We have renewed our homepage. A variety of the latest grating products are now featured. (Okagrate Co., Ltd.)

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

The "Safety Walker G・D" and "Safety Walker L・D" are advanced grating systems that are less prone to clogging from small stones and debris compared to traditional grating, ensuring they remain hygienic at all times. They also have an appealing appearance and are less likely to break 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 such as drop-in, bolt-fixed, raised types, and other specially sized 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 accumulation of stones and debris on the grating itself, preserving the aesthetic appeal. Multiple slit holes are created in the "striped steel plate" or "patterned steel plate" on the surface, balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of traditional models. If you frequently experience damage to grating near entrances and exits, you will likely realize that this is different from conventional grating.

The new model of OG Super High Tensile High Strength Stainless Steel Grating, "Fine Great"! It demonstrates high durability performance even under loads in the "twisting" direction!!

We would like to introduce the new model of OG Super High Tensile High Strength Stainless Steel Grating, 'Fine Grate (Fine Pitch 15)' (U-shaped drain type), handled by Okagreat Co., Ltd. The manufacturing method of OG Super High Tensile High Strength Stainless Steel Grating has been improved! 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 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, enhancing drainage performance. Some of you may have experienced stainless steel grating failing in a "scattered state" due to loads from "vehicle tires" and "twisting." This product has been improved through a new manufacturing method to address such issues. *For more details, please refer to the PDF document or feel free to contact us. If you have any inquiries, please do not hesitate to consult with us.

"Safety Walker" installed at golf courses of companies listed on the Tokyo Stock Exchange Prime. It is designed to be resistant to clogging, durable, and lightweight. It has a good flat feel.

Okagreat Co., Ltd.'s "Safety Walker G·D" and "Safety Walker L·D" are "evolved grating" products that are less prone to clogging from small stones and debris compared to conventional grating, ensuring they remain hygienic at all times. They also have an appealing appearance and are less likely to break due to their surface material structure, making them useful in various scenarios. These products can be used not only as site-cast grating but also for various types of drop-in and bolt-fixed grating, raised types, and other special-sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface is made of a material structure that is resistant to twisting and impact from vehicle tires, making the grating particularly durable and ideal for preventing damage. Additionally, the design minimizes the likelihood of stones and debris clogging the grating itself, preserving the aesthetic appeal. Multiple slit holes are incorporated into the "striped steel plate" or "patterned steel plate" on the surface to balance drainage and strength. It has also been reported that the slip resistance exceeds that of conventional types. If grating frequently breaks near entrances and exits, the difference is easily noticeable when passing through with a golf cart or similar vehicle. You will truly feel that it is different from conventional grating.
