The choice of using galvanized etrack or painted e-track can be based on three factors: price, color and installation location.
Painted e-track is slightly cheaper than its galvanized sibling. But for the most part – galvanized is only a couple dollars more, because of the process used to treat the metal.
E-Track’s color is also based on which version of etrack you are buying. Galvanized is a silver color – which can help it blend in if you are looking for a solution to match aluminum. It is slightly more reflective than aluminum.
Painted etrack is green and powder coated – which makes it resistant to scratching and will hold up well to daily use.
Finally we get to what kind/where you plan to install your e-track. If the installation is on the exterior, then the best choice will be galvanized. This treatment provides the best resistance to elements in the e-rack lineup.
