Galvanizing our metal structures - recommended but Optional
How much it will cost?
Hot dip galvanizing is often perceived to be more expensive than it is. There are two reasons for this: Firstly, that such a high performance coating is automatically assumed to be expensive. Secondly, the initial cost of galvanising relative to paint has changed significantly over recent years. Painting costs have steadily increased whilst galvanising costs have remained stable.
Longevity
In the vast majority of cases galvanizing provides a maintenance-free life of over 40 years, environment dependant. The coating weathers at a very slow rate giving a long and predictable life, usually around 1 to 1.5 microns per year throughout most of the country

Competitive first cost
Painting steelwork can be highly labour intensive whereas galvanizing is relatively low.
Compared to many applications the cost of galvanizing is lower than that of applying an alternative coating. |
Lowest Lifetime costs
The low initial cost and longevity of hot dip galvanizing, makes this corrosion protection system the most versatile and economic way of protecting steel for long periods.

Coating ToughnessWhen material is hot dip galvanized the zinc is bonded metallurgically to the steel, it becomes part of the structure,as a result galvanized steel is far likely to be effected by mechanical damage during handling, storage, transport and construction.
|
COMPLETE COVERAGE
Unlike painted systems, hot dip galvanizing ensures all parts of the surface of the steel are coated.
|
Sandblasting
When metal structures are for galvanizing that might be contaminated with paint or grease, and the only way to remove this would be to shotblast the material. The contaminants need to be removed prior to galvanizing because it prevents the steel being pickled by the acid, if material isn’t acid pickled correctly then galvanizing will not take place.
