Double Open Lead Door is a high-performance shielding solution designed for radiation-controlled spaces, combining robust radiation protection with fire safety compliance. Manufactured with 99.994% pure lead ingots and industrial-grade structural materials, it effectively blocks X-rays, gamma rays, and electromagnetic radiation while meeting strict fire resistance standards. Available in manual, automatic, induction, remote-controlled, or button-operated models, this door offers flexible customization for size, color, and lead equivalent—making it suitable for nuclear magnetic resonance (NMR) rooms, industrial shielding facilities, medical radiology departments, and laboratories. Its double-open design ensures efficient traffic flow, while integrated safety features (e.g., self-closing devices, intumescent seals) prioritize personnel protection in emergency scenarios.

Exceptional Radiation Shielding:
High-purity lead lining provides reliable protection against X-rays, gamma rays, and electromagnetic radiation—critical for medical and nuclear industry applications.
Dual Fire & Radiation Protection:
Complies with international fire safety standards (e.g., NFPA 99, Hong Kong Building Regulations) with self-closing devices and intumescent seals that block smoke and flames.
Flexible Customization:
Adaptable size, color, and opening modes cater to diverse facility needs, from small laboratory doors to large industrial shielding room entrances.
Durable & Low-Maintenance:
Industrial-grade outer panels and corrosion-resistant lead lining ensure long service life, with minimal maintenance required.
User-Centric Safety:
Induction and automatic models reduce physical contact, while clear labeling and certification simplify compliance checks.
Medical Facilities:
Radiology departments, CT scan rooms, radiotherapy centers, nuclear medicine labs, and NMR shielding rooms.
Industrial Settings:
Industrial shielding rooms, non-destructive testing areas, nuclear engineering facilities, and radioactive material storage zones.
Laboratories:
Research labs handling radioactive substances, electronic device testing rooms (with electromagnetic shielding), and chemical analysis facilities.
Specialized Buildings:
Nuclear power plant control rooms, radiation therapy clinics, and industrial manufacturing facilities requiring radiation isolation.
Medical lead doors must comply with fire resistance ratings (FD30 or FD60) to contain fire and smoke. They also require intumescent seals (expand with heat to block smoke/flames), self-closing devices, permanent certification labels, and integration with building fire alarm systems (automatic closing when alarms trigger). Relevant standards include NFPA 99 (US) and Hong Kong’s Building (Construction) Regulations.
Automatic (induction or remote-controlled) lead doors eliminate the need for personnel to touch door handles in radiation zones, reducing cross-contamination risks. They also feature quick-closing mechanisms to minimize radiation leakage during door operation, ensuring consistent shielding performance.
Yes. We offer fully customizable size options to fit extra-large openings (e.g., for industrial shielding rooms or equipment entry). The door structure is engineered to maintain radiation shielding integrity and structural stability, even for large dimensions.
Regularly inspect the lead lining for cracks, dents, or wear (replace if damaged); check intumescent seals for deterioration; test self-closing and interlock systems monthly; and clean the door surface with non-abrasive materials to avoid scratching the outer panel or lead lining.
