We strive to improve our products by considering the issues that arise during installation and the condition of the removed existing expansion devices. 【Construction Case】 ○ Location: Chiba Prefecture ○ Bridge Name: Heisei Bridge ○ Products: NS-20 and others ○ Comments: Due to the bridge's proximity to the coast, we conducted the work while confirming the corrosion of rebar and the deterioration of concrete caused by salt damage.
