SDGs Grating! Let's keep rivers and oceans clean! 'Screen Grating'

SDGs Grating! Let's keep rivers and oceans clean! 'Screen Grating'

Catch the garbage! Don't pollute the sea or rivers! Grating with a screen, "Screen Grating."

We would like to introduce the "Screen Grating" handled by Okagreat Co., Ltd. We have been hearing more news about ocean pollution caused by plastic waste. Various industries are making efforts to reduce plastic waste, such as charging for plastic bags and switching to paper straws. 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 ditch to prevent debris from flowing into 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 ditches for concrete secondary products and for longitudinal raised grating, among others. (The main image shows the "U-shaped ditch type.") We offer options for U-180, U-240, U-300, and other special or custom dimensions for concrete secondary products, so please feel free to consult with us. If you have any inquiries, please do not hesitate to contact us.

"L-shaped rubber" α for soundproofing, noise reduction, and preventing rattling of U-shaped gutter grates.

"L-shaped rubber" for noise prevention, soundproofing, and vibration reduction of U-shaped gutters! Comes with double-sided tape. The structure. The U-shaped gutter. The joints. The steps.

We would like to introduce the noise prevention 'L-shaped rubber' for U-shaped channel grating handled by Okagreat Co., Ltd. We often hear about the issue of U-shaped channel grating rattling, making noises like "clack, clack" and "rattle, rattle," and the desire to address these rattling sounds. By simply applying this 'L-shaped rubber,' you can reduce the unpleasant rattling noise. (If the rattling noise does not subside even after applying the L-shaped rubber, other issues may need to be considered.) To accommodate the sizes of the flange part (end angle) of U-shaped channel grating, we offer three sizes: large, medium, and small. This 'L-shaped rubber' can be applied to U-shaped channel grating (with two flanges) for concrete secondary products such as U-150, U-180, U-240, U-300, U-360, U-400, U-450, U-600, and for special channel widths in site-cast side ditches. Please feel free to consult us when you need our services.

Grating "Safety Walker G·D" (Grip Design)

Grating "Safety Walker G·D" (Grip Design)

Evolutionary grating. An evolved form that sublimates into the components of industrial design. With excellent safety and design, it blends into the urban landscape smartly.

The "Safety Walker G·D" U-shaped gutter type is not only suitable as a grating for on-site casting, but also for various types of drop-in and bolt-fixed covers, raised types, and other special dimensions. (For concrete precast products, please feel free to consult us.) Due to its structural design, the top surface has a rugged material structure, making it resistant to twisting and impacts from vehicle tires, which prevents the grating from breaking easily and is ideal for damage prevention. Additionally, the design minimizes the likelihood of stones and debris getting trapped in the grating, preserving the aesthetic appearance. The top surface features a special steel plate ribbed with a rugged pattern, with multiple slit holes to balance drainage and strength. It has also been reported that its slip resistance exceeds that of conventional types. *For more details, please refer to the PDF materials or feel free to contact us.
