Steel Bridges

For the past 80 years, Kawada Industries, Inc. has been renowned in Japan as one of the foremost builders of steel bridges. During this time, we have been involved in practically every major project in the country, and have been involved with more than 4,000 steel bridges. Today, we complete approximately 60 bridges each year in Japan alone.

It is precisely this experience, plus our access to resources, and our renowned quality and efficiency, that has made Kawada Industries, Inc. famous across the world for steel bridge construction. We are able to undertake projects of any size, and can offer a suite of services, including steel bridge design, fabrication, technical assistance, erection engineering, value engineering and supervisory activities.

STEEL AND CONCRETE COMPOSITE DECKING SYSTEM (SC DECK)

Our SC Deck system is a lightweight, permanent steel formwork that is ideal for structural launching and can completely replace conventional formworks. SC Deck reduces the number of workers required on site, decreases costs and improves safety levels.

STRUCTURAL FEATURES

Our long-span decks offer exceptional durability while reducing weight thanks to our adoption of a thinner steel plate. They can be adapted to a number of road configurations, including widened, curved and oblique-angled road types, and are suitable for open-box girder and minimal-girder bridges.

CONSTRUCTION FEATURES

At Kawada Industries, Inc., our construction materials and methods offer tangible benefits to our customers. Our use of lightweight under-steel plate makes delivery and installation easier, and removes the need for complex erection methods. Our stiffening functions allow for hassle-free launching and side shifting, as required. Finally, there is no need for traditional timber formwork, making our system suitable for challenging projects, such as overpasses and deck repairs.

PREBEAM BRIDGES
(PREFLEXION BEAM BRIDGES)

Prebeam Bridges have evolved in response to the constant needs for greater sophistication in various ways. The Prebeam, developed in Japan, is a preflexion steel-concrete composite beam into which the internal stresses are introduced by the preflexion method. Compared with other bridge types, the Prebeam structure enables girder depth to be extremely thinner, allowing its application to many of the bridge and building beams or girders requiring thinner depth. Now, the industry has a proven track record of its application to more than one thousand bridges.

Service Flow

No two bridges are alike, but our standardised service flow ensures unmatched quality for every project.

Bridge Maintenance

We also ensure the longevity of each bridge by providing extremely high level of maintenance after completion. This includes seismic strengthening, inspections for fatigue cracking, related retrofitting engineering services, and R&D efforts.

Kawada Industries, Inc. is one of the players undertaking the major renewal project for the approximately 1.9-km section on Route 1 (Haneda Line) of Metropolitan Expressway, which connects between Haneda Airport to cities of Tokyo.

After more than five decades since the opening in 1963, the Route 1 had been subjected to extremely heavy daily traffic and harsh environment where the viaduct is set very close to the seawater level, making it too difficult to address various damages through conventional inspections and repairs. This major renewal project reconstructs the road structure excelling in durability and maintenance for the entire section to ensure a long-term safety, now attracting much attention.
