Side Ditch Comprehensive Catalog Additional Publication

Achieving economy, strength, and durability, the two-row drainage channel and slit holes capture rainwater!

The "Win Side Ditch" is a new free-gradient side ditch that combines economic efficiency with strength and durability as a product. It features two rows (double) of drainage channels and slit holes arranged in the main beam and cover, effectively capturing rainwater. Thanks to its super drainage capacity, a collection grating is unnecessary. The slit holes are flared, making them less prone to clogging. 【Features】 ■ Two rows of drainage channels and slit holes effectively capture rainwater ■ Suppresses road surface subsidence ・ The side walls have a flat shape without irregularities ■ Lightweight cover significantly reduces construction costs ・ Excellent drainage function minimizes the need for grating ■ Prevents water accumulation on roads and rainwater runoff to residential areas *The sales area is limited to the Kinki region (2 prefectures and 4 counties) and the Kanto region.

It has a double safety structure to prevent the lid from popping up and scattering.

The FD drain, which serves as a curb and drainage channel for bridges, features a double safety structure that prevents the cover from bouncing up and scattering. The underlying SG (melted zinc-aluminum alloy) coating has several times the corrosion resistance of standard hot-dip galvanized coatings, providing excellent rust prevention. Additionally, it has superior adhesion to various types of paint, ensuring that there is no concern about peeling over time. The nylon 12 coating maintains an average thickness of over 300μm, effectively blocking moisture from the iron substrate and underlying coating, thus achieving a long lifespan. Its excellent wear resistance means that even in harsh environments like road shoulders, it is less likely to chip or peel. For more details, please contact us or refer to the catalog.

We are pleased to announce that starting from October 20, 2025, we will be adding new features, "Message Sending Function" and "IoT Integration Function," to our health management solution "GenVital LTE." "GenVital LTE" is a service that assesses the physical condition of on-site workers in four levels based on heart rate and location data collected from wristbands, as well as the heat index at the work site, and sends alert notifications to both the work manager and the workers themselves. With the addition of these new features, work managers will be able to send predefined or custom messages to the wristbands, allowing the wearers to receive notifications through sound and vibration, enabling quick and efficient work instructions and alerts. Additionally, by integrating with the cloud measurement service provided by GRIFFY, automatic notifications will be sent to the wearers when measurement values such as rainfall, wind speed, slope, noise/vibration, and dust concentration exceed warning levels. This will achieve complete automation of the work process, from data measurement to alerting on-site workers. This will further contribute to improving the safety of on-site workers and streamlining and reducing labor in site management.
