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. The manufacturing method of the 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 combines the uneven parts of two components and joins them together. This structurally enhances strength and achieves even higher load-bearing performance. It also exhibits high durability against "twisting" loads caused by "vehicle tires," which has been a weakness of conventional products. 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 due to loads from "vehicle tires" causing it to become "damaged in a scattered state." This product addresses such issues through the new manufacturing method. *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.

Okagreat Co., Ltd.'s "Safety Walker G·D" and "Safety Walker L·D" are "evolutionary 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 the surface material structure, making them useful in various scenarios. These 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 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 resistant to breakage. They are also ideal for preventing grating damage. Additionally, the structure makes it difficult for stones and debris to clog the grating itself, preserving the aesthetic. Multiple slit holes are made in the surface material of "striped steel plates" or "patterned steel plates" to balance drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of conventional types. When passing through areas near entrances and exits, where grating frequently breaks, the difference becomes very apparent, especially when using golf carts. You will be able to experience the difference compared to conventional grating.

We would like to introduce the "U-shaped gutter grating" with a "steel zinc-coated finish" handled by Okagreat Co., Ltd. The "U-shaped gutter grating" with a "steel zinc-coated finish" is a standard product that allows for easy covering by simply installing a grating with a two-sided flange onto concrete secondary products such as "U-shaped gutters" and "bench flumes." The steel material used is "SS400." The balance of "strength" and "ductility" in the steel (iron) itself is a characteristic of "SS400." It is neither too hard nor too soft. If it is too hard, cracks may form at the welded joints, and if it is too soft, it may not meet the required load capacity. This product effectively utilizes the advantages of "SS400" in its grating. The surface treatment is a "hot-dip galvanized" finish, which enhances corrosion resistance and allows for long-term use. The specifications of the grating include "standard mesh" and "fine mesh," allowing you to choose according to your application. Additionally, the top surface is designed with a "non-slip" pattern to enhance slip resistance. As an option, processing such as "bevel cutting," "end dimensioning," and "notching" can also be performed. By connecting the U-shaped gutter grating with connection clips, it is also possible to prevent theft and bouncing.
