Lead doors are specialized protective doors designed for high-radiation environments. Combining high-purity lead sheets with a reinforced structure, they effectively shield against ionizing radiation (such as X-rays and gamma rays), while maintaining both safety and durability. They have become essential protective equipment in the medical and nuclear industries.
I. Structural Design
Core Shielding Layer
Inside, 2-20mm high-purity lead sheets (≥99.99%) are embedded, seamlessly joined to ensure zero radiation leakage. The thickness of the lead sheets can be customized based on the level of protection (e.g., 3-5mm is commonly used in CT rooms, while nuclear power plants require 15mm or more).
Reinforced Frame
Outer Layer: Covered with 1.2-2.0mm cold-rolled steel sheets or antibacterial stainless steel, with an anti-corrosion surface treatment.
Inner Lining: Supported by a high-strength steel frame with a deformation resistance exceeding 1000kg.
Edge: Labyrinth-type sealing strips (made of silicone or EPDM) are installed, ensuring a radiation leakage rate of less than 0.1%.
Smart Accessories
Hydraulic Buffer Hinges: Support over 100,000 opening and closing cycles, with silent door closing.
Interlocking Device: Synchronizes with the radiation equipment, automatically shutting off the equipment if the door is not closed.
Observation Window: Lead glass window (lead equivalent to the door), 15-30mm thick.
II. Core Advantages
Top-notch Protection
The density of lead (11.34g/cm³) absorbs over 99% of gamma rays, providing protection far superior to concrete (which requires only 1/10 the thickness for the same effect).
Safety and Convenience
Automatic Start and Stop: Infrared/foot sensor switches prevent personal contact and contamination.
Emergency Release Mechanism: Manual release in the event of a power outage, meeting fire escape standards.
Extremely Long Lifespan: Weather-resistant, stable operation in environments ranging from -30°C to 60°C. No risk of oxidation failure of the lead plate, with a service life exceeding 20 years.
Environmental Compliance: Complies with GBZ 130-2020, "Radiation Protection Requirements for Diagnostic Radiology," and IAEA safety standards.
III. Application Scenarios
Medical
Hospital Radiology Departments (DR/CT Rooms), PET-CT Centers, and Radiotherapy Accelerator Treatment Rooms.
Dental Clinics: Protection against scattered radiation from small X-ray machines.
Nuclear Industry and Scientific Research
Nuclear Power Plant Fuel Storage Areas and Radioactive Waste Treatment Plants.
Laboratories: Nuclear physics research and isotope production workshops.
Special Industries
Industrial NDT Labs: X-ray Nondestructive Testing Chambers.
Security Inspection Systems: Cargo/Container Scanning Lanes.
Summary
Boasting military-grade shielding performance, modular smart design and full-scenario adaptability, our lead doors act as a vital line of defense for radiation safety. Beyond excellent radiation blocking capability, they convert complex protection demands into practical, user-friendly engineering solutions, protecting staff health and environmental safety at all times.

FAQ
Q: Do you support OEM production?
A: Yes. We can customize production based on your specifications (such as lead equivalent, dimensions, and material). Providing samples or design drawings will expedite the customization process.
Q: Can you accept small orders?
A: Yes. If the product is in stock, we can ship it immediately. If not, we will arrange flexible production scheduling (possibly combining production with other orders) to minimize lead times.
Q: Are samples free? How are shipping costs handled?
A: We can provide one free sample for standard products. Sample shipping costs must be prepaid. If you place a formal order, the shipping costs will be fully deducted from the order amount.
Q: How do we ensure transparency in order fulfillment?
A: We implement visual tracking throughout the entire process:
At the start of production:real-time photos of the workstations are sent;
After quality inspection:a radiation shielding performance test report is provided;
Before shipment: a video inspection is arranged for confirmation.
