The surface rubber, receiving plate, and receiving base have a separated structure, so wear of the surface rubber does not expose the steel plate that causes slipping, allowing for safe operation!
The "K-80" is a diamond-free joint developed by our company based on extensive experience for horizontal joints. By adopting a high-nut type anchor bolt, it eliminates the need to chip concrete during repairs, resulting in no noise or debris waste, and it can also shorten construction time. Additionally, the reduction in time helps minimize exhaust emissions caused by traffic congestion, thus preserving the living and working environment in urban areas and the natural environment in suburban areas. 【Features】 ■ Protects the floor slab ■ Comfortable driving ■ Safe driving ■ Environmentally friendly ■ Cost-saving *For more details, please download the PDF or feel free to contact us.
