves: the belt significantly reduces material carryback and cleaning downtime, boosting sticky muck removal efficiency by 50% to 80% compared to traditional large-angle rubber belts.

On landmark projects such as the Dapeng Branch Line of the Shenzhen-Huizhou Intercity Railway and the Qianhuang section of the Suishen Intercity Railway, QBF rubber delivered large-format vertical lifting sidewall belts capable of reaching heights of up to 75 meters. These belts tackled the toughest challenges—massive conveying volumes, extreme lift heights, and installation in space-constrained environments—with ease. Backed by our end-to-end service model, from product selection and manufacturing to installation and commissioning, we ensure every project stays on schedule and on point.

Right now, our professional installation teams are on-site for sidewall belt replacement services across Shenzhen Metro, executing rapid changeovers that save valuable time and keep operations running smoothly. While QBF rubber is proud to be a trusted partner to Shenzhen Metro, our footprint extends far beyond—with successful deployments in major global markets, including the Moscow Metro, Japanese Metro, German Metro, and Indian Metro.
