New product NEXCO certified | CF-20 | NCF type | 3LII-150 | 3LII-160 |

To adopt our products on the expressway (NEXCO), it is necessary to obtain certification in accordance with NEXCO's guidelines. Our lineup for NEXCO has traditionally included the CF type (expansion amounts of 30, 50, and 80mm) and the 3LII type (expansion amounts of 200, 250, 300, and 350mm). However, there was a gap between 80mm and 200mm, making it difficult to provide good proposals for projects requiring an expansion amount of 100mm. To address this demand, we developed the NCF-100 with an expansion amount of 100mm, and the 3LII-150 and 3LII-160 with expansion amounts of 150mm and 160mm, respectively. Additionally, we developed the CF-20 with a compact design and an expansion amount of 20mm, as well as the NCF type that can handle snow compaction. We are pleased to announce that these new products have received new certification from NEXCO. It is worth noting that the expansion amounts of 150mm and 160mm are close because the order documents may specify those exact expansion amounts. Please feel free to request materials or contact us at the timing of your product consideration before bidding or after winning the bid.

Proven durability of 50 or 100 years through fatigue load testing!

The Hybrid Joint NS-LL type and 3LIIA type have been tested under the fatigue durability test specified by NEXCO, confirming a durability of 50 years after 6 million load cycles. Furthermore, the 3LIIA type will undergo another fatigue loading test in November 2024. After 12 million load cycles, a durability of 100 years has been confirmed! This proves its ultra-long-term durability. Traditionally, expansion joints are often required to have a durability of around 30 years, but bridges are expected to last 100 years, so it is undeniable that expansion joints can shorten the lifespan of bridges. Our product, the Hybrid Joint, contributes to extending the lifespan of the expansion joint 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. 【NS-LL Type Features】 ○ 50 years of durability and water-tightness ○ Ultra-low noise and low vibration ○ Steel vertical shape 【3LIIA Type Features】 ○ 100 years of durability ○ 50 years of water-tightness ○ Large expansion amount and wide gap For more details, please contact us or request a catalog.

• Foundation construction

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.
