The New Era of Intelligent Door Control: Dashunhang Hardware Leads the Revolution of pre-embedded ground spring technology
Industry pain points give rise to technological innovation
At the 2024 Shanghai International Building Hardware Exhibition, a set of data sparked heated discussions: approximately 67% of traditional floor springs worldwide malfunction due to water seepage in foundation pits and aging of concrete, with an average annual maintenance cost of up to 1.2 billion US dollars. This situation is being rewritten by Chinese innovative enterprises - Dashunhang Hardware's newly released third-generation magnetic levitation ground spring system without pre-burial adopts the patented gravity self-compensation technology (Patent No. ZL2023 2 056789X), achieving an installation method that is completely independent of the concrete foundation.
Our solution can reduce on-site construction volume by 92%. When demonstrating on the spot, the technical director of Dashunhang emphasized, "In the renovation project of the Burj Al Arab in Dubai, this technology helped shorten the construction period by 40 days."
Three major technological breakthroughs are reshaping industry standards
Minimalist installation
The installation time has been compressed from the traditional 8 hours to 45 minutes through an aviation-grade aluminum alloy one-piece formed frame and an adaptive ground leveling module. Tests by the UAE certification body ESMA show that its dynamic load capacity reaches 1500kg, exceeding the EN1154 standard by 42%.
Intelligent operation and maintenance
The built-in NB-IoT sensor can monitor the movement trajectory of the door leaf and the cumulative usage times in real time. When the wear coefficient exceeds the threshold, it will automatically push a warning. Terminal 5 of Singapore Changi Airport has been integrated into the smart building management system.
All-climate adaptation
It adopts graphene composite lubrication technology to maintain torque stability in an environment ranging from -50℃ to 80℃. Measured data from the Arctic plant of Norilsk Nickel Group in Russia show that the low-temperature failure rate has decreased by 78% compared with traditional products.
The global market landscape is undergoing changes
According to the latest report from QYResearch:
The market size of pre-embedded ground springs will expand at a compound annual growth rate of 19.3%, reaching 2.75 billion US dollars by 2027
With its first-mover advantage, Dashunhang has achieved a market share of 29% in high-end projects in the Middle East, surpassing German Dorma
The new EU regulation EN179:2024 will mandate that floor springs be integrated with anti-tampering alarm functions. The company's related products have passed the CE review
Collaborative innovation in the industrial chain is underway
Zhou Jing, the secretary-general of the China Building Metal Structure Association, pointed out: "This trend of 'Internet of Things for hardware components' is driving the door, window and curtain wall industry to shift from competition in individual products to competition in system services." Recently, Dashunhang has collaborated with Huawei Cloud on a digital twin platform for door control, which enables real-time traceability of global project installation data. Currently, 17 of the top 50 real estate developers have been connected to this system.
