"Water Leakage Detection System for Steel Material Storage Locations" - Instantly Visualizing the "Invisible Risks" at Steel Storage Sites - Grid Link Co., Ltd. - February 24, 2026

Avoid significant quality deterioration at the steel storage site.

In factories and warehouses storing steel plates, coils, and bars, water exposure from condensation, rain leaks from the ceiling, and melting snow can lead to significant quality deterioration. Once moisture adheres, it can result in: ● The occurrence of red rust and white rust ● Decreased surface quality ● Increased costs for re-polishing and reprocessing ● Shipping delays ● Claims and loss of credibility, leading to substantial damages. However, water exposure often occurs quietly from areas that are difficult to monitor, such as near the ceiling during nighttime or unmanned hours. Do not overlook that "initial drop." This system uses highly sensitive sensors installed in the storage area to instantly detect moisture. It notifies of abnormalities in real-time, enabling prompt action before damage escalates. ■ Main Features ✅ Immediate detection of trace amounts of moisture ✅ Responds to condensation, leaks, and melting snow ✅ Continuous monitoring even during unmanned hours ✅ Alarm, email, and remote notification capabilities ✅ Can be retrofitted to existing warehouses From visual inspections to "constant monitoring" In traditional patrol inspections, there is a time lag between occurrence and discovery. This system monitors 24/7, minimizing damage. It prevents situations where "by the time you notice, a wide area has already rusted."

Monitors the risk of condensation, which can cause rust on steel materials, corrosion on aluminum materials, and uneven paint application. By calculating the dew point temperature from the surrounding environmental temperature and humidity, and monitoring the difference between this and the surface temperature of the monitored objects (products, walls, ceilings, floors, etc.), the risk of condensation is assessed. Notifications are sent via email, patrol lamps, and automated voice calls according to the risk level (caution / countermeasures / alarm) to prompt quick responses such as ventilation or relocation of stored items. As an option, it is also possible to automatically control a blower. *Dew point temperature: The temperature at which condensation occurs on the target object (products, walls, ceilings, etc.), calculated from the surrounding environmental temperature and relative humidity. ▶ For quotation requests, please contact us via [Web Inquiry] ◀ ▶ For more details, please download the [Catalog] ◀

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who wish to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. You can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520" depending on the application and installation location. 【Recommended for such places!】 ☑ Entrance facing a busy corridor ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passages ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing, contributing to energy-saving by minimizing wasteful power consumption ● Equipped with a light touch function, allowing the door to open and close just by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.
