Galvanising: the results
The appearance of finished galvanised coatings can differ according to the chemical composition of the steel substrate being used.

The final effect can range from bright and shiny to a dull grey colour, the latter caused by steel containing high silicon levels.

However, the high level of protection afforded by our galvanising coatings remains the same, regardless of their outward colour: the process will safeguard mild steel against corrosion in an external UK environment for between 40 to 70 years, and for over 100 years in indoor locations. However, there may be micro-climatic conditions that reduce this life expectancy, although these are the exception to the rule.
