Following the evolving international standards for fire doors, China's fire door industry is also under pressure to innovate and align itself with world standards.

As the corporate brand of ASSA ABLOY, Longdian made this breakthrough with the technological breakthrough of glass-insulated fire door. EN insulated fire doors in the design and development, there is no simple focus on the European standard itself, but to fully digest and contrast European standard EN1634-1, GB GB12955-2008, British standard BS476-20 & 22, not only from the test details Starting with special attention to the parallel production of future batch products and realizing the design and production of the current standard steel door products of Dragon Power to meet the 120-minute heat insulation function requirements of EN1634-1.

Long 120 minutes glass fire door has passed the Hong Kong RED laboratory test, and also won the Tseung Kwan O Digital Center in Hong Kong thermal insulation fire door project orders for more than 400 sets. Taking advantage of its geographical proximity to Hong Kong, Dragon Power has seized the opportunity to bid for some large-scale projects in Hong Kong and is actively seeking opportunities for cooperation in Hong Kong airport and subway projects. Wang Jinxing, General Manager of Dragon Power introduced: "The successful test of EN120-minute heat-resisting fire-proof door is an important testament to the function and technology of Longdian in the heat-resisting fire-proof door. , Nuclear power and other areas and areas originally controlled by foreign standards, all the original technical specifications and design standards are required to move closer, or the conversion of international standards. The successful development of Longhua's European standard 2-hour heat-insulated fire doors is one of these projects Extremely important bargaining chip is one of the most competitive conditions. "

After joining ASSA ABLOY, Shenzhen Longdian Technology Industrial Co., Ltd. has paid more attention to the international market and continuously explored and developed the field of fireproof door products.
