Bead Blasting and More
Prior to chemical finishing we can bead blast your aluminium parts up to 400mm x 300mm x 200mm. We use dry glass micro beads to remove minor machining marks, burrs and to present a more uniform finish. We also offer bead blasting without further chemical finishes.
Other specialist finishes such as hard anodise, hard chrome, matt chrome and zinc plate can be arranged with our partners across the UK.
Samples can be arranged by request.
