Steel shot is a metallic abrasive widely used for surface cleaning and surface hardening. Its round shape and high density apply a controlled impact to the surface, providing both cleaning and mechanical surface improvement. It is preferred especially in turbine blasting systems.

Blasting applications
- Removal of rust, paint and oxide layers
- Surface hardening (shot peening)
- Surface preparation before welding and coating
- Cleaning of cast and forged parts
- Surface treatment in the automotive, defence and shipbuilding industries
- Roughening of marble and stone surfaces
Advantages
- Provides effective cleaning and hardening with high impact power
- Its round shape allows processing without damaging the surface
- Long-lasting and reusable
- Offers a clean working environment with low dust generation
- Compatible with turbine and pressure systems
Steel shot offers superior performance in blasting for both cleaning and surface improvement. With its long service life, low dust generation and high impact power, it is an indispensable abrasive in industrial surface treatment.
