This is a grating for the upper lid type U-shaped drainage channel (PU1 type) compliant with JIS A 5372. It is referred to as "flanged grating" due to its feature of being hooked onto the drainage channel with L angles on both sides. Flanged types are commonly used in agricultural waterways, particularly in bench flumes, but due to the larger taper on the inside of the drainage channel, it is necessary to increase the size of the angles. The vehicle direction for U-shaped channel gratings (flanged type) is only for longitudinal use. Please note that it is not intended for use in areas where vehicles cross (except for special designs). It is listed as a general product (high-tensile steel grating) and can be widely used in both public and private construction projects. The main material uses high-tensile steel, which has higher strength than conventional steel, achieving an average cost reduction of 2% compared to SS400 steel gratings of the same standard, along with weight reduction and approximately 25% reduction in CO2 emissions during manufacturing and transportation. It accommodates a wide range of specifications from coarse to fine, transverse and longitudinal, and load capacities from T-2 to T-25.

The ultra-fine type of high-tension levee grating is a barrier-free grating that reduces gaps to just 5mm by placing two auxiliary members. It is ideal for high-traffic areas such as commercial facilities, station fronts, and sidewalks, as it minimizes the chances of high heel heels, wheelchair wheels, and stroller wheels getting stuck. The narrow gaps also make it difficult for cigarettes and fallen leaves to enter, contributing to a reduction in cleaning frequency. By adopting high-tensile steel, it achieves weight reduction while maintaining the same material thickness and pitch as conventional fine-grained gratings. It is suitable for a wide range of applications, including various concrete secondary products, cast-in-place gutters, and catch basins, with load capacities ranging from pedestrian use to T-25.

Is there a place you would like to regenerate or extend the lifespan of? - Circular water channels in highway tunnels - Circular water channels with pedestrian and vehicle road blocks on top - Elevated circular water channels - Locations where replacing ditches is difficult - Areas where construction affects underground structures - Urban ditches located at sidewalk boundaries, etc. Product Overview The optimal repair method for aging circular water channels "Top Shield Method" The Top Shield Method is a repair technique that uses formwork to repair existing circular water channels (pipe-type ditches). It involves vertically cutting the deteriorated parts of the circular water channel and repairing them with a dedicated formwork (high-tensile steel residual formwork) and jet concrete. The formwork integrates with the structure without being removed. Advantages Environmental: Reduces the generation of construction waste Durability: Resistant to rust with standard specifications of molten zinc coating Workability: Shortens construction time (construction volume: approximately 20 meters per day, self-calculated) Safety: Uses high-strength high-tensile steel (high-strength steel)

The Calvert Creator is a buried cover made from "high-tensile steel," which has a higher strength than conventional SS steel materials. By installing the Calvert Creator in existing ditches and paving over it with asphalt, quick and durable drainage construction can be achieved. There is also a buried cover with slits or grating called the "Slit Creator."

As the population ages, a budget was allocated to introduce spring-operated snowmelt gutter grates. Residents were thrilled with the light opening and closing during snow removal! However, a few years later, the device deteriorated, resulting in the same heavy standard grates as before... If that was the case, it would have been better to use standard snowmelt gutters from the beginning and allocate the funds to other maintenance costs. Therefore, we now have lighter snowmelt gutter grates without the weight reduction device.

Operation of the weir board necessary for water division and flow adjustment to the rice fields. Isn't it difficult to lift the large manhole cover? As the manhole increases in size, the cover becomes heavier, and there is also a risk of falling from the wide opening. Many of the weir boards used in collection manholes are installed by constructing a gate with a vertical groove called "kakuro" at the connection point with roadside ditches or agricultural waterways, which is inserted into the inside of the manhole. Therefore, when operating the weir board, it is necessary to open and close the manhole cover grating. For this reason, we recommend the "high-tension grating weir board pocket" that allows for water division and flow changes to the rice fields without opening the large manhole cover.

When you are troubled by overflow from waterways or the inflow of sediment, traditional methods involved assembling formwork to raise the height with poured concrete or using concrete piles and boards to elevate the walls of the waterway. However, the work was often affected by weather conditions, and in places where heavy machinery could not access, it took a long time to install heavy materials manually. Therefore, the EZ Metal Wall is a high-tensile steel retaining wall that allows for easy elevation work simply by digging alongside the waterway and hanging it on the side walls.

It can be installed in just a few hours, resulting in a quick construction period and allowing for immediate traffic reopening. Additionally, it enables significant weight reduction and functional improvements of the lid simultaneously with repairs, thereby solving various issues on-site. Structure of Liftus This method involves setting a frame that is slightly smaller than the existing lid like a "nested" structure and filling the gap with grout material (non-shrink mortar) to secure the lid support and the new receiving frame. Both the lid and frame are made of high-tensile steel, which has a higher strength than conventional steel. The grating is lightweight while still satisfying the conventional strength standards.

Gorihalcon for countermeasures against corner chipping of concrete gutters and damage at crossing sections. Is it okay to leave the entrance as it is? We can accommodate both retrofitting during new construction and repairs for existing installations. When vehicles frequently cross over the longitudinal gutters at store entrances, they may not withstand repeated loads and impacts, leading to cracks and chipping in the concrete. Therefore, Gorihalcon is a high-tensile steel retrofitted protective plate installed to cover the rising part of the longitudinal gutter, preventing concrete cracking and chipping.

The vacuum grating is a disaster prevention type grating equipped with high drainage capacity and standard anti-theft features. It was developed in response to the recent increase in concentrated heavy rainfall and the series of grating theft incidents. Utilizing a special vacuum structure made from robust high-tensile steel, it maintains sufficient drainage performance even with a significant reduction in size compared to previous models, contributing to a reduction in environmental impact through weight reduction.

Almost all of the grates that are stolen nationwide lack fixed or restraint features. The absence of grates can lead to unexpected accidents such as vehicle rollovers, wheel detachment, and children falling. For raised grates suitable for road ditches, variable ditches, and underground ditches, we have solutions that cover about 90% with two types of fittings.

FRP stands for Fiberglass Reinforced Plastics, which is a composite material made from resin and glass fibers. The resin is strong against water, chemicals, and heat, while the glass fibers have high strength characteristics. General type: a standard type that excels in acid and salt resistance. Corrosion-resistant type: compared to the general type, it is stronger against acids and alkalis, making it ideal for places that handle chemicals. Flame-retardant type: compared to the general type, it has self-extinguishing properties and does not allow flames to spread, making it suitable for wall materials, fence materials, and places that handle hot items.
