As well as powder coating, we also offer a shot blasting facility. Some shot blasting applications…
For pre-treatment of steel ready for powder coating
Shot blasting is our method of pre-treating steelwork that is to be powder coated only (not first hot dip galvanized). Shot blasting the steel surface both cleans and keys it in preparation for the powder coating process. Without shot blasting the adherence of the paint to the steel would be less effective.
For cleaning old steel
Shot blasting is also an excellent way of cleaning steelwork free of oil, grease and old or unwanted paint systems. It is usually the first step when customers wish to refurbish all types of old steelwork whether this is gates, railings, vehicle chassis, domestic radiators, etc.
For increasing a hot dip galvanized coating thickness
Our sister plants Shropshire Galvanizers and Hereford Galvanizers galvanize steel to BS EN ISO 1461 (2009) which dictates a certain zinc thickness. Hot dip galvanizing is an unrivalled coating system for protecting steelwork against environmental corrosion however, in some very extreme environments that require extended life to first maintenance systems shot blasting steelwork prior to galvanizing it can increase the galvanized coating thickness by up to 65%.
