To achieve a clean, uniform, and durable surface, it is essential to remove all impurities – especially tarnishes at welding seams and cutting edges – and to re-establish the oxide layer.
The absolute best method to achieve this is immersion pickling, where the processed item is submerged in a tank with pickling solution. Between 1-8 hours, depending on the type of steel, the surface will be absolutely clean – everywhere.
Then the item is moved to a rinsing tank with water, and finally, a thorough high-pressure wash is carried out.
As an additional treatment, we offer the option of applying passivation solution or vegetable oil, which further improves the surface’s resistance.
Immersion pickling is performed in 2.5 x 3 x 10 immersion tanks tanks.
