We would like to introduce the FRP series "FRP Checker Plate" handled by Okagreat Co., Ltd. The "FRP Checker Plate" is a board made of FRP with a checkered steel plate pattern, featuring excellent properties such as lightweight, high strength, corrosion resistance, weather resistance, and insulation. It can be used for various applications including flooring and wall materials. FRP stands for "Fiber Reinforced Plastic," which is plastic reinforced with glass fibers. Due to the characteristics of FRP, it is used as parts and materials in various fields such as ships, vehicles, aviation, and construction. By forming FRP into a "checker plate" shape (a board with a checkered steel plate pattern), it can be used for a wide range of applications. The board thicknesses are 6.0 mm, 10.0 mm, 15.0 mm, and 20.0 mm (single plate type). Additionally, we can also produce "composite plate types" that are formed with urethane in a sandwich structure or with honeycomb materials sandwiched in (total thickness ranges from 33 mm and above). *For more details, please refer to the PDF materials or feel free to contact us.

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 structure that makes them resistant to damage, making them an "evolved type of 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-sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the top surface is made of a panel structure, making them strong against twisting and impacts from vehicle tires, which significantly reduces the likelihood of grating damage. They are also ideal for preventing grating damage. Moreover, the design minimizes the accumulation of stones and debris on the grating itself, preserving the aesthetic appeal. The top surface features multiple slit holes in "striped steel plates" or "patterned steel plates," balancing drainage and strength. Additionally, it has been reported that the slip resistance exceeds that of traditional types. You can truly experience the difference from conventional grating, such as frequent damage near entrances or the difficulty of cleaning due to fallen leaves accumulating in the gutters.

Furthermore, it has been reported that the slip resistance exceeds that of conventional types. You will likely notice that the grating frequently breaks near entrances and exits, which is a significant difference from conventional grating. *For more details, please refer to the PDF materials or feel free to contact us.

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, keeping them 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. They 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 precast products, etc.). Due to their structural design, the surface is made of material 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 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 surpasses that of conventional types. If grating frequently breaks near entrances and exits, the difference becomes apparent when passing through with a golf cart or similar vehicle. It is clear that it is different from conventional grating.

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, making it useful in various scenes. It can be used not only as grating for on-site casting 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 its structure, the surface is made of material, making it strong against twisting and impacts from vehicle tires, ensuring that the grating is difficult to break. It is also ideal for preventing grating damage. Additionally, due to its structure, the grating itself is less likely to get clogged with stones or debris, preserving the landscape. The surface features multiple slit holes in the "striped steel plate" or "patterned steel plate," balancing drainage and strength. Furthermore, the "anti-slip effect" has been reported to exceed that of conventional types. Wheels of carts getting caught and making it difficult to pass... Grating frequently breaking near entrances... The differences are quite clear. It feels different from conventional grating.

We would like to introduce the "OG Super High Tensile High Strength Stainless Steel Grating New Model" handled by Okagreat Co., Ltd., specifically the 'Fine Grate (Fine Pitch 15)' (U-shaped drain type). The manufacturing method of the OG Super High Tensile High Strength Stainless Steel Grating has been improved! It exhibits high durability performance even under torsional loads! The new model combines the uneven parts of two components for a stronger structural integrity, achieving even higher load-bearing performance. It also demonstrates high durability performance against torsional loads caused by "vehicle tires," which was a weakness of conventional products. Additionally, the "R" shape of the flange quickly directs rainwater into the side ditch, enhancing drainage performance. Please feel free to consult with us when you need our products.
