オカグレート List of Products and Services

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 traditional grating, ensuring they remain hygienic at all times. They also have an attractive appearance and are less likely to break due to their surface material structure, making them useful in various scenarios. In addition to being used as site-cast grating, they can also be utilized in various types of recessed and bolt-fixed grating, 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 resistant to twisting and impact from vehicle tires, making the grating very durable and ideal for preventing damage. Moreover, the design minimizes the accumulation of stones and debris in the grating itself, preserving the aesthetic appeal. Multiple slit holes are incorporated into the "striped steel plate" or "patterned steel plate" on the surface, balancing drainage and strength. Additionally, it has been reported that the slip resistance exceeds that of traditional types. You can clearly notice the difference when passing through areas where grating frequently breaks, such as near entrances, especially when using golf carts. You will experience the distinction from traditional grating firsthand.

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 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 structure, the surface is made of material, making them strong against twisting and impacts from vehicle tires, making them difficult to break. They are also ideal for preventing grating damage. Additionally, because of their structure, the gratings themselves are less likely to get clogged with stones and debris, preserving the landscape. Multiple slit holes are made in the "striped steel plate" or "patterned steel plate" on the surface to balance drainage and strength. Furthermore, the "anti-slip effect" has been reported to exceed that of conventional types. If you have issues such as cart wheels getting caught and making it difficult to pass, or frequent grating damage near entrances, please consider these products. *For more details, please refer to the PDF materials or feel free to contact us.
