Galvanised vs Stainless Steel
Explore the key differences between galvanised and stainless steel boat trailers, including corrosion resistance, durability, maintenance and cost. This guide explains why SBS Trailers use galvanised steel and how it compares to stainless.
Galvanised Steel
Corrosion Resistance
Galvanised steel offers excellent corrosion resistance, making it a trusted choice for boat trailers used in both freshwater and saltwater environments. The hot-dip galvanising process coats the steel in a protective layer of zinc, which shields it from moisture and oxygen, helping to prevent rust and extend the life of your trailer.
Durability & Strength
Known for its strength and reliability, galvanised steel provides a robust structure capable of handling heavy loads and regular use. The protective zinc coating also adds an extra layer of toughness, helping the trailer withstand knocks, abrasions and the demands of frequent launching and recovery.
Maintenance & Cost
One of the key advantages of galvanised steel trailers is their low maintenance. The zinc coating naturally protects the steel over time, reducing the need for ongoing treatments or repairs. Combined with a more cost-effective production process, galvanised steel offers excellent long-term value, making it a popular and practical choice for boat owners.
Stainless Steel
Corrosion Resistance
Stainless steel provides strong corrosion resistance thanks to its chromium content, which forms a protective barrier against moisture and oxidation. It performs well in marine environments, particularly in freshwater or occasional saltwater use, although prolonged exposure to saltwater without proper care can lead to surface corrosion over time.
Durability & Strength
Known for its clean finish and solid construction, stainless steel offers good strength and structural integrity. It resists everyday wear and maintains its appearance well, making it a popular choice where aesthetics are important. However, it can be more prone to surface marking and stress fatigue compared to galvanised steel in heavy-use trailer applications.
Maintenance & Cost
Stainless steel trailers typically require regular cleaning and maintenance to preserve their corrosion resistance, especially after saltwater use. While they offer a polished, premium look, they often come with a higher upfront cost and can be more expensive to repair, making long-term ownership costs an important consideration.
