The Group upholds its “Quality comes first” principle. All the cement companies under the Group have passed the ISO9001 quality management system attestation, and have independent quality management teams to enforce strict and effective quality management measures on the composition of raw ingredients, fuel and raw mix of cement, the blend of raw materials at quarries, the blend of coal at factories, the blend of ingredients for raw meal, coal dust fed into kilns, clinker coming out of kilns, milled cement and slag powder, as well as cement, slag powder and clinker ready to leave factory. These quality management measures together with accurate chemical analysis and inspection of physical properties ensure high pass rate of semi-finished products in various production stages, thereby assuring all products ready to leave factory will meet the quality requirements.

The Group has also established a quality management and research and development centre responsible for guiding and supervising different companies with respect to quality management; its laboratory and concrete testing centre is well equipped with all types of large-scale precision instruments to provide timely diagnosis, based on the test results, for issues related to raw material and fuel, production process, and concrete, as well as recommendations for improvement. All these ensure quality and consistency of Skyscraper brand cement, concrete and all other products, thereby gaining customers’ trust.
