ABRSASIVE BLASTING & SURFACE PREPARATION



Abrasive blasting is the industry standard of preparing surfaces in order to receive a coating application. Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.



This method allows the blasting technician to remove surface contaminants, mill scale, rust and already applied coatings from the substrate, ensuring a new clean surface on which a new coating can be applied which then creates a mechanical bond with the substrate.



The industry standards for substrate cleanliness are as follows;


SSPC SP5 / NACE # 1 White Metal Blast

SSPC SP10 / NACE # 2 Near White Blast

SSPC SP6 / NACE # 3 Commercial Blast

SSPC SP14 / NACE # 8 Industrial Blast

SSPC SP7 / NACE # 4 Brush Blast



IRON COATINGS FACILITY



Over our years of servicing many sectors and different industries we have blasted a diverse variety of equipment, structures and piping. With our strict adherence to specifications we are sure our product is of the highest quality, ensuring longevity of the coating product.



We are fully equipped to handle any blasting project, we have a 80 x 60 foot lit blasting building, many rotary screw air compressors running for 210 - 1600 CFM with blast pots and hoses, plus 2 x 40 ton blast media silos with direct feed to the blast pots. We also have many racks, skids and dolly's to move projects around, lessening the handling of your equipment or steel.



ABRASIVE MEDIA & SPECIFICATIONS



The abrasive used varies based on the surface treatment required. Common abrasives used include:

  • steel shot
  • steel grit
  • glass bead
  • crushed glass
  • aluminum oxide
  • silicon carbide
  • plastic
  • walnut shell
  • corn cob
  • baking soda
  • ceramic grit
  • copper slag



Media selection is a crucial decision in the engineering of abrasive blasting processes. The different media types have different hardness, shape, and density, and each is available in a wide range of particle sizes. Iron Coatings can happily accommodate any specification our clients require for their specific needs.
