Pickling The steel profiles are immersed in a hydrochloric acid bath. We call this pickling. This is necessary to make the surface free of dirt and grease before a profile is coated or post-galvanized, so that good adhesion can be guaranteed. Rays and minds An excellent method to improve adhesion is blasting profiles. Blasting is chosen when, for example, the profile is welded or when the surface must be free of mill scale. The surface of the profile is blasted with sand (grid) under high pressure. This removes all grease and mill scale from the profile. An additional advantage is that the surface of the profile is roughened by blasting, so that the coating adheres better. After sandblasting, the profiles are provided with a red or gray lead (a kind of primer that forms an excellent protection and adhesion layer). Then the profiles are ready to be treated. Coating The (powder) coating of profiles means that the profiles are provided with a sprayed (powder) coating in any desired color. This process can be applied to profiles that come into view, for example with warehouse racks. Hot dip galvanizing Iron and steel rust. The oxide layer that is formed on steel has a larger volume than the steel itself and therefore does not form a protective barrier layer. For many steel applications it is therefore necessary to protect the product against rusting. With hot dip galvanizing, the profiles are first immersed in a hydrochloric acid bath; we call this pickling. Then the profiles are placed in a bath with liquid zinc. It is therefore also called hot dip galvanizing. The zinc layer depends on the thickness of the material to be galvanized. Trend: magnesium / zinc coating replaces hot-dip galvanizing In recent years we increasingly use a steel quality with a magnesium / zinc coating. It is no less than 10 times more resistant to corrosion than galvanized steel, even in the most demanding outdoor environments. We are happy to tell you more about the possibilities and the financial savings.
