Certification
As a leading Chinese fire door manufacturer, Guangdun Door Industry Co., Ltd. is proud to provide fire doors that comply with multiple global standards, including China’s 3C certification, the UL (Underwriters Laboratories) standard, and the WH (Warnock Hersey) certification. These certifications underscore our commitment to safety, quality, and reliability for fire-rated products. Below, we’ll explore these certifications and their relevance to the global fire door industry.
1. China 3C Certification: Setting the National Standard
The 3C certification (China Compulsory Certification) is a mandatory safety mark required for fire doors sold within China. This standard ensures that fire-rated doors meet stringent national safety criteria for durability, fire resistance, and material quality. At Guangdun Door Industry, our products consistently meet 3C requirements, providing 60-minute fire doors, 90-minute fire doors, and more to fit various applications.
For domestic projects, 3C certification guarantees a high level of trustworthiness. Additionally, Chinese fire door manufacturers like Guangdun offer cost-effective solutions without compromising on compliance and performance, making them an excellent choice for both local and international buyers.
2. UL Certification: The Gold Standard for Fire Safety
UL certification is globally recognized as the pinnacle of fire safety and quality assurance. With origins in the United States, UL standards such as ANSI/UL 10C and ANSI/UL 10B rigorously test the fire resistance performance of doors. These tests measure a door’s ability to withstand positive pressure fire tests and ensure optimal safety during emergencies.
Guangdun’s UL-rated fire doors are designed to meet international specifications. Whether for residential or industrial applications, our UL-certified products bring peace of mind to clients worldwide. Remember, when purchasing a fire door with a UL mark, always verify its authenticity via the official UL database to ensure compliance.
3. WH Certification: Bridging the US and UK Standards
The WH (Warnock Hersey) certification, developed under Intertek, is another key marker of high-quality fire-rated doors. WH certification adheres to both American and British standards, making it highly versatile for global projects. The headquarters for this certification is in the UK, with standards covering fire door testing and product durability.
For buyers targeting both Western and Asian markets, WH-certified fire doors from Guangdun Door Industry are ideal. Our company aligns production with WH standards to provide reliable solutions for cross-border compliance requirements.
4. Why Multiple Certifications Matter
