The key to high quality paint finish is the preparation, if the steel hasn’t been properly prepared no amount of paint will give you a quality long lasting finish.

Radleigh-Nash carry out blast cleaning to both ferrous and non-ferrous fabrications using chilled iron grit and aluminium oxide respectively. The process of blast cleaning is used for the preparation of the substrate to remove mill-scale and oxides, and to provide a key prior to the application of paint, thermal spray or galvanizing, where a heavier deposit of zinc is required. It also highlights faults in welds, such as pinholes, that are not visible before the blast cleaning takes place.

Our Wolverhampton site benefits from having 3 large blasting booths, all serviced by overhead cranes. Our largest booth is 13M in length x 6M wide x 6M high but can accommodate longer if needed. We can offer shot blasting of bare steel as well as blast cleaning of already painted parts to suit customer needs. From a blasting a large vessel for a multi coat paint system or blast only with palletising and wrapping of small components and everything in-between we are happy to help.

We can have a dedicated non-ferrous (aluminium, brass, copper…) both, using an aluminium oxide/bauxite abrasive. This booth is 7M in length x 3M wide x 3M high and is serviced by our 8 ton over head crane. For special projects requiring larger facilities we can clean down one of our larger blast rooms and change the medium over to suit customer requirements.

Shot Blasting Service

The requirements for blast cleaning are extensively covered in BS 7079 Parts 0 - 6, together with ISO 8501 - 8504. The detail laid down in these standards is exhaustive and includes preparation methods and grades of preparation which are depicted by photographic/Surface Comparator Chart examples to SA1, SA2, SA2.5 and SA3 introduced by the Swedish Institute of Corrosion in SIS 05 5900 and now incorporated into ISO 8501-1.
