Our management places a strong emphasis on quality, especially in the appearance, safety and functional aspects of our products. Our quality control encompasses stringent quality control at every stage of our production process and continuous process improvement.

We station our quality assurance personnel in our production plants to carry out stringent quality checks and controls at every stage of the production process.

Our products have complied with the national standards set by the National Construction Materials Test Center.

In addition, our manufacturing facility in Jiangyin, Jiangsu Province, PRC was certified and awarded the ISO 9002 standard in 2000 by Shanghai Audit Center of Quality System and has since continued to maintain this certification. Our production process has also been certified and awarded the ISO 9001:2000 in 2003 by Beijing Zhonglian Certification Center.

In November 2006, we received the prestigious Certificate (产品质量国家免检证书) from the State General Administration of the People's Republic of China for Quality Supervision, Inspection and Quarantine (国家质量监督捡验捡疫总局) ("State General Administration").

This highly regarded and prestigious certificate grants our products exemptions from quality supervision and inspection.
