On some occasions it may be necessary to shot blast steel prior to the galvanizing process. The following are examples of when shot blasting may be required.
- Heavily rusted steel has been used in a fabrication
- The material is being refurbished and old paint layers need to be removed
- Red oxide paint or shellac coated steel has been used in fabrication
Shot blasting is available at both Cumbernauld and Elgin sites at a competitive hourly rate. Blasting is carried out to SA 2.5, this ensures that all rust, mill scale and foreign particles are removed. If material needs to be blasted we will ensure that customer is informed before the job is started.
We do not advise galvanizing cast iron as the heat can lead to cracking and certain cast irons are soluble at this temperature. We can however blast the items and offer a 2 coat powder system which combines a zinc rich base coat and a polyester top coat.
If items need to be altered or have an existing part galvanized coating it may be necessary to strip the zinc prior to re-galvanizing. This service is available at both sites at an additional premium based on tonnage. Please contact us for information on pricing.
