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

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.

Clean oceans and rivers SDGs 'Screening Grating' catches garbage.

Clean oceans and rivers SDGs 'Screening Grating' catches garbage.

Catch the trash! A grating with a screen for catching garbage, the "Screen Grating," to prevent pollution in oceans and rivers!

We would like to introduce the "Screen Grating" handled by Okagreat Co., Ltd. We have been hearing a lot about marine pollution caused by plastic waste. With the introduction of paid plastic bags and the shift to paper straws in various industries, efforts are being made to reduce plastic waste. This "Screen Grating" integrates the grating and the debris screen, which were traditionally installed separately, achieving significant cost savings. It is installed at the edge of the drainage channel to prevent debris from entering the interior, and when the screen is not in use, it can be easily stored in the grating body with a one-touch mechanism. Removing accumulated debris is also simple. It is suitable for U-shaped channels for concrete secondary products and for raised grating for longitudinal use, among others. (The main image shows the "U-shaped channel type," and the sub-image shows the JIS drainage channel type.) Please feel free to consult us regarding U-180, U-240, U-300, and other special or custom dimensions for concrete secondary products. If you have any inquiries, please do not hesitate to contact us.

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.

Safety Walker β installed at a famous ramen shop as a measure against large vehicle entrance and exit issues.

A safety walker installed at a famous ramen shop as a measure against large vehicle entrance and exit. It is durable, structurally resistant to clogging, and lightweight. The flatness feels good.

The "Safety Walker G・D" and "Safety Walker L・D" are an evolved type of grating that, compared to conventional grating, is less likely to become clogged with small stones and debris, maintaining hygiene at all times. They also have an attractive appearance and are less prone to damage due to their surface material structure, making them useful in various scenarios. They can be used not only as grating for on-site casting but also for various types of drop-in and bolt-fixed grating, raised types, and other specially sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface material structure makes them strong against twisting and impacts from vehicle tires, making it difficult for the grating to break. They are also ideal for preventing grating damage. Additionally, the design prevents stones and debris from clogging the grating itself, preserving the landscape. The surface features multiple slit holes in the "striped steel plate" or "patterned steel plate," balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of conventional types. You will likely notice that the grating frequently breaks near entrances and exits, which is a significant difference from conventional grating. *For more details, please refer to the PDF materials or feel free to contact us.

Introducing the evolved grating "Safety Walker."

Introducing the evolved grating "Safety Walker."

A new form that matches the urban landscape. The evolved grating "Safety Walker." It has a structural beauty that is clearly different from conventional gratings.

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 attractive appearance, and is less likely to break due to its surface material structure. They can be useful in various scenarios. They are suitable not only as site-cast gratings but also for various types such as drop-in, bolt-fixed, raised types, and other special dimension covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface is made of material, making them strong against twisting and impacts from vehicle tires, thus making the grating difficult to break. They are also ideal for preventing grating damage. Additionally, because of their structure, the gratings themselves are less likely to become clogged with stones or debris, preserving the landscape. The surface features multiple slits in the "striped steel plate" or "patterned steel plate," balancing drainage and strength. Furthermore, the "anti-slip effect" has been reported to exceed that of conventional types. You can clearly see the difference when cart wheels get caught and make it difficult to pass, or when gratings frequently break near entrances and exits. It is evident that they are distinctly different from conventional gratings.
