a.Inspection and Control of incoming raw materials: According to the chemical content, raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process: During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Inspection of product Standardization of quality of each product by process control and experimentation .
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management. Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
By Following the above steps we maintain the quality within specification so that the materials perform as per expected norms. Qualified and experienced engineers back our quality assurance system. We have the most modern test facilities for precise testing at each stage. Further, regular quality audit carried out ensures product quality within required norms.ltd has been awarded ISO 9001 Certification .
