Safety walker installed at a golf course of a major company in the Tokyo Stock Exchange Prime market.

Safety walker installed at a golf course of a major company in the Tokyo Stock Exchange Prime market.

Safety walker installed at a major company golf course in the Tokyo Stock Exchange Prime market. Its structure makes it difficult to clog, resistant to breakage, and lightweight. It has a nice flat feel.

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 appealing appearance, and is resistant to damage due to its surface material structure. This makes it useful in various scenarios. In addition to being suitable for site-cast gratings, it can also be used for various types of drop-in and bolt-fixed gratings, raised types, and other special dimension covers (please consult us for concrete precast products, etc.). Due to its structural design, the surface is made of a material structure that is strong against twisting and impacts from vehicle tires, making it difficult for the grating to break. It is also ideal for preventing grating damage. Moreover, its design minimizes the accumulation of stones and debris on the grating itself, preserving the aesthetic appeal. Multiple slit holes are made in the surface material of "striped steel plates" or "patterned steel plates," balancing drainage and strength. Additionally, it has been reported that its slip resistance exceeds that of conventional types. When grating frequently breaks near entrances and exits, the difference is noticeable when passing through with golf carts, for example. It is clear that it is different from conventional grating.
