We have renewed our homepage. A variety of the latest grating products are now featured. (Okagrate Co., Ltd.)

A safety walker installed at a famous ramen shop as a measure against large vehicle entrances and exits. It is structurally resistant to clogging, durable, and lightweight. The flatness feels great.

The "Safety Walker G・D" and "Safety Walker L・D" are advanced grating systems 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 appealing 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 grating for on-site casting but also for various types such as drop-in, bolt-fixed, raised types, and other specially sized covers (please consult us for concrete precast products, etc.). Due to their structural design, the surface is made of a material structure 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 created in the "striped steel plate" or "patterned steel plate" on the surface, balancing drainage and strength. Furthermore, it has been reported that the slip resistance exceeds that of traditional models. If you frequently experience damage to grating near entrances and exits, you will likely realize that this is different from conventional grating.

The new model of OG Super High Tensile High Strength Stainless Steel Grating, "Fine Great"! It demonstrates high durability performance even under loads in the "twisting" direction!!

We would like to introduce the new model of OG Super High Tensile High Strength Stainless Steel Grating, 'Fine Grate (Fine Pitch 15)' (U-shaped drain type), handled by Okagreat Co., Ltd. The manufacturing method of 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 features a combination of the uneven parts of two components that are joined together. This structurally enhances strength and achieves even higher load-bearing performance. It exhibits high durability against "twisting" loads caused by "vehicle tires," which has been a weakness of conventional products. Additionally, 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 in a "scattered state" due to loads from "vehicle tires" and "twisting." This product has been improved through a new manufacturing method to address such issues. *For more details, please refer to the PDF document or feel free to contact us.

"Safety Walker" installed at golf courses of companies listed on the Tokyo Stock Exchange Prime. It is designed to be resistant to clogging, durable, and lightweight. It has a good flat feel.

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, ensuring they remain hygienic at all times. They also have an appealing appearance and are less likely to break due to their surface material structure, making them useful in various scenarios. These products 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-sized 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 particularly durable and ideal for preventing damage. Additionally, the design minimizes the likelihood of stones and debris clogging the grating itself, preserving the aesthetic appeal. Multiple slit holes are incorporated into the "striped steel plate" or "patterned steel plate" on the surface to balance drainage and strength. It has also been reported that the slip resistance exceeds that of conventional types. If grating frequently breaks near entrances and exits, the difference is easily noticeable when passing through with a golf cart or similar vehicle. You will truly feel that it is different from conventional grating.

Are you making progress on measures for the "2024 Problem"? The management of drivers' working hours is becoming stricter, and in the logistics field, reducing "waiting time for loading" has become an urgent issue. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability status, reducing unnecessary waiting and queuing, and shortening waiting times, thereby alleviating the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start taking measures against the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult us first.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four configurations: left, center, right, and a total of 12 spots. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor with a single model. 【Recommended for such locations!】 ☑ Entrance facing a busy corridor ☑ Counter or sign near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
