Steel shot is a spherical medium made from annealed, or heat treated, high-carbon steel. An extremely durable and dense medium, it is characterised by its optimum resistance to fatigue and fracture. Steel shot retains its shape during use and is ideal for peening applications. The result of this durability is an efficient and economical abrasive product. Supplied in a range of grades, shot can be used in the majority of airless blast applications.
Applications: sand, rust and paint removal, peening, descaling, deflashing, cleaning and pre-coat surface preparation.
Suitable for: ferrous and non ferrous metals; natural stone and concrete; structural steel plates and fabrications; castings & forgings; heat treated components.

Steel grit is an angular medium produced by crushing heat treated spherical steel shot pellets. Grit is tougher and more aggressive than steel shot and is available in three different hardness specifications; GN, GL and GH. GN and GL are both suitable for airless and air blast applications and will round off during use, whereas GH will retain its angular shape. GH is the hardest of the 3 grades, is resistant to shattering and is suitable for airblast applications.
Applications: pre-coat surface preparation, sand and rust removal, descaling, etching, cleaning, gang-saw stone cutting.
Suitable for: foundry applications; structural steel plates, profiles & fabrications; heat treated components; mill rolls; ferrous and non-ferrous forgings & castings; stone surface texturing.

AMACAST-Stainless steel shot is the most cost effective stainless steel medium due its hardness and longer life. At a minimum density 7 g/cc, AMACAST is denser than any other stainless steel shot on the market, translating to delivery of more cleaning energy per cm2 to the work surface. This resluts in improved rate of cleaning, thereby lowering production costs and blast time requirements. In addition, AMACAST's superior durability provides consistent distribution by remaining in the work-mix long after other abrasives have fructured and been removed.
Applications: surface preparation, cleaning, peening, deburring, descaling, sand, rust & paint removal.
Suitable for: automotive; aerospace; construction; mining; agriculture and foundry industries.

Chilled iron grit is a white iron structure which is produced from carefully selected re-carbonised iron scrap and then crashed into grit. It is an aggressive abrasive medium which shatters on impact rather than wearing round. Chilled iron grit is harder than steel and it cleans at quicker rates. Due to its hardness and performance speed, it is most commonly used in air driven machines to etch structural steel and components prior to paint, metal spray or plastic coating.
Applications: cleaning, stripping, descaling, surface preparation, etching, sand and rust removal and gang-saw stone cutting.
Suitable for: hard components; steel mill rolls; steel profiles and fabrications; steel castings and forgings.

Cut wire is an aggressive abrasive medium which is available in two forms: Standard (SCW) for blast cleaning and Conditioned (CCW) for peening. The pellets are made from drawn wire cut to a length; equivalent to the wire diameter. Being drawn rather than cast means that it is stronger than shot and has a longer working life. The more aggressive SCW pellet comes rated as either medium or high tensile in sizes of 0.3 – 2.5 mm diameter. It is used for quick removal of surface contaminants and has application in foundry and construction industries for de-sanding, cleaning and scale-removal. The term “conditioning” refers to the process whereby the pellets of wire are rounded off to create a solid near spherical shape. This makes CCW pellets ideal for peening where consistency in media particle size, hardness and density is required throughout the peeing process. Pellet sizes of 0.3 – 1.4 mm are available in three levels of conditioning.
Applications: peening, descaling, cleaning and deburring.
Suitable for: ferrous metal, steel castings & forgings, concrete & natural stone and aluminium & zinc diecastings.

Garnet is a strong, hard and durable abrasive medium, making it a low dust and cost effective alternative to some other media. The particles are dense with sharp cutting edges, both of which assist in producing a very clean finish. Garnet can be used in place of silica sand, mineral slag and steel grit. W.Granowski can guarantee product supply of minimum 99% garnet with no silica or heavy metal content and, through a rigorous washing process, a level of chloride lower than the International Standard. Granowski garnet comes in three mesh sizes 20/40, 30/60, and 50/80, and depending upon the application, can achieve 4 – 7 passes.
Application: pre-coat surface treatment, water-jet cutting, cleaning, blasting, rust removal, and stripping.
Suitable for: most metal surfaces; wood; plastic; rubber; glass; natural stone and concrete; turbine blades; fibreglass hulls.

Plastic media are designed for specific applications and are mainly used for removing/stripping coatings from surfaces, thereby eliminating the need for solvent use. Depending on the product selected, plastic media can be used where an abrasive function is required and can also be used in non-abrasive applications. They are also commonly used for deflashing lighter components where heavier media could damage the parts being cleaned.
Application: deflashing, coating removal/stripping, cleaning of machinery, marine vessels and aircraft frames.
Suitable for: soft metals; thin aluminium; engineered plastics; fibreglass; a variety of electric componentry; injection mouldings; stainless and mild steel sheeting; thermoset moulded parts.

Glass bead is used in all types of compressed air blast equipment, using a dry or wet process. Surface treatment with glass bead can be used as a finishing process or as a supplement treatment. For example, initial treatment utilising aluminium oxide followed by glass bead greatly improves the surface finish, leaving a satin lustre. Glass bead is a relatively gentle surface treatment which makes it ideal for use on delicate and precision parts as it won’t distort dimensions and results in a smooth polished surface.
Applications: deburring, finishing, pre-coat surface treatment, descaling, removal of carbon, paint and corrosion deposits, polishing, etching, removal of residual deposits from moulds, peening.
Suitable for: delicate aluminium mouldings & castings; pump and meter reconditioning; plastic, glass and rubber mouldings; instrument & electrical parts; bearings, gears & precision parts; finishing non metallic decorative pieces.

Applications: surface preparation, cleaning, preparing parts for metallising, plating & welding, descaling
Suitable for: cylinder heads, valves and pistons in the automotive industry; turbine blades in the aircraft industry; ferrous and non-ferrous metal components.

Applications: pre coat surface preparation, stripping, cleaning, blasting, surface preparation and rust removal
Suitable for: plastic; glass; rubber; metal components; fibreglass; natural stone & concrete; ceramic surfaces.
