Our company manufactures the "U-shaped for crossing," which resolves various issues commonly seen in fixed grating side ditches. It requires minimal adjustments on-site and is easy to install, allowing for a reduction in construction time of about one week to ten days. Additionally, we can accommodate changes in the shape of the top edge to match decorative tiles or stone cladding. This reduces unnecessary exposure of the grating and allows for installations that consider aesthetics and design. It has also been adopted in places like the New National Stadium and the Imperial Palace. 【Features】 - Bases can be made to match the angle of the longitudinal slope, allowing for installation without steps even on slopes. - Both standard and fine mesh options can accommodate fractional lengths in 10 cm increments as standard stock. Short lengths are also available. - Products with slopes for transverse gradients (some stock available; orders can also be accepted). - There are dedicated drainage pits that can be installed with the same width as the side ditch (intermediate pits and final pits). *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

This is a block that integrates the pedestrian walkway and apron. It features a mount-up and semi-flat design, and since it is a single unit, there is no displacement or tipping at the curb area. It can be restored without any on-site pouring, and by applying a slip-resistant finish called "No Skid Finish" to the surface, it reduces slip accidents for people, bicycles, and motorcycles. The small protrusions of the "No Skid Finish" help to reduce falling accidents, decrease vehicle reflection in rainy weather, provide a comfortable walking experience, and enable quick drainage of surface rainwater.
