Solutions for your shot blast application
How abrasives are used in your shot blast applications
From creating profiles, removing sand from casting to reinforcing metal parts, abrasive media supports many shot blast applications.
To help categorized these shotblasting applications, we have grouped them into 5 different categories, which are: Cleaning, Preparation, Peening, Cutting and finally, miscellaneous applications requiring an abrasive media.
Cleaning is the process of desanding and descaling prior to further transformations used in foundries, forges, and mills.

Preparing is a treatment process that increases the adhesion to the surface in order to apply a coating: adhesive, paint, etc.
Discover more
Peening is the process of working the surface of a metal to improve its material properties, in our case mechanically, by shot blasting (also known as cold working process)
Discover more
Cutting is the name used to define the application of cutting blocks of granite and other hard stones with the use of Gang Saw machines.

Distinct: There are many other applications using various steel abrasive media, to name a few: ballast, radiation shielding, anti-slip additive, cored wire, incinerator and heat exchanger cleaning systems …
Discover moreWhat is abrasive blasting
Abrasive blasting refers to a high-pressure stream of shot or grit on surfaces to shape it or provide a texture such as rough or smooth. It’s mainly used in industry before painting, coating or just as finishing.
What is Shot blasting?
Blastwheel or compressed air...
It is the projection of an abrasive onto a surface, mechanically or using air or a fluid, to remove debris, enhance the product’s properties, and/or create the desired surface finish.
Here are the 2 main systems used to project the abrasive:
Compressed air blasting and water jet sandblasting:
The method involves moving an abrasive or a shot over a surface using air or water at very high pressure, through a hose. The fluids are air or water. Generally, this mixture is projected using a set of compressors, a blast pot, flexible hoses, and a nozzle (i.e.: Clemco, Empire, Schmidt, etc.). The main advantage of compressed air blasting is that it is a low-cost way to clean and prepare surfaces, in an industrial environment or outdoors. It also produces a concentrated blasting surface.
Turbine blasting:
The second method involves using a turbine blaster (also called wheel blat or Wheelabrator). It converts electrical energy from a motor into the abrasive’s kinetic energy, through the rotation of the impeller. Its main advantages are its speed, its ability to project a large volume of abrasive, its efficiency, and its ability to clean large parts.
Shot blasting application objectives
The applications are many and varied, and these typical objectives are:
- Remove blemishes/rust/stains
- Thoroughly clean the metal parts
- Remove surface contaminants, including sand or scale
- Provide a specific surface profile for coating or finishing application
- Change surface properties including increased pre-stress
Ensuring a successful blasting operation
Many factors impact your steel surface preparation, such as the type of coating, abrasive or shot blasting technique. As experts for decades, we have developed technologies and methods to ensure minimal risk of coating failure– Change surface properties including increased pre-stress.
