Grated concrete lid
Combine concrete lids and steel grating!
The "Gr Concrete Cover" is a concrete cover designed to reduce the risk of theft of steel grating. By integrating high-value steel grating with concrete covers that would otherwise become industrial waste using L-shaped anchor bars, the risk of theft is significantly decreased. Two Gr Concrete Covers can provide the same drainage capacity as conventional steel grating. Additionally, since they are the same dimensions as existing steel grating, they can be easily replaced to implement theft prevention measures. Our company also offers many other products related to environmental disaster prevention. 【Features】 ■ Theft prevention ■ Excellent drainage performance ■ Easy to replace *For more details, please refer to the PDF materials or feel free to contact us.

A bath cover made of knotless cypress.
A lid for a bath kettle used in a long-established inn in Nara Prefecture.
Currently, we received a request to create a new item because the one in use has become aged. Previously, a young furniture craftsman from another company made a similar lid, but since they only applied the usual "yatoizane" technique, there were no issues when it was freshly made. However, as expected, within a month it warped and cracked, leading to complaints. To prevent such issues, we implemented more complex processing methods like "suitukizan" and "arizanehagi" to create a durable hinoki lid that can be used for a long time without warping or cracking.

Suggestions regarding toilet environments during disasters
We propose the establishment of a sanitary and safe toilet environment for disaster victims.
One of the major concerns for evacuees during evacuation life due to disasters such as earthquakes is the use of toilets. In recent years, the occurrence of natural disasters such as earthquakes and floods has increased, highlighting the need for the establishment of a sanitary and safe toilet environment for disaster victims to use during emergencies. In response to this, we propose considerations for toilet facilities during disasters based on three perspectives: "treatment methods," "toilet functions," and "surrounding environment." For toilets during disasters, there are treatment methods such as the "manhole direct connection type," which is hygienic and has no limit on processing volume as it discharges directly into the sewer system, and the "underground pit type," which can be used in areas without sewer systems or in areas that have not been earthquake-proofed and does not require flushing water. We also suggest toilet iron covers suitable for these treatment methods, as well as toilet tents, buildings, and bowls. Additionally, we provide products such as solar-powered lighting, pumps, and signage for the surrounding environment. *Products are manufactured by Hinode Water Supply Equipment Co., Ltd. (Sales support available in the Kinki region, including 2 prefectures and 4 counties) For more details, please contact us or download the catalog.

[Maintenance Construction Case] Integrated Drainage Work
We propose a project to integrate the cover and the drainage ditch! A case where the work was completed without affecting operations.
Asphalt depression at the truck stop (for unloading work with a lift). When we carried out repair work, we noticed that the concrete cover of the drainage ditch had noticeable cracks. Upon removing the cover for inspection, we found that the edges were significantly chipped as well. When we reported this to the customer, they consulted us, saying, "Since trucks and lifts pass through here every day, we want to take measures to ensure safety, but is there a cost-effective solution?" Initially, we planned to replace only three severely damaged areas, but it turned out to be more cost-effective to address the entire area, so we integrated the drainage ditches for the entire truck parking space. Additionally, we installed a grating in the center for drainage during rainy weather. 【Case Summary】 ■ Industry: Manufacturing ■ Request: Repair of drainage ditches ■ Work Details: 1 day *For more details, please refer to the PDF document or feel free to contact us. Key service areas: Mie Prefecture, Kitasei District, Chusei District (surrounding Mie).
