This way, we ensure from the outset that you have the ideal sia product to hand for any specific sanding application.

Surface analyses

Surface analysis

No two surfaces are the same. We analyse your surface quality requirements as a whole, taking into account your processing steps both upstream and downstream of the abrasive process. We optimise your working process to maximise productivity and efficiency and, if necessary, look for alternative treatment methods.
