2,426 bridges
80,824.48 m of good bridge manufacturing.

"Without a bridge, you cannot get across" -- An old adage describing the fact that things will not go well without a liaison between them.
Bridges are symbols of creating bonds.
Yada Industry, established in 1949 (later to become Yada Industry Co., Ltd.) has always implemented and developed the most cutting-edge technology and has developed unique proposals in the area of steel structures, such as steel bridges, water gates, and water pipelines.

Since 1959, when we built our first bridge, "Hiwada Bridge," with "Building Good Bridges" as our motto, we have built 2418 bridges equaling a distance of 80,384.58 m (as of March 2019) in our hometown of Fukushima and across the country. That number includes bridges connecting opposite canyon ridges and river shores, viaducts making it possible to cross over roads, and overpasses making it possible to cross railroads.
Measures to extend the life of infrastructure such as bridges, is now an urgent issue throughout Japan.
As a company that plays a role in the structures that form the basis of society and economic activity, Yada Industry integrates the power of design, production, and on-site management to fulfill our responsibility as a company that has the one-and-only comprehensive capability.

National Route 289 connects Iwaki City along the Pacific coast of Fukushima Prefecture and Niigata City on the Japan Sea coast of Niigata Prefecture via Shirakawa City.
The 3-span continuous Lohse-type arch bridge stretches across a length of 199 m over the steep gorge of the Abukuma River source.
Since its installation in 2003, it has become a scenic tourist destination with many visitors coming to see the new greenery of spring and the changing leaves of autumn.

  • Using our design power to make proposals.

    We grasp the required functions in relation to cost, manufacturing, and construction to improve the value of bridges.

    We consider all elements of the drawings and documents submitted, such as compatibility of design conditions, site conditions, manufacturing conditions at the factory, erection method, etc. upon which we will then create production approval request drawings after verifying the consistency of the design with wire use calculations, stress calculations, quantity calculations, etc. Yada Industry's Design Department regards this verification procedure as an essential process in achieving VE (Value Engineering).
    The person responsible reviews the 2-D drawings and gains an understanding of them and uses CIM (Construction Information Modeling) to transform them into 3-D model data, always conducting verification with the image of the finished product in mind.
    We create various proposals based on awareness and ideas born from perceptions and inspiration that goes beyond simple verification, such as optimal designs for the topography and geology, accurate construction procedures to prevent "reworking."
    Yada Industry's verification is not merely a simple process for confirmation and approvals. It is a task that requires great creativity.

  • Manufacturing with production power.

    With our vast factory, the latest equipment and machinery, and our extremely talented workforce, we are highly committed to the construction industry.

    Our 25×300 m and 25×230 m provisional assembly yards, 23×235 m BOX yard, 23×233 m PLATE yard, 20×150 m paint plant, and our 4,000m² Motomiya Materials Center ― Yada Industry boasts factories of a scale that makes it one of the largest in Fukushima and throughout Japan.
    The existence of an immense space that allows collective actual temporary construction is a major advantage to the value engineering of bridges.
    The factories use cutting-edge equipment to perform cutting, drilling, assembly, welding, provisional assembly, and painting under precision factory management and meticulous quality control.
    We are also putting great effort into educating our talent.
    A veteran employee is assigned to each new employee for one-on-one instruction. They exchange a notebook asking questions and providing answers daily, and through continuous on-the-job training (OJT) we seek to improve employees' abilities (knowledge, technique, qualifications, and the ability to implement them).

  • Installing with on-site management power.

    We build good bridges while maintaining safety and strictly adhering to the construction period and taking the scenery and environment into consideration.

    Yada Industry has installed 2,418 bridges (as of March 2019), and though it may seem too obvious to mention, none of these bridges are the same.
    It is always a new challenge to determine the topography and geology that satisfies the requirements of the bridge in addition to plan, design, manufacture, provisionally assemble, and construct a bridge with the materials, form, and construction methods optimized for the construction period and budget.
    Even bridges, which are the best and most ideal bridges up to the point of provisional assembly, will require flexible and tough on-site management to make them a reality.
    In terms of form, there are steel girder bridges, box girder bridges, truss bridges, rigid--frame bridges, arch bridges, cable-stayed bridges, suspension bridges, and pedestrian bridges. In terms of construction methods, bent method, cable-stayed method, erected girder method, incremental launching method, cantilever erection method, and single-operation erection.
    Consideration must also be given to the landscape and the burden on the environment.
    Yada Industry has its own proprietary materials and equipment, as well as engineers and laborers with a wealth of on-site experience for building good bridges for every situation and location.

    Across the country, large numbers of bridges are aging resulting in corrosion and deterioration.
    Nothing is more important than the safety and security of infrastructure, including that of bridges.
    At Yada Industry, we use the technology we have cultivated over time to engage in field surveys, repair, reinforcement, seismic reinforcement, and deconstruction of bridges and water gates,
