"Hybrid Joint" expansion device confirmed for 50 years of durability.
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.
