オカグレート List of Products and Services

The "OG Lock Pit" is a product that does not require post-installed anchors for concrete products and features a fixing method that does not protrude any objects from the surface of the lid. By simply tightening the OG lock bolts at two points, it can be securely fixed and closely adhered to the side ditch. Unlike anchor installations, there are no bolts or nuts protruding from the surface of the lid, which does not obstruct pedestrian traffic. Additionally, it can also be used as a pit lid for cable and wiring in solar power plants, mega-solar installations, and solar farms. 【Features】 ■ No anchor installation required ■ Securely fixed to the side ditch by tightening OG lock bolts at two points ■ Does not obstruct pedestrian traffic ■ Effective in preventing rattling noise *For more details, please refer to the PDF document or feel free to contact us.

• Security devices

Okagreat Co., Ltd.'s "Safety Walker G·D" and "Safety Walker L·D" are designed to be less prone to clogging from small stones and debris compared to traditional grating. They also suppress the accumulation of fallen leaves and maintain hygiene, while offering an attractive appearance and a robust surface material structure that makes them resistant to damage, making them an "evolved grating." These gratings are suitable not only for on-site casting but also for various types of drop-in and bolt-fixed installations, 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 a material structure that is strong against twisting and impacts from vehicle tires, making the grating very durable and ideal for preventing damage. Additionally, the design minimizes the likelihood of stones and debris clogging the grating itself, preserving the visual appeal. Multiple slit holes are incorporated into the surface's "striped steel plate" or "patterned steel plate" to balance drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of traditional models. You can truly experience the differences compared to conventional grating, such as "leaves falling into the gutter making cleaning difficult" or "frequent damage to the grating near entrances."

• Other power generation

We would like to introduce the "Screen Grating" handled by Okagreat Co., Ltd. We have been hearing more 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 grating and debris screens, 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 photos show the "U-shaped channel type" and the "JIS drainage channel type.") Please feel free to consult us regarding U-180, U-240, U-300, and other special or custom dimensions, as well as those for concrete secondary products. If you have any inquiries, please do not hesitate to contact us.

• Gates, walls and fences

We would like to introduce the new model of OG Super High Tensile High Strength Stainless Steel Fine Grating, 'Fine Grate (Fine Pitch 15)' (U-shaped drain type), handled by Okagreat Co., Ltd. Awarded the 2024 Good Design Award. The manufacturing method of OG Super High Tensile High Strength Stainless Steel Grating has been improved! It exhibits high durability performance against loads in the "twisting" direction! The new model combines the uneven parts of two components and joins them together. This structurally enhances strength and achieves even higher load-bearing performance. It also demonstrates high durability performance against "twisting" loads caused by "vehicle tires," which was a weakness of conventional products. The "R" shape of the flange quickly directs rainwater into the side ditch, improving drainage performance. Some of you may have experienced stainless steel grating failing and becoming "disassembled" due to loads from "vehicle tires" and "twisting." This product addresses such issues through a new manufacturing method. *For more details, please refer to the PDF document or feel free to contact us.
