We would like to introduce the "Safety Walker - Liner Design Square Manhole Cover Type" handled by Okagreat Co., Ltd.

(Please feel free to consult us for concrete precast products, etc.) Due to its structural design, the top surface is made of a panel structure, making it resistant to twisting and impact from vehicle tires, thus preventing the grating from breaking easily and making it ideal for damage prevention. Additionally, the structure minimizes the likelihood of stones and debris getting caught in the grating, preserving the aesthetic appearance. Multiple slit holes are made in the special steel plate "patterned steel plate" on the top surface, balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of conventional types. *For more details, please refer to the PDF document or feel free to contact us. 【Features】 ■ Safety (difficult to break due to panel structure) ■ Reliability (less slippery due to patterned steel plate) ■ Strength (up to maximum T-25 load) ■ Lightweight (lighter than fine types) ■ Aesthetics (prevention of clogging) ■ Damage prevention (distributes force over a surface)
