However, for external use the finish should also be smooth, but it also needs to be a good paint system. This includes cleaning the metal from contamination, pre-treating it, so that under paint corrosion is slowed, and applying the right type of paint with enough thickness to produce a waterproof barrier. Where it's situated.
The more hostile the environment i.e. by the sea, or in a swimming pool, the more the paint system is going to be stressed. The Quality of the paint.

The pigments can be poor which can lead to the colour fading. How well it is maintained.If a polished steel tube is fitted on the beach with no paint or corrosion inhibiting compounds, and left, it will rust. If it is used it is cleaned and polished every day by the rubbing of hands, it will remain a polished steel tube. Therefore, a poor paint system will remain sound if it is cleaned enough. This is why all warranties require a cleaning schedule. |
