Eli mikä on tehokkain ja varmin tapa saada maalit pois rungon sisältä ennen kuumagalvanointia.

Nyt otetaan vastaan kaikki vinkit.

Niin runko on LR Defender 90

Tassa olisi takalaiset ohjeet:

1. Soil and grease removal: A hot alkaline cleaner is usually used to remove oil, grease, shop oil, and soluble paints. This will not, however, remove such things as epoxies, vinyls, asphalt, or welding slag. These soils must be removed by grit blasting, or other mechanical cleaning which is normally not the responsibility of the galvanizer.
2. Pickling: An acid bath is used to remove surface rust and mill scale to provide a chemically clean metallic surface. Many galvanizers prefer the use of hydrochloric acid since it is more environmentally friendly and will not effect the surface of the steel which may be possible with the use of sulfuric acid.
