Thermal sprayed coating is applied on the uneven portion. The convex portion is coated with ceramics, thus it has high anti-slipping features. We have more than 20 colors. By combining different colors, it is possible to design your own unique color scheme. Please choose suitable ones from 20 colors depending on your taste. |

 Safety of pedestrian first
Manhole lids with resin coating tend to be slippy, and become much slippier when the surface coating peels off. By the ceramic coating, the surface of color manhole lids has proper roughness which resists slipping. Therefore, it has high anti-slipping features, which is kept long because of high abrasion-resistance nature of ceramics. Superior anti-corrosion features compared to resin coating
Until now, manhole lids have been coated with resin materials.
However there has been a problem that its initial beauty cannot be kept for a long time because of fast wear-off and pale-off due to severe conditions on roads. A new material, ceramics, can overcome these shortcomings. Ceramics enabled longer life of manhole lids where high degree of anti-abrasiveness is required. |
