TRAILER MYTH: A galvanised chassis can't rust. ๐ค
Not quite! ๐
Galvanising provides excellent protection against rust, but not all galvanised chassis are created equal.
There's a big difference between pre-galvanised steel (often called DuraGal) and a fully hot-dip galvanised chassis.
๐ง Pre-galvanised steel (DuraGal) is coated with zinc before it's cut and welded into a chassis. The zinc coating is relatively thin, and cutting and welding can leave areas where the original protection has been removed, requiring additional treatment.
๐ง Hot-dip galvanising happens AFTER the chassis has been fully fabricated and welded. The entire chassis is dipped into molten zinc, creating a substantially thicker protective coating, including over the welds and accessible internal surfaces.
That's why we hot-dip galvanise every KT chassis. ๐ช
It provides far superior long-term corrosion protection, but here's the thing...
Even a hot-dip galvanised chassis isn't completely maintenance-free.
Over time, stone chips, scratches, road grime and exposure to the elements can take their toll.
A little TLC goes a long way! Give your chassis a regular clean and inspection, particularly after exposure to salt or coastal conditions.
And if you notice any areas where the zinc coating has been damaged or surface rust is starting to appear, address them early with proper preparation and a suitable zinc-rich coating.
Hot-dip galvanising gives your chassis a great head start. A little maintenance helps keep it that way. ๐
