Notice of specification changes and expansion of application conditions for "Hybrid Joint LL Type"

Confirmed durability of 50 years through fatigue endurance testing!

The Hybrid Joint NS-LL type and 3LIIA type have been confirmed to have a durability of 50 years after undergoing a loading test of 6 million cycles as specified by NEXCO's fatigue durability test. Traditionally, expansion devices are often required to have a durability of about 30 years, but since bridges are expected to last 100 years, it is undeniable that expansion devices can shorten the lifespan of bridges. Our product, the Hybrid Joint, contributes to extending the lifespan of the expansion device itself, thereby reducing lifecycle costs and promoting the longevity of bridges. We offer a wide range of products from small to large, accommodating expansion amounts from 20mm to 600mm. 【Features】 ○ 50 years of durability ○ High water-tightness ○ Steel vertical shape ~~ We are currently seeking agents! Agents from the Tohoku and Hokuriku regions are very welcome! Of course, we can also accommodate companies from other regions! ~~ For more details, please contact us or request a catalog.

The adhesion between the steel plate and rubber was confirmed to have no delamination in the tensile test!

The Hybrid Joint NS-LL type is manufactured using the press vulcanization bonding technology, which is also used in the production of bearings. Regarding the bonding part, it has been confirmed through a tensile test by the Chemical Substance Evaluation Research Organization that the failure mode was material failure rather than cohesive failure, meaning there was no delamination. This indicates that the steel plate and rubber are bonded very strongly, making it a product with excellent water-tightness. In addition to the strong adhesive force between the rubber and the steel plate, the structure is designed so that the water-stopping rubber does not come into direct contact with the tires of passing vehicles, making it less prone to wear. The range of products available includes both small and large items, accommodating expansion amounts from 20mm to 175mm and a maximum applicable slab gap of 395mm. **Features** - High water-tightness - Steel vertical tooth shape - One-lane assembly product ~~ We are currently seeking agents! Agents from the Tohoku and Hokuriku regions are very welcome! Of course, we also accommodate companies from other regions! ~~ For more details, please contact us or request a catalog.

By installing the guide board, it prevents damage to the main body by the grader in snowy areas.

The hybrid joint is a non-drainage expansion device developed using a composite technology of rubber and steel materials, achieving very high water-tightness by press vulcanizing and bonding steel plates and rubber. Furthermore, by adopting a steel vertical shape for the load-bearing structure, the surface exposure area has been minimized, improving sound insulation and durability. The range of products available includes both small and large items, accommodating expansion amounts from 20mm to 175mm, and a maximum applicable slab gap of 395mm. 【Features】 ○ High water-tightness ○ Steel vertical tooth shape ○ One-lane assembly product ~~ Currently seeking agents; agents from the Tohoku and Hokuriku regions are very welcome!

[NETIS Registered Product] A bridge expansion device with high water stop performance, comfortable driving, and ultra-low noise.

This is a bridge expansion device adopted nationwide, primarily by the Ministry of Land, Infrastructure, Transport and Tourism, NEXCO, urban expressways, local governments, and other public organizations. 【Features (excerpt)】 ◆ Compatible with small to large bridges Handles expansion amounts from 20mm to 600mm, with a maximum gap of 1230mm. Other specifications can be designed separately. ◆ Usable for all types of bridges Can be used for all types of bridges, including steel bridges, PC bridges, RC bridges, as well as arch bridges and curved bridges. ◆ High water-tightness "NS-LL type": The steel plate and sealing rubber are bonded using a mold (press vulcanization bonding), preventing separation between the steel plate and rubber. ◆ Safe and easy installation Can be installed using a 4-ton unic crane without the need for large machinery like medium to large rough terrain cranes, allowing for safe and easy (speed-up) construction. Here’s a brief introduction to some installation examples! ~~ At the Tochigi Prefecture Nikko Civil Engineering Office (Maruyama Bridge), a "Hybrid Joint" was used for renovation work. * NS-LL type repair ~~ At the Kinki Regional Development Bureau Kinokawa River National Road Office (Takasegawa Bridge), it was used for a newly constructed bridge. * 3L type For more details, please contact us or download the catalog.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

The comprehensive production management system "TED Ver.3.0," developed and sold by Profect Co., Ltd., has received the "Excellence Award" in the Software category at the "38th Small and Medium Enterprises Excellent New Technology and New Product Award," co-sponsored by the Resona Foundation for Small and Medium Enterprise Promotion and Nikkan Kogyo Shimbun (announced in the April 15, 2026 edition of Nikkan Kogyo Shimbun). This award is a prestigious recognition that honors outstanding new technologies and products, supported by the Ministry of Economy, Trade and Industry's Small and Medium Enterprise Agency and the Organization for Small & Medium Enterprises and Regional Innovation. ■ Message from President Shiro Abe This system was developed with the participation of eight small manufacturing companies from across the country as "stakeholders," and it was created by thoroughly examining whether it can truly be used on-site and whether it can lead to profits, rather than being just theoretical. We believe that in DX (digital transformation), what is important is "who to work with." Moving forward, we will continue to enhance our functions and support for implementation, and we will strive to create new value together with everyone under the banner of "restoring manufacturing."
