HOT DIP GALVANISING Advantages
- Competitive First Cost
As a highly mechanised, closely controlled process, Hot Dip Galvanising can be carried out very economically in large batches. The alternative - painting - is highly labour intensive.
- Lowest Lifetime Cost
Low initial cost and long life make Hot Dip Galvanising the most versatile and economic way of protecting steel for long periods (25 + years).
- Long Life
Hot Dip Galvanising has many years proven performance. Long life up to seventy years is commonplace in most atmospheres. For more details see the Millennium Map Project.
- 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.
- Speed of Application
A fully galvanised protective coating can be applied in a few hours. A proper four coat paint system requires approximately one week.
- 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.
- Coating Toughness
Hot Dip Galvanising is unique - the coating bonds metallurgically with the steel giving a much greater resistance to damage than other coatings.
- Three Way Protection
Hot Dip Galvanising 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.
- Ease of Inspection
Hot Dip Galvanising 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).
- Faster Construction
Hot Dip Galvanised 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.
