Steel shot blasting

In performing its work, Proficolor s.r.o. complies with the provisions of valid norms. For blasting, it mainly complies with ČSN ISO 8501 and for application of coating it complies with ČSN ISO 12944. Surface treatment by blasting is performed by the dry blasting of the metal’s surface with pressurized air and a dry abrasive. The type of abrasive used is always recommended in accordance with the specific nature of the job and the requirements for cleanliness and roughness of the surface. For blasting in a fixed or mobile blasting unit, sharp edged steel filings are used as an abrasive, and various kinds of cinders or dried silicon sand are used for blasting of structures. Surface treatment by mechanical cleaning is performed using mechanical tools like brushes, rust chisels, grinders and grinding paper. Mechanical cleaning is performed where blasting of a surface is not possible or if a steel structure does not require a long service life coating.
