Protect your civil infrastructure

Variable message signs or VMS are used across a wide range of applications, including traffic control.

The largest part of traffic signals along bypass roads and highways are connected to concrete by anchor bolts that are often hot dip galvanized (HDG) coated. HDG coating, however, is proved not to be enough to protect the bolts against corrosion and this can result in severe damage for the anchoring system integrity.

In this application, studied for one of the main Italian Highway autority, prior to install BA-FPRO ALU (aluminium made) caps, corrosion inhibitor grease was generously and evenly applied to the bolts, so as to preserve them from corrosion.
