The life of paint, powder  and other coatings applied to the surface of steel depends largely on how the surface of the steel has been prepared initially.


It essential that all mill scale, rust and previous coatings have been totally removed prior to painting and coating so that the new coatings are able to adhere to the steel. Coating over anything other than a bare white metal surface will lead to premature failure of the coating – rectification will be expensive as the coatings will have to be removed, the steel surface prepared properly and new coatings applied. If the steel has to be dismantled and removed from site then the cost of rectification will be out of all proportion to the initial cost of the project.

Shot blasting will ensure that the steel is cleaned to bare white metal, SA2.5 / SA3, giving the best possible surface essential for the application of paint, powder and other coatings.


We have various methods of shotblasting, which we apply as appropriate to the job. Shotblasting is appropriate for blasting ferrous metals and we blast using fine steel grits and ball shot to give a clean uniform finish.


With manual blastcleaning facilities with blastrooms 7.5m L x 3.5m W for large items and hand cabinets for smaller items a wide variety of projects can be undertaken

Large Fabrication shotblasted to SA3

We also have a range of automatic machines for high volume smaller components. The range includes:
Automatic ‘Tumblast’ rubber belt machine for small components
Automatic ‘Centri blast’ barrel blasting machine for larger batch blasting e.g. castings

Turbo charger castings cleaned by automatic centriblast operation

All blast cleaning is to the industry standard, SA2.5 and SA3 Swedish standards. For our fact sheet covering all Blast Cleaning Standards and cross reference to other standards please use the Contact Button and request a copy of Blast Cleaning Standards.

All work can be carried out to customers’ Ra (roughness average) specification and maintained by digital measurement.
