SANDBLASTING


Sandblasting is a fast and efficient way of cleaning materials. When sandblasting, sand is blown across a product with high pressure. Because of the great power with which this happens, everything that is attached to the material gets removed. Especially for the cleaning of construction steel this method is used a lot to remove rust, scale and other coverings. Stainless steel and aluminium are also made ready for further treatment by sandblasting them. Wood can also be sandblasted; the surface then gets rougher.

Sweep blasting
When using less pressure and going only lightly over the material, this is called “sweep blasting”. This corresponds with the SA-quality standard SA1. Information about these quality standards can be found below. This method of blasting is especially suited for cleaning galvanized materials. Zinc salts and other pollution then get removed without damaging the zinc layer. Above that the surface gets roughened, which improves the attachment of the coating.

Sizes and quality standards
The cabin in which we sandblast is 4000 mm wide, 4000 mm high and 8000 mm long. The maximum weight of the objects we can handle is 2000 kilo.

You can choose how you want your material to be sandblasted (according to the SA-quality standards; SA 2,5 is taken as a standard):
SA 1: light blast cleaning; most rust, roll layers and other covers are removed.
Sa 2: Thorough blast-cleaning; practically all rust, roll layers and other covers are removed. The material now has a grey-like color.
Sa 2,5: Very thorough blast cleaning; everything is now removed and remains only to be seen as a light shadow. This is the standard way of sandblasting.
Sa 3: Blast cleaning to visually clean steel; even dust is now removed. The material now has an even color.
