Glass microbreads

Glass microbeads are used to process stainless steel, aluminium and other non-ferrous metals; for polishing and dulling surface and for cleaning fragile items.
Glass microbreads
The Alumetal-Technik’s goal is a constant improvement in the abrasive blasting process. Our priorities are the safety of the operators, surface quality and cost optimization. Those are the main reasons why we started cooperation with the best European glass microbeads producers. The purpose of glass microbeads are polishing and smoothing the surface with a guarantee of high and repeatability quality. Glass shot are great material for processing the stainless steel, non-ferrous metals and its alloys and fragile elements.  

Properties of glass microbeads

Glass microbeads main properties are round shape, smooth surface and chemical inertness – it is safe for the operator because it does not contain the free crystalline silica. Glass shot is safe for processed elements as well – it is not contaminated with ferrous, so any chemical additions are not needed. If used properly, the microbeads can be used multiple times.  

Modern solution for abrasive cleaning – the glass shot

In our offer, you can find only the high quality, reusable and ecologic abrasive media. The secret of our microbeads is that it is made of high-quality material. The microbeads are packed in 25 kg bags.
