Fibreglass (FRP) Working Platforms for High Corrosion Resistance

At a copper refinery located in Piedras Verdes, Mexico, Strongwell’s fiberglass operating platforms and walkways totaling over 10,000 square feet were installed to withstand corrosion. The refinery employs solvent extraction electrowinning (SXEW) process for copper extraction from the ore. The process involves the use of an electrolyte liquid, which is highly corrosive to steel and aluminum. Hence, corrosion resistant FRP structural platforms, handrails and grating were chosen for the project.

Benefits of FRP over Steel and Aluminum

The FRP platforms have high durability when compared to steel and aluminum and their low electrical conductivity ensures the safety of workers. Moreover, the installation of FRP handrail, grating and shapes was much easier and faster thanks to their light weight.

FRP platforms

FRP platforms are the ideal solution for use in corrosive operating environments such as SXEW process used in copper refineries. This makes fiberglass the material of choice for such kind of operations.
