We will exhibit at the 10th International Drone Exhibition! (Tokyo Big Sight)

[Inspection Support Technology Performance Catalog] Introducing structural inspection technologies utilizing drones, pole cameras, and AI image analysis technology.

We would like to introduce a technology that supports structural inspections consisting of "non-GNSS environment compatible drones," "pole cameras," and "image analysis software for extracting damage." *Technical overview materials are available in the catalog section at the bottom of this page. Additionally, this document has been created for those who have downloaded it, to provide an overall understanding of our company's technology. Since it does not contain detailed information, please contact us through the inquiry section of this page or the email address listed at the end of the presentation materials if you require specific explanations. *It is also possible to conduct individual briefing sessions using web conferencing systems.

• Non-destructive testing

A inspection robot that can automatically avoid obstacles such as eaves and windows, addressing worker safety and labor shortages! It is also capable of close visual inspection using a camera and floating surveys using a tapping device.

This is a robot developed through joint research between Toyohashi University of Technology and Sanshin Kenzai Kogyo, designed to elevate and inspect exterior walls, with the development concept focusing on ensuring worker safety, addressing labor shortages, digitizing inspections and surveys, and securing flexibility in application through modularization. Currently, we are conducting verification tests aimed at commercialization. 【Development Concept】 ■ Ensuring worker safety ■ Addressing labor shortages ■ Reducing costs of inspections and surveys ■ Securing flexibility through modularization of inspection equipment 【Benefits of Implementation】 ■ Capable of carrying inspection equipment and using cameras and impact testers to diagnose deterioration and detachment of exterior walls ■ Enables high-altitude inspections without the use of scaffolding or gondolas ■ Eliminates concerns about dangerous work, costs, stress, and aesthetics ■ Allows inspections of bridge decks without using crane trucks for bridge inspections *This is a robot currently under joint research and development.

• Structural Survey

No differences in sensory perception among people! Development of a "floating" inspection method as a substitute for sound inspection.

At SANSIN Construction Materials Co., Ltd., we aim to provide accurate inspections for structures (mortar) such as "floating" investigations and precise surveys after "floating" repairs, ensuring that there are no discrepancies in results regardless of who conducts the inspection. Using a method called "V-transmission," we propagate ultrasonic waves into the structure and detect delaminations (voids) within the structure from the waveforms of the reflected ultrasonic waves. Since ultrasonic waves can be transmitted and propagated through the air, there is no need for a contact medium. 【Features】 ■ Inspection results can be saved as data ■ No differences due to human perception ■ Ultrasonic waves can be transmitted and propagated through the air ■ No need for a contact medium *For more details, please refer to the PDF document or feel free to contact us.

Introduction of various surveys and proposals using infrared cameras, radar rebar detection, and various tests.

At Sanxin Building Materials Industry Co., Ltd., we conduct surveys that include thermal images of exterior walls as visual aids for exterior wall inspections. By using infrared images in addition to traditional surveys, we can visually appeal to clients, leading to a deeper understanding. Additionally, for inspections of concrete structures, we utilize the radar rebar detector "SIR-EZ," which combines a control computer and exploration device into one, allowing for quick detection of rebar and non-metallic pipes within the structure. A laser pointer is used to indicate the location of the area currently being surveyed and the position of embedded objects such as rebar from the front and side of the exploration device. We provide a speedy rebar survey without careless mistakes. 【Features】 ■ Ability to visually appeal using infrared images ■ Quick detection of rebar and non-metallic pipes within concrete structures ■ Significant improvement in work efficiency by using a device equipped with a laser pointer ■ Various surveys including core sampling, compressive strength testing, carbonation testing, and report preparation *For more details, please refer to the PDF document or feel free to contact us.

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
