The new "2024-2025 Comprehensive Catalog" has been released! New grating products included! β

A grating that is less likely to clog due to the suppression of falling debris such as fallen leaves. Installed in the premises of a major company listed on the Tokyo Stock Exchange Prime, the "Safety Walker."

Okagreat Co., Ltd.'s "Safety Walker G·D" and "Safety Walker L·D" are an evolved type of grating that is less prone to clogging from small stones and debris compared to conventional grating. They also suppress the accumulation of fallen leaves and maintain hygiene, have an appealing appearance, and are resistant to damage due to their surface material structure. These gratings can be used not only for on-site installations but also for various types such as drop-in and bolt-fixed styles, raised types, and other special dimensions for 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 them particularly resistant to breakage. They are also ideal for preventing grating damage. Moreover, the design minimizes the likelihood of stones and debris clogging the grating itself, preserving the aesthetic appeal. The surface features multiple slit holes in the "striped steel plate" or "patterned steel plate," balancing drainage capability and strength. Additionally, it has been reported that the slip resistance exceeds that of conventional types. You can experience the difference from traditional gratings, such as frequent breakage near entrances or the difficulty of cleaning due to fallen leaves accumulating in the gutters.

• Other commercial buildings and service facilities

A safety walker installed at a famous ramen shop as a measure for large vehicle entrance and exit. Its structure features a flat top surface, making it durable, resistant to clogging, and lightweight.

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 scenes. They are suitable not only as grating for on-site pouring but also for various types such as drop-in type, bolt-fixed type, raised types, and other special dimension covers (please consult us for concrete secondary products, etc.). Due to their structural design, the surface material structure makes them strong against twisting and impacts from vehicle tires, making them very resistant to breakage. They are also ideal for preventing grating damage. Additionally, the design makes it difficult for stones and debris to clog the grating itself, preserving the landscape. Multiple slit holes are made in the "striped steel plate" or "patterned steel plate" on the surface, balancing drainage and strength. It has also been reported that the anti-slip effect exceeds that of conventional types. If you frequently experience grating damage near entrances and exits, you will realize that these are different from conventional grating. *For more details, please refer to the PDF document or feel free to contact us.

Clean rivers and oceans, gentle on the Earth. A fusion of screens and grates for catching trash. 'Screen Grate'! Preventing waste from flowing downstream.

We would like to introduce the "Screen Grating" handled by Okagreat Co., Ltd. We have been hearing more news about marine 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 drainage channel 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 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, special dimensions, custom sizes, and concrete secondary products. If you have any inquiries, please do not hesitate to contact us.

The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.
