Advantages

Advantages of Hot Dip Galvanizing

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. For more details see the Millennium Map Project.
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 : 1999.
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.
   • It weathers at a slow rate giving a long and predictable life.
   • The coating sacrifices itself to any small areas exposed through drilling, cutting or accidental damage.
   • 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.
