Recruitment of Ambassadors (a few positions available) for the "100-Year Bridge Project," which promotes the charm of civil engineering and bridges together.

A newly constructed bridge requires no replacement for 100 years! Long-term water resistance, maintenance-free.

In the longevity of bridges, the durability of expansion joints is a very important factor. Replacing expansion joints requires significant costs and traffic regulations, which can reduce the operational efficiency of bridges. The Hybrid Joint Type 3LII achieves a durability of 100 years, contributing to cost reduction and improved safety from a long-term perspective. 【Application Scenarios】 - New bridges - Repairs of existing bridges - Highways * For general roads, there is the "Hybrid Joint Type 3LIIA." 【Benefits of Implementation】 - Reduction in lifecycle costs due to no need for replacement for 100 years - Maintenance-free, eliminating the need for sound inspections and ultrasonic inspections, reducing maintenance costs - Decreased frequency of traffic regulations, mitigating traffic congestion and noise damage, and enhancing safety - Adoption of new technology through NETIS registration (No. KT-210067-A)

A bridge expansion device proven to last 100 years! No replacement needed for new bridges for 100 years! Long-term water-tightness, maintenance-free [NEXCO specification compliant product].

The Hybrid Joint 3LII type has a vertical integrated structure of the load support plate and anchor plate, making it highly durable and preventing damage from metal fatigue. Its durability is equivalent to an ultra-long term of 100 years! It has been proven through fatigue loading tests conducted by a third-party organization, clearing the equivalent of 12 million cycles, which corresponds to 100 years. This assumes that a 25-ton large vehicle has traveled over the 3LII type 12 million times, equating to a 100-year durability. The standard design supply period for bridges is 100 years. For newly constructed bridges, there is no need to replace the expansion device for 100 years. The 3LII type is maintenance-free, eliminating the need for sound inspection that requires traffic regulation, leading to reduced maintenance costs and improved safety. It is a product capable of accommodating large expansion ranges (150-350mm) and wide gaps (up to 730mm), making it one of the largest among expansion devices that have passed NEXCO standards. It has been widely adopted on highways nationwide as a product that meets NEXCO specifications. For more details, please contact us or request a catalog.

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.

Products for wall and ceiling use with gypsum boards, as well as items for RC construction renovations, have been added to the listings released last year. New construction examples have also been added, which can be used to propose ideas to customers considering renovations. Please utilize the subsidies from the Mirai Eco Housing 2026 project for proposals on insulation renovations combined with water area and window improvements.

We would like to express our sincere gratitude for your continued support. As you may be aware from recent news reports, the situation in the Middle East has deteriorated rapidly, leading to an increase in the prices of raw materials originating from that region. Consequently, there is a possibility that the prices of our products may also rise in the future. Please be advised that due to fluctuations in the market conditions of raw materials, we may change prices without prior notice, and we appreciate your understanding in advance. Additionally, regarding product delivery times, we are currently operating as usual. Should there be any changes in the future due to the situation, we will inform you accordingly. We apologize for any inconvenience this may cause and thank you for your understanding.

The initiatives of our parent company, Inbacks Co., Ltd., have been featured in the web media ZEROICHI.

The bridge expansion device manufacturer, Crittec Co., Ltd., is seeking a few ambassadors for the "100-Year Bridge Project," who are interested in the civil engineering and bridge fields and can share their appeal and social issues through social media. This initiative aims to raise awareness about the current state of aging social infrastructure and the importance of maintenance and management. We welcome individuals with interest or knowledge in civil engineering and bridges as ambassadors to collaboratively plan, create, and disseminate content, thereby promoting understanding and revitalization of social infrastructure as a whole. Would you like to share the interesting aspects and importance of social infrastructure through your perspective and creative activities? We welcome those who are engaged in creative activities or information dissemination related to civil engineering and social infrastructure, as well as those who wish to take on new challenges. The number of followers does not matter. Your "likes" and "messages" may connect to the future of social infrastructure. Please feel free to apply.
