~ "Manufacturing that saves lives" as a concept for development ~ Witnessing the Great East Japan Earthquake, we wondered what we could do as a concrete company. What we arrived at was the "Photoluminescent Sign Plate." This product uses a high-brightness photoluminescent material that accumulates sunlight and emits light for a long time in the dark, serving as a final guide during "lifeline disconnection." With the use of special materials, it boasts high durability and water resistance, making it suitable for outdoor use. 【Features】 ■ Can be installed not only on grates but also on ductile covers (cast iron products) ■ Can be directly installed on road surfaces ■ Residual brightness of over 3 mcd/m2 after 12 hours of sunset ■ Long-term outdoor compatibility ■ Utility model registration No. 3202965 ■ Trademark registration No. 5862708 *For more details, please download the PDF or feel free to contact us.
