Steel grit
High Carbon Steel Shot & Grit
Airblast-Abrasives B.V. has its own production line for high quality steelgrit with an excellent durability. In our warehouse in Holland we keep a stock of more than 750 tons of steel shot and steel grit.
Steel grit is a very cost economic blasting media in shot blasting machines and blast rooms, because it can be recycled many times. There are three different hardness’, steel grit GP, steel grit GL and steel grit GH.
Steel grit blasting in surface preparation is used for cleaning rust, old coating layers and creating an anchor profile for the coating system to adhere. Steel grit blasting media are also used to remove mill scale and in the foundry industry for removal of the sand from the work pieces.

Steel grit Applications
At Airblast, we have different sizes steel grit, depending on the application. For sand removal of large sized castings and scale removal of large sized products from forging, stamping, dieforging, drawing and rolling or after heat treatment (e.g. pipes, sections, plates, fittings, wire), we recommend the Steel grit G10/SG2.5 or the G12/SG2.0
The G16/SG1.4 and the G14/SG1.7 is used for sand removal of large and medium sized castings, scale removal of forging and heat-treated
work pieces, surface blast cleaning of steel plates, sections and steel structures, shot peening of work pieces or cutting of granite.
If you need surface blasting for smaller objects, we recommend the G25/SG1.0 or G40/SG0.7. For a full range of our sizes and applications, take a look at our data sheet or at the table below.
