Shot blasting

Preparation of surfaces before painting or as a decorative finish

For stripping and preparing surfaces for subsequent coating, chilled iron grit is the usual choice.

By controlling the grade of the grit and the particle velocity used, both the cleanliness of the object and the profile of the surface can be varied.

For non-ferrous materials and stainless steel, aluminium oxide particles with different particle coarseness or 'mesh size' are used to give varying profiles.

Decorative finishes can be applied using glass beads which give an elegant satin finish to materials such as stainless steel, without the risk of ferrous contamination.
