Dashunhang Hardware has released a new generation of pit-free floor springs, leading the wave of intelligent building hardware

With the global construction industry moving towards high efficiency and intelligence, the traditional installation method of floor springs is undergoing significant changes. Dashunhang Hardware, a leading domestic manufacturer of building hardware, recently released a brand-new generation of floor spring system without digging pits. With revolutionary installation technology and intelligent functions, it provides more flexible and reliable door control solutions for commercial buildings, public facilities and high-end residences.

Technological breakthrough: Farewell to traditional excavation, installation efficiency increased by 70%

Traditional ground springs need to be pre-buried underground, which is complex to construct and damages the ground structure. The DSE series of pit-free floor springs launched by Dashunhang this time adopt a modular suspension design. They can be directly installed on the ground through patented hydraulic buffering technology (with 12 domestic and international patents already obtained), and have a load-bearing capacity of up to 1200kg. They are suitable for various scenarios such as glass doors and metal doors.

"This technology has solved the installation problems in the renovation of old buildings," said the technical director of Dashunhang. "In a hotel project in Dubai, we completed the installation of 10 sets of floor springs in just 3 hours, saving 70% of the time compared to the traditional method."

Three core advantages seize the market

Minimalist installation: No need to damage the ground, reducing construction costs and project duration

Intelligent adaptation: Built-in pressure sensor, which can be linked with the building management system to achieve door status monitoring

All-environment applicability: Customized versions with anti-corrosion properties (for coastal areas) and low-temperature resistance (-40℃) are launched

The global market performed outstandingly

According to the company's disclosure, in 2023, the export value of Dashunhang's floor spring products exceeded 8 million US dollars, with a year-on-year growth of 300% in the Middle East market. They were successfully applied in international projects such as the venues of the Qatar World Cup and Singapore Changi Airport. At present, the product has passed certifications such as EN1154, CE, and TUV, and meets the building safety standards of the European Union and North America.

Industry evaluation

Technical experts from the International Access Control Association (IDAA) commented: "The pit-free floor spring is an important innovation in the access control field in the past five years, especially having significant advantages in the renewal of existing buildings."

Future layout

Dashunhang announced that in 2024, it will collaborate with universities to develop an AI self-learning floor spring system. By optimizing door speed control through big data, it will further reduce energy consumption. The company plans to build a new production line in Southeast Asia, with an expected annual production capacity of 500,000 sets.
