Some call it metallisation while others call this post-treatment the Schoop proces or zinc spraying. At Ulamo, we usually speak of the Schoop proces, as the process was invented by the Swiss engineer Schoop in the early 20th century.
What is the Schoop process?
The purpose of the Schoop process is to make the metal more resistant to rust and oxidation. During the Schoop process, a high-quality and rust-resistant zinc layer is applied to the surface that has been pre-blasted. The Schoop process is performed with a flame, the corrosion-resistant metal zinc and a flame spray gun. The flame heats the zinc so that it becomes a liquid. The molten material is then deposited on the product surface to be protected. The molten zinc adheres to it as small spatters. As the process progresses, a dense layer is created that protects the material even better against corrosion.
Why use the Schoop process?
We advise using the Schoop process if your steel products that need to be powder-coated have an outdoor application. After blasting and applying the Schoop process, they usually receive a two-layer system. They are therefore extremely resistant even to conditions that are highly corrosive.
Maximum dimensions for the Schoop process
7.000 x 2.000 x 2.600 mm
The maximum capacity is limited when the maximum length, breadth or depth measurements are reached.
