Quality Control
At Ulianglass, every glass product undergoes strict inspection and testing procedures to ensure safety, durability, and compliance with international architectural standards.
Our quality control system covers tempered glass, laminated glass, insulated glass, and curved glass applications for global projects.
Professional Glass Testing Procedures
1. Fragmentation Test
Tempered glass is tested to ensure safe breakage patterns and compliance with international safety standards.
2. Impact Resistance Test
Glass strength and structural performance are verified under simulated heavy impact conditions.
3. Dew Point Test
Insulated glass units are tested to ensure sealing stability and anti-fogging performance.
4. UV Resistance Test
Coating durability and sealant performance are evaluated through long-term UV exposure testing.
5. Light Transmittance Test
Visible light transmission is measured to meet facade and energy-efficiency requirements.
International Quality Standards
Our factory follows strict testing standards to ensure reliable performance for architectural glass applications worldwide.
Testing standards include:
- GB/T Standards
- EN Standards
- ASTM Standards
- CE & SGCC Requirements
Why Quality Control Matters
