Cast Stainless Steel Grit
GRITTAL is the economic alternative to mineral grit abrasives and fulfills all requirements concerning blasting performance and a corrosion-free surface finish.
GRITTAL offers clear economic and environmental advantages.
The extremely high durability of this rust-free stainless steel grit reduces the amount of abrasive consumption by a factor of 30 – 100 and thereby also minimizes the amount of waste that is generated.
The durability of GRITTAL results in a consistent work mix, constant roughness values and guarantees quality adhesion for subsequent coatings.
GRITTAL’s dust-free characteristic allows for excellent vision while blasting and helps to better control the blast process.
GRITTAL is successfully used in blast rooms and blast cabinets as well as in centrifugal wheel blast machines.
