Sand-Blasting is a surface preparation method mostly used in a number of different industries with a variety of project scopes. Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. A sandblasting setup usually consists of three different parts: the abrasive itself, an air compressor, and a blaster nozzle. The various material types have different characteristics namely, hardness, shape, and density, and each is available in a wide range of particle sizes.
Grade |
Size Range |
Profile* |
Application |
---|---|---|---|
1 |
0.1 – 0.4mm | Less than fine | Cleaning surfaces where low profile is required. Suitable for the restoration of classic cars and motor bikes |
2 |
0.2mm – 0.85mm | Fine | To provide a fine profile for low build paints, selective removal of coatings and wet blasting. Also suitable for small nozzle work and hand guns. |
3 |
0.2mm – 1.40mm | Medium | Specially graded to rapidly clean steelwork with a medium profile to suit the majority of industrial coatings. Suitable for ships hulls, tanks, storage vessel bridges and steel fabrications |
4 |
0.2mm – 1.70mm | Medium | Specially graded to rapidly clean steelwork with a medium profile to suit the majority of industrial coatings. Suitable for ships hulls, tanks, storage vessel bridges and steel fabrications |
5 |
0.5mm – 2.0mm | Coarse | To provide coarser profile suitable for metal spray. |
6 |
0.2mm – 2.50mm | Coarse | Highly corroded steel. |
7 |
0.5mm – 2.50mm | Coarse | Removal of heavy scale. To provide very coarse profile. |
