Unplasticized polyvinyl chloride (PVC-U) corner, arch, edge and architrave beads for dry lining, drywall and skim plastering applications.

Corner beads (CB2) provide a clean edge and impact protection on external corners. Arch beads (CB2A) create smooth curves in arched reveals. Edge beads (EB0, EB12 and EB15) provide a clean end to plasterboard where it meets another finish such as a brick wall or door frame, and prevents cracking. Architrave beads (SGL20 and SGU15) provide a shadow gap between the wall and ceilings, skirting boards and door frames.
