Preparation of the surface - shot-blasting

Preparation of the surface - shot-blasting

SHOT-BLASTING

High quality preparation of steel surface (cleaning) accomplished with shot-blasting. The procedure is performed using solid particles of shot blasted to the metal surface. Shot blast is performed in correspondence with international ISO 8501-1:1988 standard.

 

 

 

LEVELS OF SURFACE PREP

Sa 1
Light cleaning with shot-blasting
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint.
Sa 2
Proper cleaning with shot-blasting
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint. The rest of contamination needs to be strongly added to the surface
Sa 2,5
Very proper cleaning with shot-blasting
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint. All of the rests of contamination will appear as light blur and shadow
Sa 3
Cleaning with shot - blasting till the clean steel
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint. The surface needs to have one-faced color of the metal.

 

CLEANING WITH HAND AND MACHINE TOOL

Preparation of the surface with hand and machine cleaning as abrading, grinding with wire brush, machine grinding and milling

St 1 The level of cleaning is not applicable because that kind of surface is not adequate for application of paint
St 2
Proper hand and machine cleaning
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint.
St 3
Very proper hand and machine cleaning
Looked without a zoom, surface needs to be free of visible oil, grease or dirt, also of weakly corrosion and paint. Only the metal needs to get the glow that comes from metal base
