What is hot dip galvanising?
Hot-dip galvanising is the process of immersion of steel fabricated components in molten zinc/alloy. One of the advantages of hot-dipping is that the coatings are much thicker and therefore much more corrosion resistant. Zinc coatings prevent oxidation of the protected metal by forming a barrier. This is a thick, tough metallic zinc envelope, which covers the steel surface and seals it extremely well from the corrosive action of harsh Australia environments, specially within coastal areas.
The thickness of a hot-dip galvanised coating is beneficial in providing long life, durability and performance. We favor hot-dip galvanising because of the extended maintenance-free service that it provides in protecting the trailer against corrosion. When compared to painting, hot-dip galvanising has similar initial application costs but almost always, lower life-cycle costs, thus making galvanising the smart choice for today and tomorrow. It is the best choice in terms of long term durability and cost effectiveness.
When going off road, you are bound to get scratches. Paint is a barrier protector only, and when scratches and cracks occur, corrosion of the underlying steel is immediate. Paint systems requires a lot of maintenance, partial repainting and full repainting several times. Over a 30-75 years life, the costs can be staggering, making the decision to painted models over galvanised ones could be a costly one in the long run.
