In repairs that do not require chipping, you can prolong the lifespan of the bridge without damaging the deck and reduce maintenance costs!
The "K-210" is a diamond-free joint suitable for horizontal joints, designed to accommodate bridge structures with wide spans that consider displacements during earthquakes, and is ideal for repairs of finger joints. Since the surface rubber, receiving plate, and support structure are separated, wear of the surface rubber does not expose the steel plate that can cause slipping, allowing for safe travel. Additionally, the surface rubber has sufficient thickness, and the receiving plate that supports the load is coated with rubber on the steel plate, which helps to mitigate impact loads and reduces the effects on the deck slab. 【Features】 ■ Protects the deck slab ■ Comfortable travel ■ Safe travel ■ Environmentally friendly ■ Cost-effective *For more details, please download the PDF or feel free to contact us.
