三井金属エンジニアリング Product Lineup

We have a wealth of experience supplying radiation shielding materials for hospitals and medical facilities! Lead has effective shielding performance against gamma rays, beta rays, and X-rays. It has high absorption performance, allowing for thinner shielding materials, and can be easily processed on-site with cutters and saws, offering excellent workability. We also provide lead sheets, lead tapes, lead composite boards (such as gypsum boards and plywood), and protective room fixtures (doors and windows). With our extensive product range, they can be widely used for the floors, walls, and ceilings of protective facilities.

With the development of the nuclear power industry and the advancement and widespread use of radiation technology in the medical field, there is a strong demand for human protection against radiation and measures to combat environmental pollution. On the other hand, noise troubles are also on the rise, increasing the importance of soundproofing to create a quiet living environment. Lead has a high density and possesses both sound attenuation and radiation absorption properties. Onshat is a high-purity lead sheet that maximizes these excellent characteristics of lead. We also offer lead sheets, lead tapes, and lead composite boards (such as gypsum boards and plywood). 【Features】 ○ Wide width and long length ○ Excellent durability, maintenance-free material with a semi-permanent lifespan ○ Achieves high-performance soundproofing and radiation protection at low cost ○ Can be processed with common tools (such as cutters and saws), including composite boards. Installation can be done using standard construction methods.

The non-destructive testing room and the electron beam irradiation processing panel use radiation, so lead is used as a protective material. Our company provides total support from design to manufacturing and installation. We accept designs and construction tailored to the site, so please feel free to contact us! Applications: ○ Non-destructive testing room ○ Electromagnetic irradiation processing panel ○ Various training facilities

With the spread and advancement of electronic technology, there is a growing tendency for electromagnetic interference (EMI/RFI) to increase in various fields. The solution to these troubles is radio wave shielding by Emishat. Emishat effectively blocks the intrusion of electromagnetic waves into indoor environments and the release of indoor-generated electromagnetic waves into the external environment, thanks to its excellent shielding performance and functionality that covers a wide range of frequencies. It creates an electromagnetically harmonious human space where electronic devices and electrical equipment do not interfere with each other. 【Features】 - High conductivity - Ultra-thin and ultra-lightweight, making handling, processing, and installation easy, thus reducing labor and shortening construction time - Excellent electromagnetic shielding effect across a wide frequency range - Wide width and long length - No risk of corrosion or degradation of conductivity - Maintenance-free - Achieves high-performance electromagnetic shielding

We have applied a non-chromate treatment to hot-dip galvanized steel sheets and independently developed a coating that enhances adhesion to the zinc coating. We have conducted various tests, including performance tests of the coating film and long-term rust resistance tests (atmospheric exposure tests and salt spray tests), to confirm its corrosion resistance. Our corrosion-resistant drum can, developed as a storage container for low-level radioactive waste, has been used at various nuclear power plants for 30 years since 1982, with approximately 50,000 units delivered. We also offer shielding drum cans with radiation shielding performance (lead and concrete lining). For more details, please contact us or download the catalog.

The construction and operation of nuclear-related plants require advanced technology and materials for radiation protection. Rayshut is a lead shielding material developed to meet these demands. We offer a wide range of products, including lead sheet mats, lead wool, lead pellets, lead blocks, and lead processed products.

By using our independently developed specialized auxiliary materials "fire-resistant felt" and "fire-resistant sheet," we have obtained certification for a fire-resistant wall structure with a one-hour fire rating using "reinforced gypsum board 12.5mm," making it the first of its kind in the industry. It is ideal for fire-resistant walls in hospitals, such as X-ray rooms and CT rooms, where X-ray protection is necessary. For more details about the product, please feel free to contact us.

Our non-ferrous smelting technology and engineering are also utilized in the field of shielding and soundproofing materials. "Emishat" is designed for electromagnetic shielding, "Onshat" focuses on soundproofing and radiation protection related to medical applications, and "Reishat" is primarily aimed at radiation protection in the nuclear industry. We provide a comprehensive range of services related to shielding and soundproofing materials, from the supply of materials such as copper foil, zinc foil, and lead, to design, construction, and after-sales service. Applications: Radiation shielding protection for radiation detectors within nuclear power plant buildings [lead shielding for gas samplers / lead blocks for dust samplers] and long-term storage containers for high-level radioactive waste [lead shielding drums]. Electron beam irradiation processing equipment. X-ray non-destructive testing equipment. Electron beam radiation rooms. Various research facilities. X-ray and radiation protection related to medical applications. Industrial lead panels. Soundproofing in various facilities.

■ Onshat Radiation Protection Door This is a radiation protection door that achieves "high safety" required in medical facilities and similar environments. It supports the creation of a safe space with stable quality, even in environments where radiation measures are necessary. We can customize production according to site conditions. 【Examples of Use】 ● Hospitals (X-ray rooms, CT rooms, etc.) ● Health check centers ● Research facilities ■ Please consult with us first "Is this size feasible?" "What will the finish be?" "What is the delivery time?"
