[Product Introduction Case] Great Naruto Bridge Repair Work

In a harsh environment constantly exposed to sea breezes! We will introduce examples of repair and prolongation coatings for galvanized surfaces.

In 1995, approximately 10 years after its completion, repair work was carried out on the lighting columns of the Great Naruto Bridge. Here is an introduction to that case. The lighting fixtures illuminating the road on the bridge were originally galvanized, but due to the harsh environment, the zinc consumption was severe, leading to the occurrence of spot rust. As a rust prevention measure, a product called Robal was used for repairs on the mounting parts of the lighting fixtures and the base, which required particularly high strength. Even during a site inspection eight years after the construction, no rust was observed. 【Case Overview】 ■ Before Construction - Due to constant exposure to sea breeze, zinc consumption was severe and spot rust occurred. ■ Eight Years Later - No rust has developed from the areas that were repaired and extended using Robal over the galvanized surface. *For more details, please refer to the PDF document or feel free to contact us.
