Water-through overflow prevention grating! High rainwater absorption performance!

Water-through overflow prevention grating! High rainwater absorption performance!

A new form of grating for flood control measures. Improved rainwater absorption performance with a slider plate!

We would like to introduce "Water Through," which is handled by Okagreat Co., Ltd. "Water Through" is a product that not only improves drainage capacity but also combines ease of maintenance and enhanced safety during use. By maintaining a distance of over 100 meters to the first auxiliary component on the upstream side of the main body and providing a slider plate on the upstream side of the receiving frame, the flow of rainwater is stabilized. It demonstrates its effectiveness during significant rainfall events such as recent typhoons, heavy rains, and linear precipitation zones. This overflow prevention grating enhances rainwater absorption performance and increases drainage capacity. It has become possible to capture a large volume of water, which has increased in force, through the slider plate into the drainage channel. 【Features】 - Prevents the cover from floating up by combining the cover body and the receiving frame. - The gaps that may occur after installation are covered by the slider plate, promoting smooth drainage. - The receiving frame, cover, and road surface are nearly flat, eliminating tripping hazards for pedestrians and impacts on vehicles. *For more details, please refer to the PDF materials or feel free to contact us.

Next-generation non-slip, high-grip grating 'S-HG'

Fine molten particles are closely adhered, providing an enormous anti-slip effect in various directions! A stainless steel grating that exhibits an unprecedented non-slip effect!

"S-HG" is a stainless steel grating that exhibits excellent grip functionality due to advanced coating technology. By evenly densifying fine molten particles (thermal spraying), we have successfully enhanced the non-slip effect of the main grating component. Additionally, the non-slip surface is free of bumps and edges (angles), minimizing the risk of abrasions during falls. 【Features】 ■ High non-slip effect ■ Excellent strength and durability due to thermal spraying technology ■ Gentle design philosophy prioritizing safety ■ Beautiful form considerate of stainless steel material *For more details, please refer to the PDF document or feel free to contact us.

OG Super High-Tension High-Strength Stainless Steel Grating - New Model!!

OG Super High-Tension High-Strength Stainless Steel Grating - New Model!!

OG Super High-Tensile High-Strength Stainless Steel Grating New Model! Exhibits high durability performance even under loads in the "twisting" direction!

We would like to introduce the "OG Super High Tensile High Strength Stainless Steel Grating New Model" and "U-shaped Drainage Type" handled by Okagreat Co., Ltd. We have improved the manufacturing method of the OG Super High Tensile High Strength Stainless Steel Grating! It demonstrates high durability against loads in the "twisting" direction! The new model features a combination of the uneven parts of two components that are joined together. This structurally enhances strength and achieves even higher load-bearing performance. It also exhibits high durability against "twisting" loads caused by "vehicle tires," which has been a weakness of conventional products. Additionally, the "R" shape of the flange allows rainwater to be quickly directed into the side ditch, improving drainage performance. Please feel free to consult with us when you need assistance.

Safety walker installed at a golf course of a major company in the Tokyo Stock Exchange Prime market.

Safety walker installed at a golf course of a major company in the Tokyo Stock Exchange Prime market.

Safety walker installed at a major company golf course in the Tokyo Stock Exchange Prime market. Its structure makes it difficult to clog, resistant to breakage, and lightweight. It has a nice flat feel.

The "Safety Walker G・D" and "Safety Walker L・D" are an evolved type of grating that, compared to conventional grating, is less prone to clogging from small stones and debris, always maintaining hygiene, has an appealing appearance, and is resistant to damage due to its surface material structure. This makes it useful in various scenarios. In addition to being suitable for site-cast gratings, it can also be used for various types of drop-in and bolt-fixed gratings, raised types, and other special dimension covers (please consult us for concrete precast products, etc.). Due to its structural design, the surface is made of a material structure that is strong against twisting and impacts from vehicle tires, making it difficult for the grating to break. It is also ideal for preventing grating damage. Moreover, its design minimizes the accumulation of stones and debris on the grating itself, preserving the aesthetic appeal. Multiple slit holes are made in the surface material of "striped steel plates" or "patterned steel plates," balancing drainage and strength. Additionally, it has been reported that its slip resistance exceeds that of conventional types. When grating frequently breaks near entrances and exits, the difference is noticeable when passing through with golf carts, for example. It is clear that it is different from conventional grating.
