Surface preparation

Tunnel and Blast Room Blasting

Surface preparation to ISO 8501-1 with the largest-inlet tunnel shot blaster built in Türkiye and 14-metre blast rooms.

What is abrasive blasting and why is it needed?

Steel rusts when exposed to moisture and air. Abrasive blasting removes oil, dirt, rust, mill scale and old paint from the metal surface with certified abrasives and creates the surface profile the coating needs to adhere.

Properly executed blasting directly determines the life of the coating system and therefore of the steel. We create the surface profile to the targeted micron depth in accordance with ISO 8503-2 and verify it with a digital profile gauge.

Our blasting equipment

Surface cleanliness grades

The required grade depends on the coating manufacturer’s specification and the service environment. We blast to Sa 1, Sa 2, Sa 2½ and Sa 3.

GradeDefinitionSurface condition
Sa 1Light blast cleaningLoose mill scale, rust, paint and foreign matter are removed.
Sa 2Thorough blast cleaningMost mill scale, rust and paint are removed; any residue is firmly adherent.
Sa 2½Very thorough blast cleaningOnly slight stains or shadows may remain. The most frequently specified grade for industrial coating systems.
Sa 3Blast cleaning to visually clean steelThe surface is completely clean with a uniform metallic colour; required for tank linings and heavy-duty coatings.

Blast rooms: parts up to 14 metres

Our two manual blast rooms measuring 5000 × 5000 × 14000 mm allow large and complex parts to be blasted in a controlled environment, independent of the weather. 15 overhead cranes handle heavy parts safely.

Steel sections prepared for the automatic tunnel blasting line

Automatic tunnel shot blasting

Our 18-turbine (3000 × 1800 mm) and 6-turbine (2000 × 1000 mm) tunnel machines blast sections, plates, pipes and structures at high speed with uniform, repeatable quality; shop primer can be applied to rolled sections and profiles.

Frequently asked questions

About abrasive blasting

What is abrasive blasting?

Abrasive blasting cleans oil, dirt, rust, mill scale and old paint from steel with abrasives propelled by blast wheels (turbines) or compressed air. It is carried out before painting and creates the surface profile the coating adheres to.

What is the difference between tunnel blasting and blast room blasting?

In tunnel (automatic) blasting, turbines throw the abrasive at the part while sections, plates and structures pass through on a conveyor, giving fast, uniform results. In a blast room an operator works with compressed air, which suits complex parts up to 14 metres long.

What does Sa 2½ mean?

Sa 2½ is the “very thorough blast cleaning” grade of ISO 8501-1. No mill scale, rust or paint remains; only slight shadows or stains are acceptable. It is the grade most industrial coating systems require.

Which abrasives do you use?

Steel shot, steel grit, silica, quartz, basalt and glass beads. The abrasive is chosen according to the material, the required cleanliness grade and the surface profile targeted under ISO 8503-2. All our abrasives are certified.

How soon after blasting should steel be painted?

Blasted steel starts to rust again quickly when exposed to moisture, so the primer should be applied as soon as possible. Blasting and painting in the same plant under measured ambient conditions is a major advantage.
