TRAILER GALVANIZATION INFORMATION

Why is the galvanized coating on my trailer rough and mat?

The rough and dull appearance of your trailer coating is a result of the dipping process where the parts are immersed in melted zinc. The formation of rough spots is due to an uneven adherence of zinc to the parts, especially the non-symmetrical or complex ones. The evenness of the coating would further take about 18 months to achieve, due to the natural tendency of the zinc to mature with time. This could also be attributed to the inherent stability of certain steel types that might contribute to a duller appearance. Nonetheless, this process doesn’t compromise the protective ability of the coating against corrosion. In the event that yellow stains appear, rest assured that this signifies the onset of the process to develop an even coating, and these marks will soon disappear.

How long will a hot dipped galvanized steel trailer last?

The durability of a hot dipped galvanized steel trailer relies heavily on several factors, including the thickness of the protective coating and the steel’s type used to construct the trailer itself. Triumph Trailers, for example, feature a 70-micron galvanized coating. However, extended exposure to moisture, air pollutants, and road debris can shorten the lifespan of the trailer. It is vital to maintain the trailer in good condition to retain its anticorrosive properties. Regular upkeep, including washing and inspecting the trailer for any defects and promptly repairing them, is crucial. This enables the trailer to stay in good condition and maintain its strength and longevity over time.
