Many homes have block walls that have significantly exceeded their durability. As a safer alternative to these dangerous block walls, we have researched and developed the "Super Fence" in collaboration with Kansai University, which is lightweight and earthquake-resistant. The surface material is wood, while the posts and caps are made of aluminum, creating a hybrid privacy fence. It can accommodate heights of up to 3 meters and features easy installation and environmental conservation. Easy installation means that, quite literally, the method using thinned wood compared to traditional block walls is simple to construct. Environmental conservation can be achieved by using thinned wood. The privacy wood fence can reach heights of up to 3 meters. By inserting acrylic panels or aluminum between the thinned wood, it is also possible to create a fence with an original design.

Since our establishment, we have developed (designed and manufactured) metal products using iron, aluminum, and stainless steel in various categories such as "architectural hardware," "civil engineering materials," "marine hardware," "temporary hardware," "logistics equipment," and "exteriors." In product development, we repeatedly conduct strength tests, including tensile tests, load tests, and drop tests, which are related to safety and security. Indeed, it is only by testing products to their limits that we can understand their boundaries. If a product's strength can only be assessed theoretically, it leaves a lingering sense of uncertainty. By testing, we transform that uncertainty into a tangible form, ultimately creating products that we can confidently sell. When you entrust us with your needs, we will resolve uncertainties and shape them into reality, backed by development support grounded in strength testing. Our goal is to embody our customers' needs through "one-of-a-kind manufacturing that ensures safety and security." Please feel free to contact us for more details.

The "Telescopic Overheight Attachment" is an attachment whose length can be adjusted to fit different types of container boxes (20ft, 40ft, or 45ft). The connection method and twist lock operation are the same as those of the overheight attachment. Additionally, the telescoping mechanism is linked to the spreader of the gantry crane. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the height of the overheight attachment. For more details, please feel free to contact us.

The "Overheight Attachment" is a lifting device used in conjunction with the spreader of gantry cranes at port facilities. It is designed to grasp boxes containing cargo that exceeds the height of standard container boxes (8.6ft/9.6ft). The connection to the gantry crane's spreader is made using a connecting pin. Additionally, the twist lock operation of the overheight spreader is linked to the gantry crane's spreader. Therefore, when the gantry crane's spreader is locked, the attachment side is also locked, and the unlocking operates in the same manner. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the overheight. For more details, please contact us.

• System kitchen equipment and accessories

The "Overheight Spreader" is a lifting device used in conjunction with the mother spreader of gantry cranes and transfer cranes at port facilities. It is designed to grasp open-top containers or flat rack containers loaded with cargo that exceeds the height of standard container boxes (8.6ft/9.6ft). The connection between the mother spreader and the overheight spreader is made using the twist lock of the mother spreader, and the operation of the twist lock on the overheight spreader is performed manually using wire ropes arranged on the side. Each product generally conforms to the dimensions of ISO container boxes, but the specifications for leg length, lifting capacity, and self-weight vary depending on the overheight. For more details, please feel free to contact us.

A power conditioner (power con) is a device that converts electricity generated by solar panels (modules) and Enefarm (home fuel cells) into a form that can be used in households. The electricity generated by solar panels is "direct current," and the power conditioner plays a role in converting this into "alternating current" for usable electricity. To independently install a power conditioner on land, a dedicated structure is required. This is where the "power con" storage container, which utilizes a container as the structure, comes into play. It is easy to install and move, and offers excellent cost performance. Additionally, it is attractive because it qualifies for favorable treatment from the government, as it does not fall under the category of "storage tanks and other similar facilities" as defined in Article 2, Item 1 of the Building Standards Act. For the construction of solar power generation (especially mega-solar), please consider the "power con" storage container from Port Seiki Kogyo, which is easy to install, move, and dismantle, and is also environmentally friendly.

If the electricity generated by solar power systems cannot be stored, the surplus electricity is wasted. Therefore, various types of batteries such as lithium-ion, lead, and nickel-hydride are necessary for storing electricity, along with specialized structures for independently installing them on land. The storage container for batteries utilizes containers, making installation and relocation easy and offering excellent cost performance. Moreover, it is attractive that it qualifies for preferential treatment from the government as it does not fall under the category of "storage tanks and other similar facilities" as defined in Article 2, Item 1 of the Building Standards Act. For the construction of solar power generation (especially mega-solar), please consider the battery storage container from Kōsei Kōgō, which is easy to install, move, and dismantle, and is also environmentally friendly.
