The metal road construction method is suitable for road construction in mountainous areas. It is a three-dimensional frame prefabricated bridge consisting of a grid section and a floor slab, primarily made of steel pipes and H-shaped steel.

The "Metal Road Construction Method" is a three-dimensional frame prefabricated bridge where the piles, cross beams, and main beams are rigidly connected at the grid points. It is mainly suitable for road construction on steep slopes in mountainous areas. We apply the appropriate structural type according to the terrain and construction conditions. We offer various types, including the "Widening Type," "Mountain Side Cantilever Type," and "Independent Type." 【Features】 ■ Excellent seismic resistance ■ Easy transportation and installation of components ■ Short on-site construction period ■ Widening possible while ensuring existing traffic ■ Consideration for the natural environment ■ Abundant track record *For more details, please refer to the PDF materials or feel free to contact us.

This is a reinforcement method for RC members using lattice steel plates (steel plates processed in a lattice shape). The reinforcement cross-section can be made thin, and it can reduce labor on-site.

Grid metal is a product that reinforces deteriorated RC structures by integrating with polymer cement mortar. By processing steel plates into a lattice shape, it allows for a thinner reinforcement layer, making on-site work more efficient. It is used for reinforcing the underside and topside of bridge RC slabs, repairing and reinforcing deteriorated box culverts, and reinforcing RC beams. By reducing the thickness of repairs, it enables a reduction in repair loads and ensures the maintenance of internal space. Features of the grid metal method: - It can be processed in the factory to match the shapes of tunnels and box culverts, thus streamlining on-site construction. - Since the vertical and horizontal bars are on the same plane, the reinforcement cross-section can be made thinner, minimizing the increase in dead load and favorably securing internal space. - By applying corrosion protection treatments such as hot-dip galvanizing and epoxy resin coating, it excels in corrosion resistance and contributes to the longevity of structures.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers.

JOHNAN has updated a webpage summarizing the selection points to solve various challenges in large-scale processing (quality maintenance, short delivery times, costs). This article introduces the challenges faced in large-scale processing based on years of knowledge and experience, as well as the key points for choosing the optimal contractor that balances quality and short delivery times. If you are looking for a reliable contractor, please make use of our "Large-Scale Processing Solutions." ▼For more details "Large-Scale Processing Solutions to Achieve Product Quality and Short Delivery Times" https://www.johnan.com/solution/process/processing-assembly/post_8.html

Thank you very much for your continued support. We sincerely apologize for the inconvenience, but our company will be closed for summer vacation during the following period. 【Closure Period】 From Saturday, August 9, 2025, to Thursday, August 14, 2025. We will resume normal business operations on Friday, August 15. We appreciate your understanding during this time and apologize for any inconvenience caused.

JOHNAN has released a video that clearly explains the implementation technology for stretchable films, which are expected to be utilized in wearable devices and medical equipment. In the video, you can see how the film, which has excellent elasticity, stretches and contracts. Please check our high technological capabilities and the flexible characteristics that are useful for product development. We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
