There are various advantages of Hot Dip Galvanizing, a few among them are given below:

1. Competitive First Cost – As a highly mechanised, closely controlled process, Hot Dip
Galvanizing can be carried out very economically in large batches. The alternative –
painting – is highly labour intensive.

2. Lowest Lifetime Cost – Low initial cost and long life make Hot Dip Galvanizing the most
versatile and economic way of protecting steel for long periods (25 + years).

3. Long Life – Hot Dip Galvanizing has many years proven performance. Long life up to
seventy years is commonplace in most atmospheres.

4. Reliability – The process is simple, straightforward and closely controlled. The coating
thicknesses are regular, predictable and easily specified and are defined by I.S. EN ISO
1461 : 2009.

5. Speed of Application – A fully galvanized protective coating can be applied in a few hours. A
proper four coat paint system requires approximately one week.

6. Complete Coverage – Because it is dipped in molten zinc, all parts of the surfaces are
coated – inside and out – including awkward corners and narrow gaps.

7. Coating Toughness – Hot Dip Galvanizing is unique – the coating bonds metallurgically with
the steel giving a much greater resistance to damage than other coatings.

8. Three Way Protection – Hot Dip Galvanizing protects in three ways.
a) It weathers at a slow rate giving a long and predictable life.
b) The coating sacrifices itself to any small areas exposed through drilling, cutting or
accidental damage.
c) If large areas get damaged it prevents the sideways creep of rust.

9. Ease of Inspection – Hot Dip Galvanizing is an honest coating – if it looks continuous and
sound, it is so. Coating thickness can be checked easily with the use of a magnetic
probe (Elcometer).

10. Faster Construction – Hot Dip Galvanized steel is ready for use. No further site preparation,
painting or inspection is necessary. Once erected, cladding can begin immediately, thus
accelerating the construction programme.
