Product introduction

KFC tooth expansion joint is an expansion joint structure made of FCD material, which is a kind of spherical cast iron with the highest strength among graphite-organized cast iron materials. The KFC expansion joint has a monolithic structure thanks to the complete casting of the joint face plate, the joint support system and the slot anchor bar system in one component without the existence of welds or connection bolts. The monolithic construction of KFC expansion joints provides the characteristic high fatigue strength of this joint compared to other joints.
In addition, the KFC expansion joint is a watertight joint structure with a tight watertight system as well as a dustproof layer made of special long-life materials to prevent rocks and sharp foreign objects from puncture the rubber water-proof rubber layer. The water-resistant properties of the slot are also rigorously tested by the most rigorous tests.

Product features

1. KFC expansion joint features all the features of an expansion joint structure designed and manufactured to conform to Japanese highway standards, including smoothness, soundproof, waterproof, high fatigue strength as well as convenient for maintenance, servicing and replacement.
2. The durability of KFC expansion joints is proven through fatigue testing of 2 million times of applying loads to the joint without breaking or generating residual strain.
   FCD materials have also demonstrated a practical durability life of more than 50 years.
3. With the application of Al-Mg plasma arc metal thermal spray coating on the entire expansion joint, the service life of the expansion joint is significantly increased.Moreover, the metal coating creates a non-slip rough surface for the expansion joint, ensuring the safety of vehicles traveling on the bridge.
