Our company is certified with ISO 9001:2015 Quality Management System, ISO 14001:2015 Environmental Management System and ISO 45001:2018 Occupational Health & Safety Management System, ensuring standardized management in production, environment protection and workplace safety.

Our concrete batching plants and related equipment have passed the CE conformity assessment in accordance with the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU, covering HZS series batching plants, WCB series stabilized soil mixing plants, PLD series aggregate batchers and JS series concrete mixers.

We also own multiple national utility model patents on key batching plant technologies, including mobile concrete batching plants, detachable container-type batching plants, powder conveying and cleaning devices, and aggregate batching bins. These patented designs reflect our continuous investment in technology research and development.

Every machine goes through strict quality control from raw material inspection, welding and assembly process control, to full-load test running and final inspection before delivery. Our professional test lab and experienced engineers ensure stable performance, long service life and safe operation of all equipment.
