We developed an automatic machine for the waterproof coating work of wall handrails on of the Metropolitan Expressway.

For substrate adjustment, we developed a mist jet using a water jet.

For SQS painting work, we developed an automatic painting machine equipped with a spray gun.

Some test painting works were carried out on the route 1 and route 9 of Metropolitan Expressway.

This enabled efficient and high-quality construction.

As a result, it was confirmed that the number of traffic restrictions could be reduced significantly.
