Maintaining The Trailers Galvanized Surface

Your Dunbier trailer is coated in a galvanized finish, where the trailer has undergone a chemical process that bonds very hot liquid zinc to

the trailer and it's components, becoming part of the base metal below it. The zinc covering forms a sacrificial barrier that protects the steel

under the zinc, very similar to anodes provided in modern marine engines. The environment in which the trailer is used, stored and main-

tained determines the level of deterioration of the zinc. In areas of high humidity, high salinity or poor water quality, it is common for the

zinc finish to deteriorate very quickly, and a higher level of care is required to slow the deterioration of the zinc.

Trailers must be washed thoroughly after use with fresh water and must be dry before putting into storage in a garage or a well

ventilated area. This particularly applies to high temperature and humidity area's where the garage temperature will exceed 50 deg with

the garage doors closed. This accelerates the deterioration of the galvanized surface. It is most probable that salt residues will also drop

onto your trailer from the hull above whilst in storage. If this occurs, please wash as soon as practical to prevent the salt chlorides from

reacting with the zinc surface whilst drying.

It is normal as the zinc surface ages, that a white powder formation be evident on the galvanized components. This is normal excretion

from the zinc, called a calcium carbonate that forms as a layer over the zinc to protect itself from the elements. This is normally evident in

the low drainage points of the trailer, where salt residues collect. If this cosmetic only build-up is worrying it can be removed with a wire

brush, but is recommended that for maximum protection to be left alone. By regularly maintaining the galvanized surface of your trailer the

life of the zinc coating can be enhanced for many years. Cosmetic appearance of the galvanized surface is not covered by warranty
