Dayang Renews ISO 9001:2015 Certification Across All Five Factories

We are pleased to announce that all five Dayang Glass manufacturing facilities have successfully renewed their ISO 9001:2015 Quality Management System certifications following a comprehensive external audit conducted in April 2026.

Audit Highlights

The audit covered all production lines across our Shenzhen and Guangdong facilities, including:

• Curved glass hot-bending and tempering
• Flat tempering and heat-strengthening
• Laminating and IGU assembly
• Digital printing and ceramic frit application
• Art glass and decorative processing

Zero major non-conformances were recorded — a result of our continuous improvement programme introduced in 2023.

What This Means for Buyers

• Documented, reproducible processes at every production stage
• Traceability from raw glass batch to finished unit
• Systematic corrective action on customer complaints
• Annual surveillance audits to maintain certification

Our full certificate portfolio — ISO 9001, CE marking, SGCC, and product-specific test reports — is available to qualified buyers on request.
