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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

For domestic hospital general contractors, construction firms, decoration companies and medical construction groups, we offer multiple cooperation models: project subcontracting, bulk material supply, full EPC general contracting, and long-term regional channel agency. We deploy local construction teams nearby to shorten construction cycles and cut transportation costs.

Overseas cooperation options include full-container FOB/CIF bulk supply, dispatched engineer construction guidance for overseas infrastructure projects, technical training for local overseas construction teams, and long-term overseas project maintenance services. We collaborate with established international logistics providers with multi-port delivery capabilities, supporting project subcontract delivery for overseas general contractors and multi-currency settlement.

We have set up a dedicated overseas foreign trade technical team providing 7×16-hour Chinese-English bilingual online technical support. Services include foreign-language drawing deepening, process translation, working condition adaptive modification, and construction scheme adjustment in compliance with local building codes of different overseas countries.
