Benefit of Galvanizing.
1 – Long life
Galvanizing provides an easy to clean surface which can give a maintenance-free life of over 80 years and can be used in the hardest environments
2 – Competitive first cost
For many applications the cost of hot dip galvanizing is lower than applying Paint or composite coatings. The reason is simple: alternatives – particularly painting – are very labour intensive compared with galvanizing which is a highly mechanized, closely controlled factory process.
3 – Lowest lifetime cost
There are bonuses from no maintenance or extended maintenance intervals: fewer problems of access in remote areas, difficult terrain; also when there are safety restrictions (e.g. high-voltage electrical networks 500KV).
4 – Speed of application
A full protection coating can be applied in hours; a complicated paint system can require a week.
5 – Complete coverage
Because it is formed by dipping steel in molten zinc, all parts of the surface of the steel are coated – inside, outside, awkward corners, and narrow gaps
