Steel Cleaning

Stainless Steels - Several finishes can be achieved on stainless steel by applying the blast cleaning process using various grades of glass bead, at varying pressures.  The glass bead removes the weld discolouration and leaves a satin finish. One of our regular customers manufactures weighing machines for the food industry and these have to have a clinically clean finish to meet food hygiene standards.  

About Corrosive Salts - Wrought iron and cast iron are course grainy metals and comparatively porous structures, which allow moisture and corrosive salts to get deeper into the surface of the metal than with say steel. When blasting them, they blast clean and look great - for a while - but the surface soon starts to oxidise (rust). This is because invisible salts are in the surface of the metal where the blasting can't reach them.  We take the item outside and hose it down with water and the rust forms almost before your eyes, then we blast it again, and until we are happy the salts are gone. Our phosphate treatment helps to stabilise and protect the surface until it is painted.
