Shot blasting / shot peening

Abrasive blast cleaning is by far the best method of surface preparation and in the long term, the most economical.

The purpose of blasting steel is to clean the substrate and produce a surface profile (anchor pattern). This is the etched surface produced when the abrasive strikes the metal. The surface profile allows modern corrosion prevention coatings to adhere. Corrosion prevention is less costly than replacement of a structure.

Blasting is the surest, most cost effective way to remove foreign matter and provide the right surface profile.

Shot for peening must be spherical, but can be made from cast steel, cut-wire, stainless steel, glass, ceramic and other materials. As each particle of shot strikes the metal surface, it produces a rounded indention. The primary reason for shot peening is to generate an even compressive stress pattern and to eliminate microscopic defects in the surface of the parts.

Shot peening improves the permissible stress levels for various material and, therefore, improves cycle service life.

There are thousands of applications for blasting with abrasives and utilizing peening media. Blasting and peening can be a solution anywhere there is a need to

• Prepare a surface for coatings
• Remove coatings from a surface
• Etch all or part of a surface
• Remove contaminants from a surface
• Remove rust, scale or other forms of oxidation
• Peen a surface to increase strength
• Remove flashing, burrs, welding burns or other unwanted markings from other construction or manufacturing processes
• Create uniform appearance
• Blend tool marks and scratches
