GG Finishing

Blasting, cleaning the unwanted particles and corrosion residues on the surface will ensure that the paint and coatings to be applied to the surface will last longer. At the same time, thanks to the roughening on the surface, it will ensure that the paint and coating adhere very well.

• Surface cleaning
• Removal of rust and corrasion residues
• Cleaning of paint residues
• Removing certain level scratches on the surface
• Surface roughening
• Surface preparation before coating and painting process

Whell blasting (Hanger blasting, Drum blasting, Continuous blasting), Pressure blasting (Continuous Blasting, Drum Blasting, Vacuum system blasting)

Many blasting granules available. The main of these;

• Steel Shot
• Steel Grit
• Stainless Steel Shot / Grit
• Shot/Grit
• Glass Beads
• Aluminum Oxide (Pink, Brown, White)
• Garnet
• Cut Wire Shot
• Plastic Abrasives
• Ceramic Beads

Thanks to its non-iron structure, the glass beads can be applied to any material as well as especially used in stainless steel, aluminium, copper, plastic and composite materials . ( plastic and composite ferrous materials non-ferrous metals) It is generally, used for decorative purposes and surface cleaning as its abrasive feature is partially low.

Blasting with aluminum oxide can be applied to any material. Thanks to its angular and hard structures it is suitable for roughening . It is one of the most suitable abrasives for pre-coating preparation .

Steel shot blasting is mostly used for non-stainless ferrous materials and non-rust metals. Steel grit on the other hand, is more suitable for use in cases, where surface cleaning and high roughness are required, such as paint removal, thanks to its angular structure. Blasting with steel granules, creates a minimum level of dust in the environment.

SA 1 : It's an extremely superficial degree of cleanliness. It is an extremely superficial form of cleaning on rusted surfaces and is called “Sweeping” in the market.

SA 2 : It is a blasting grade where the steel is very cleaned, and the surface is highly roughened.

SA 2,5 : It is most preferred blasting grade in the market where the steel surface is well roughened, almost all of the unwanted formations, are cleaned and the unique gray color of the steel can be seen easily.

SA 3 : It is a blasting degree where is the steel surface is roughened very well and the undesired formations are completely removed, and the distinctive gray color of the steel is completely revealed.

Shotpeening is a cold working process in which the surface fatique strenght is increased by creating compressive stress on the surface by spraying special materials on the surface part.

Shotpeening is a process in which the fatigue strength of the materials is increased, thereby maximizing the service life. Particularly applicable for moving and stressed parts.

The Shotpeening process is similar to the blasting process. However, the process parameters and the granule to be used play a critical role in the shotpeening process and for each different product.
