About us
Practical IoT technology for safer, better-managed construction sites.
Founded in Jinan in 2018, ZN is an IoT solution provider for smart construction sites, supplying the devices, the platform and the installation delivery that make site safety measurable and manageable.
Who we are
A one-stop IoT partner for smart construction sites.
ZN Safety Technology was founded in Jinan in 2018, formerly Shandong Shuda Safety Technology, with registered capital of RMB 10 million. We focus on IoT solutions for smart construction sites and deliver one workflow covering hardware devices, the platform system and installation handover. Our product range covers three families: heavy-machinery safety protection, including tower crane monitoring, construction hoist monitoring, hook visualization, anti-collision and unloading platform monitoring; site environment and workforce management, including dust and noise monitoring, automatic spray control, smart water and power meters, face-recognition gates, personnel positioning and real-name management, and helmet-removal detection; and IoT data infrastructure, including site data-collection terminals, edge-computing gateways, and sensors for wind speed, tilt, load, height and radius.
Our culture
Empowering construction with intelligence.
Make engineering safer and more efficient with intelligent technology.
To become the most trusted smart-engineering enterprise.
Six core values
The principles behind every delivery.
Love
Love for ourselves, our families, our partners, our customers and the society we work in.
People first
Users first, teams first, families first.
Responsibility
Responsibility to the company, to each project and to the results we deliver.
Teamwork
Trust first, treat people as people, and stay worthy of that trust.
Striving
Keep learning, refine every detail and become the expert customers rely on.
Self-review
Review honestly, criticise ourselves openly and keep correcting what needs to change.
Our core strengths
Broad product line, flexible configuration, solid delivery.
A broad product line
Machinery safety, environmental monitoring, workforce management and data collection in one place, covering most IoT device needs on a smart site and removing the burden of dealing with many suppliers.
Flexible solutions
Standard devices or tailored combinations: from a single tower crane monitoring terminal to a group-wide platform managing multiple projects, matched to budget and site reality.
Solid delivery on site
Our own implementation team deploys quickly in complex construction environments and commissions what we sell. We do not hand over a box and walk away.
Why choose us
We understand the site, the project process and the people running it.
We know construction sites
Our team has worked in construction safety for years and understands how state-owned and central enterprises manage projects and how site crews actually work, which keeps communication short and direct.
We bring resources
Broad industry relationships help customers connect quickly with localised service and supply-chain support.
We are trusted
We serve state-owned and central enterprise builders, equipment leasing companies and local safety supervision stations, with more than 200 customers served and a fast, flexible response.
Our philosophy
Practical IoT technology that makes construction safety visible and controllable. No flashy concepts, only solutions that genuinely work on site.
The integrated platform
One platform to manage every project under construction.
- 01
Centralised multi-project supervision
See live operating data from every active project in one platform, including equipment status, alarms, environmental indicators and workforce attendance, instead of travelling from site to site.
- 02
Alarms and closed-loop handling
When a tower crane is overloaded, dust exceeds the limit or someone enters a hazard zone, the platform pushes a real-time alarm and tracks the issue from detection to resolution.
- 03
Statistics and analysis
Automatic equipment run reports, alarm trend analysis and attendance statistics give project and safety decisions a factual basis.
- 04
Mobile collaboration
A companion app and mini-program let site managers check data, receive alarms and approve inspection tasks from anywhere.
Start from the site, not from a product list.
Tell us what your project needs to achieve, whether machinery safety, environmental monitoring, workforce management or platform integration, and we will propose a configuration that works on site.
