Cleanliness level as a quality standard
For the degree of cleanliness, we use the Swedish standard as a gauge: SA1, SA2, SA2.5 or SA3, whereby the type of coating that will be applied determines which is required. The higher the grade, the cleaner the material. Of course, we radiate under regulated conditions.
Materials that can be blasted at Kalfsvel Coating include;
- Stainless Steel
- Hot-dip galvanized steel
We work with an inert blasting agent (aluminium oxide) and have two blasting cabins available with the following dimensions respectively: 22 x 7 x 5 meters and 8 x 4.4 x 4 meters.
Corundum blasting (grit blasting or steel blasting; not performed by Kalfsvel Coating) is a surface treatment of hard materials, whereby corundum grains (grit grains or steel grains) are blown against an object with the help of our powerful compressor and compressed air, in order to achieve the best abrasive effect with the aim of fully cleaning your product of contaminants. (rust, paint residues, oils, fats and / or other contaminants) and lay the foundation for an optimal bonding structure for further surface treatment.
