● The aluminum sheet, reinforced with glass fiber and double-sided aluminum foil, eliminates the need for construction with copper mesh and copper foil, which are susceptible to corrosion. It exhibits unprecedented strength, making it less likely to develop holes during installation or cracks due to bending, unlike conventional products. The joints and holes are reinforced with SS tape of the same material, enhancing workability and providing excellent shielding performance. ● The shielding performance has been proven by numerous electromagnetic wave shielding construction achievements. ● As a durable and easy-to-install shielding material that replaces the difficult-to-handle copper foil in EEG, EMG, and hearing test rooms, the moisture-resistant aluminum sheet shield is easy to maintain, durable, requires no special skills, and is relatively easy to install in interior construction, making it ideal for new builds, renovations, and maintenance work.

● Before the measures were implemented, the electronic tags (RFID) on the apparel store side were being read by the reader on the back-end side, causing disruptions in operations. However, by spatially separating them with a non-combustible aluminum shield sheet partition (constructed on the back-end wall to prevent multipath interference, with ceiling installation examples depending on the environment), we reduced the impact of mutual interference and resolved the issue, and we are currently expanding renovations to all stores. ● By utilizing RFID and electronic shelf labels together, we can automate necessary parts, allowing us to allocate limited personnel to areas where human involvement enhances corporate value and the significance of the store, thus achieving true labor reduction. Recently, due to the pressure on radio waves leading to frequency shifts and reconfigurations, as well as an increase in RFID users and other wireless devices, cases of acquired radio interference and other obstacles have been observed. However, considering the characteristics of RFID, what is expected is not just labor reduction. ● The non-combustible certified aluminum electromagnetic wave shielding sheet used has obtained F☆☆☆☆ certification and fireproof certification (non-combustible: NM-1776). Its high shielding performance and durability make it user-friendly, and because it can be relatively easily installed in general interior construction, it is expanding its range of applications in various uses where specialized skills were previously required.

1) "Wireless LAN Access Point Storage Box" - Controls the direction of radio wave emission to prevent interference, and prevents interference caused by reflections on metal floor surfaces within the ceiling, making it essential for ceiling-mounted access points. - Allows for easy adjustment and relocation of the AP position after installation. - Thickness can be adjusted according to the frequency band used, enabling optimal radio wave absorption. 2) "Heat-Reflective Transparent Electromagnetic Wave Shield Window Film" - Reflects over 90% of infrared rays (solar heat) contained in sunlight and cuts 99% of ultraviolet (UV) rays. - Offers a high light selectivity with a light efficiency of 1.4 (for 73FG), which is unmatched by other companies, demonstrating high heat-reflective properties while remaining transparent. It is a high-performance mirror type that can reflect infrared rays, with a visible light reflectance of less than 10%, preserving appearance, and provides an electromagnetic wave (electric field wave) shielding effect of 25-30 dB. - When used in combination with the adjustment of the installation position of the "Wireless LAN Access Point Storage Box," high attenuation effects are observed in cases of exterior walls: metal curtain walls / structural floors: metal deck plates, etc. 3) In cases where the exterior wall is RC (reinforced concrete) and ALC (autoclaved lightweight concrete), there is no shielding performance, so a composite measure involving the installation of non-combustible aluminum sheets will be implemented.

We offer a one-stop solution for the development of electromagnetic wave shielding materials at our in-house research institute, manufacturing at our own factory, measuring materials and methods in our in-house research facility's "anechoic chamber," design, electromagnetic wave shielding construction, and electromagnetic wave measurement (upon handover).

We have launched a "flame-retardant electromagnetic wave shielding membrane material" that demonstrates electromagnetic wave shielding performance even in outdoor environments and can also be used as tent material. We have developed a flame-retardant shielding membrane material that has electromagnetic wave shielding performance in outdoor environments and can independently construct structures such as tents. It can be used in a wide range of fields, including logistics and defense. 【Features】 - Electromagnetic wave shielding membrane material that is "flame-retardant" and "can be used independently outdoors" - Can be processed similarly to general tent materials - Electromagnetic wave shielding performance remains unchanged even when exposed to wind and rain - Can be used for construction purposes due to its flame-retardant properties. - Intended uses: - Radio wave shielding for factories, warehouses, and logistics hubs using RFID - Shield tents for operational command in the defense sector, shield covers for electronic equipment protection - Concert tents, circus tents, and expo pavilions that use wireless radio and wireless microphones inside - Drone training grounds where interference from radio waves needs to be eliminated *For more details, please contact us or view the PDF materials available for download in the catalog.
