The US NFRC Energy Efficiency Certification, the Australian AS/NZS Safety Standard Certification, and the EU CE Certification have all been successfully attained by Greborn, a prominent brand in China's door and window market. Greborn's products have attained the world-leading level in key indicators like quality, energy efficiency, and safety, making it one of the few domestic door and window companies to simultaneously obtain these three international authoritative certifications. This accomplishment lays a strong foundation for Chinese aluminum alloy doors and windows to enter the global market.

This time, the EU CE Certification demonstrates that its products fully satisfy the EU market's access requirements by covering a number of strict indicators, such as structural stability, environmental friendliness of materials, and sound and thermal insulation performance. Energy-saving metrics like the thermal transmittance and shading coefficient of windows and doors are subject to authoritative testing by the US NFRC Certification. Greborn's products can effectively reduce building energy consumption by over 30% thanks to their composite structure of high-purity aluminum alloy profiles and double-layer insulating Low-E glass, which far surpasses certification standards in energy efficiency. Safety performance in harsh weather conditions is the main focus of the Australian AS/NZS Certification. Greborn's doors and windows meet Australia's stringent safety regulations with their waterproof and anti-prying qualities and a wind pressure resistance rating of over Class 9 thanks to the optimization of hardware accessories and sealing technology.
