The new "2024-2025 Comprehensive Catalog" has been released! New grating products included! β

A safety walker installed at a famous ramen shop as a measure for large vehicle entrance and exit. Its structure features a flat top surface, making it durable, resistant to clogging, and lightweight.

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. They can be useful in various scenes. They are suitable not only as grating for on-site pouring 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 their structural design, the surface material structure makes them strong against twisting and impacts from vehicle tires, making them very resistant to breakage. They are also ideal for preventing grating damage. Additionally, the design makes it difficult for stones and debris to clog the grating itself, preserving the landscape. 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 exceeds that of conventional types. If you frequently experience grating damage near entrances and exits, you will realize that these are different from conventional grating. *For more details, please refer to the PDF document or feel free to contact us.

New model of 'Fine Great' launched! Exhibits high durability performance under torsional loads! OG Super High Tensile High Strength Stainless Steel Grating.

We would like to introduce the new model "OG Super High Tensile High Strength Stainless Steel Grating" handled by Okagreat Co., Ltd., specifically the "Fine Grate" (U-shaped drain type). The material used is NSSC low-alloy type duplex stainless steel, which boasts about twice the strength of SUS304 stainless steel. We have improved the manufacturing process of the OG Super High Tensile High Strength Stainless Steel Grating! It exhibits high durability performance against loads in the "twisting" direction! The new model combines the uneven parts of two components for bonding. This structurally enhances strength and achieves even higher load-bearing performance. It also demonstrates high durability performance 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.

Clean rivers and oceans, gentle on the Earth. A fusion of screens and grates for catching trash. 'Screen Grate'! Preventing waste from flowing downstream.

We would like to introduce the "Screen Grating" handled by Okagreat Co., Ltd. We have been hearing more news about marine pollution caused by plastic waste. Various industries are making efforts to reduce plastic waste, such as charging for plastic bags and switching to paper straws. This "Screen Grating" integrates the grating and the debris screen, which were traditionally installed separately, achieving significant cost savings. It is installed at the edge of the drainage channel to prevent debris from flowing into the interior, and when the screen is not in use, it can be easily stored in the grating body with a one-touch mechanism. Removing accumulated debris is also simple. It is suitable for U-shaped channels for concrete secondary products and for raised grating for longitudinal use, among others. (The photos show the "U-shaped channel type" and the "JIS drainage channel type.") Please feel free to consult us regarding U-180, U-240, U-300, special dimensions, custom sizes, and concrete secondary products. If you have any inquiries, please do not hesitate to 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.

PERI products are used at construction sites around the world. This time, we would like to introduce the construction work of the "Dunajec Road Bridge" spanning the Dunajec River in the town of Nowy Targ in southern Poland. The road bridge was planned to be constructed using a balanced cantilever method, dividing the cantilever beams starting from each pier into 10 segments. A particular concern was to strictly adhere to the concrete pouring cycle for each segment. To achieve this, a balanced cantilever carriage (VBC) equipped with a hydraulic advance system and an automatic formwork stripping function was adopted. By utilizing the VBC, it became possible to pour concrete for segments up to a maximum length of 5 meters in a single cycle, allowing for efficient and timely construction. PERI products: 1. TRIO Panel Formwork 2. VARIO GT24 Wall Formwork 3. PERI UP Flex Modular Scaffold 4. VST Heavy-Duty Shoring Tower PERI Japan Co., Ltd.
