Garnet abrasives are used for industrial applications such as water jet cutting and abrasive blasting (sandblasting) for surface preparation, cleaning, descaling, and removing paint and rust from metal, concrete, and stone surfaces. Its high hardness, low dust production, and ability to maintain sharpness make it effective for preparing surfaces for coatings, profiling metal, cleaning historic structures, and ething concrete.

Abrasive Blasting
Surface Preparation:
Garnet abrasive removes contaminants like old paint, mill scale, and rust from surfaces like ship hulls, industrial tanks, and metal structures, preparing them for new coatings.
Cleaning & Descaling:
It's used for general cleaning and descaling of metal and concrete surfaces in various industrial settings.
Etching & Profiling:
The sharp edges of garnet are used to etch concrete, expose aggregates, and profile metal surfaces for better adhesion of coatings or welding.
Restoration:
Its effectiveness and gentleness on substrates make it ideal for cleaning historic buildings and monuments.
Water Jet Cutting
Cutting Various Materials:
Garnet is added to high-pressure water jets to cut through hard materials such as metal, stone, and ceramics with precision.
High-Performance Cutting:
The combination of garnet's hardness and the water jet's force creates a powerful, dust-free cutting stream for various industrial applications.
Why Garnet is Chosen
Hardness:
Its high hardness (7-8 on the Mohs scale) allows it to cut and clean surfaces efficiently.
Low Dust:
Unlike some other abrasives, garnet produces minimal dust, which is beneficial for worker safety and the environment.
Durability:
Garnet maintains its sharpness and form longer than softer abrasives, ensuring consistent performance and reducing replacement frequency.
Versatility:
It works effectively on a wide range of materials, including metal, concrete, and stone.
