For use with on-site poured catch basins. Additionally, for bolt-fixed manhole covers, manhole covers and sumps with special dimensions, and various types of basins.
We would like to introduce the "Safety Walker Grip Design Square Manhole Cover Type with Bolt Fixing" handled by Okagreat Co., Ltd. The "Grip Design Square Manhole Cover Type with Bolt Fixing" is suitable not only for site-cast drainage manholes but also for various types of bolt-fixed manhole covers, sump covers, and specially sized square covers. (Please feel free to consult us for concrete precast products and more.) Due to its structural design, the top surface is made of a panel structure, making it resistant to twisting and impacts from vehicle tires, thus preventing damage to the grating. Additionally, the design minimizes the likelihood of stones and debris getting stuck in the grating, preserving the aesthetic appearance. Multiple slit holes are made in the special steel plate "ribbed steel plate" on the top surface, balancing drainage capability and strength. It has also been reported that the anti-slip effect exceeds that of conventional types. The bolt-fixing design also helps prevent theft. 【Features】 ■ Safety (difficult to break due to panel structure) ■ Reliability (non-slip due to patterned steel plate) ■ Strength (up to maximum T-25 load) ■ Lightweight (lighter than fine types) ■ Aesthetic (prevents clogging) ■ Damage prevention (distributes force over a surface) *For more details, please refer to the PDF document or feel free to contact us.
