Product Description

General Introduction of Mingren Lead Shielding Doors

The company’s lead door series covers electric sliding doors, airtight protection doors and heavy-duty industrial anti-radiation doors, fully adapting to X-ray rooms, DR and CT rooms, intervention operating rooms, radiotherapy departments, dental clinics, industrial flaw detection workshops and ray laboratories. All doors adopt high-purity lead plates with dense and seamless shielding structure, effectively preventing ray leakage. The optimized maze sealing design at the edges ensures stable and safe shielding performance in long-term use.

The door body is constructed with reinforced steel keel and high-quality exterior materials including stainless steel and electrostatic spray steel plate, featuring strong deformation resistance, corrosion resistance and easy cleaning. Equipped with silent driving system, buffer structure and fully sealed rubber strips, the doors operate smoothly, quietly and tightly. Electric models are integrated with intelligent interlock control, sensor access, emergency manual opening and radiation warning system, which greatly improves operational safety and meets standardized medical management requirements.

Mingren provides one-stop services including on-site measurement, customized production, professional installation, inspection and after-sales maintenance. With stable quality, standardized process and complete qualification documents, Mingren lead doors have become a trustworthy choice for hospital renovation, new construction projects and industrial radiation protection engineering.

FAQ

Q：

What authoritative qualifications does your company possess? Do your products meet domestic and international standards?

A：

Our purification products strictly comply with national domestic standards for hospital purification projects and industrial cleanroom codes. The shielding parameters of our radiation protection products exceed national standard limits. The full product range is equipped with factory inspection reports and third-party test certificates. Export products are certified with CE marks, fully satisfying compliance requirements for domestic hospital EIA acceptance, overseas customs clearance, and overseas project supervision audits. Meanwhile, we hold complete general contracting qualifications for purification and radiation shielding projects, capable of delivering full EPC turnkey contracts.

Q：

What are your core business scopes? Can you undertake domestic and overseas projects?

A：

Our two core business segments cover full R&D and manufacturing of purification equipment, turnkey purification engineering, full-series radiation shielding products, and special radiation shielding projects. Our domestic business covers all provinces and municipalities nationwide. We also hold complete foreign trade export qualifications. Our products and engineering technical services can be deployed across Southeast Asia, the Middle East, Africa, Central Asia, Latin America and other global regions. We provide full overseas solutions including bulk export supply, dispatched overseas construction guidance, and localized on-site training.

Q：

Do you own independent production workshops or outsource manufacturing?

A：

We operate a fully self-owned industrial production park in Liaocheng, with multiple independent production lines for clean doors, color steel purification panels and lead shielding components. We conduct independent raw material procurement and deep processing with no outsourced manufacturing. Full-process quality control is implemented from raw materials to finished goods, supporting mass customized production.

Q：

What types of purification products do you offer? Is non-standard customization available?

A：

Our flagship purification products include airtight clean doors, automatic medical airtight doors, purification color steel plates, purification air conditioning units, stainless steel clean hardware components, and clean enclosure profiles. We support non-standard customization on dimensions, special structures, anti-corrosion and antibacterial processes for cleanliness levels ranging from Class 100 to Class 100,000. Our products are widely applied in hospital operating rooms, ICUs, PCR laboratories, biopharmaceutical factories, electronic dust-free workshops and other scenarios.

Q：

What purification projects can you undertake? What is your complete service workflow?

A：

We deliver general contracting purification projects for hospital operating rooms, ICUs, central sterile supply departments, endoscopy centers, medical laboratories, as well as new construction and renovation of industrial dust-free workshops. Our one-stop EPC workflow: Site Survey → Cleanliness Level Scheme Design → Drawing Deepening → Component Manufacturing at Our Factory → Standardized On-site Construction → System Commissioning → Third-party Inspection & Acceptance → Permanent File Establishment for Long-term Maintenance.

Q：

What is the typical construction period for purification projects? How is after-sales service guaranteed in the long run?

A：

The construction period is calculated according to project area and cleanliness grade. Small-scale ward projects take 7–15 working days. For full-floor operating rooms or large industrial workshops, we will issue a dedicated detailed construction schedule. Domestic clients enjoy 24/7 online emergency after-sales support and periodic free on-site inspections. Permanent project files are created for all purification projects with warranty periods superior to common industrial standards.

Q：

What radiation shielding products are available? How to select products for different radiation scenarios?

A：

Our shielding product portfolio includes motorized/manual lead shielding doors, high-purity lead sheets, radiation-proof lead glass, barium sulfate shielding paint/sand, mobile lead screens, and dedicated shielding components for industrial flaw detection. Our technical team calculates precise lead equivalence for different radiation doses generated by DR, X-ray, CT, mammography, radiotherapy, nuclear medicine, industrial non-destructive testing and university research laboratories, developing customized shielding schemes to avoid insufficient protection or material waste.

Q：

Can you assist with radiation EIA acceptance upon completion of radiation shielding projects?

A：

Yes. After full completion of radiation shielding works, we provide complete as-built documentation and shielding performance test reports, assisting clients in coordinating with environmental authorities for radiation EIA approval and department practice qualification inspection to streamline complicated document submission work.

Q：

How do you guarantee the quality of lead raw materials? Is there any risk of adulteration or downgraded materials?

A：

We exclusively adopt high-purity virgin lead and reject recycled impure lead materials. Each batch of raw materials comes with material test certificates. Finished products undergo secondary random radiation shielding sampling tests. On-site shielding performance testing is available post-construction. We guarantee unconditional rework and rectification if test parameters fail to meet requirements.

Q：

Are your quotations fixed or project-customized?

A：

All purification and radiation shielding products & projects adopt project-specific customized quotations. Product pricing is determined by dimensions, material craftsmanship and order quantity. Engineering quotations contain detailed itemized pricing based on site area, cleanliness level / radiation equivalence, construction environment and technical difficulty. Our quotations are fully transparent with no hidden extra charges.

Q：

Will construction costs surge significantly for off-site projects?

A：

We have established cooperative construction outlets across the country. Off-site projects adopt local construction teams supervised by headquarters technical managers, which drastically reduces travel and labor premium costs. Our nationwide standardized pricing system prohibits arbitrary price hikes based on geographical locations.

Q：

Are there preferential policies for long-term bulk procurement?

A：

We launch tiered bulk pricing, annual rebate policies, priority production scheduling and free technical scheme design for general contractors, long-term distributors and fixed overseas foreign trade clients. Detailed terms can be finalized through business negotiations for long-term cooperation agreements.
