Huangshi Jindun has been shortlisted as one of the top ten brands of passive doors in China for 2025, leading the new trend of energy-saving security

Recently, the list of the top ten brands of passive doors in China for 2025 was officially announced. Huangshi Jindun, with its technological accumulation and market performance in the field of passive doors, successfully made the final list and became one of the brands that have attracted much attention in the industry.

As a brand under Zhejiang Kaihua Door Industry, Huangshi Jindun has been rooted in the Niubeijin Industrial Zone in Wuyi, a neighboring county of Yongkang, Zhejiang, known as the "Door Capital of China," since its establishment in 2009. Relying on local industrial advantages, it focuses on the research, development, and production of doors. Being shortlisted for the Top Ten Brands is a recognition of its deep cultivation in the field of passive doors over the years. Huangshi Jindun's passive system armor doors adopt advanced thermal insulation and soundproof materials and innovative structural designs. By optimizing the material and thickness of the door's thermal insulation layer, coupled with precision sealing technology, they effectively block heat conduction between indoors and outdoors, reduce building energy consumption, and create an energy-saving and comfortable living environment for users.

In terms of safety performance, the product integrates the characteristics of industrial explosion-proof doors, utilizing special industrial cast aluminum material, paired with Sino-German joint venture brand locks and Taiwanese imported 304 stainless steel hinges, to establish a six-level joint defense architecture. This comprehensive approach enhances the door's anti-theft and durability capabilities, from external protection to internal support. In the future, Huangshi Jindun will continue to increase its investment in technological research and development, driving the passive door industry towards a more energy-efficient and safer direction.
