The 3mm Galvanised Thin Coat Angle Bead 3m is a plastering accessory made from corrosion-resistant galvanised steel, designed to produce neat, reinforced internal corners for thin-coat plaster and skim finish applications. Its 3 mm profile and perforated wings help the plaster key into the bead, creating a straight, crisp edge while reducing the risk of cracking and chipping at vulnerable wall junctions. Suitable for use on plasterboard, smooth blockwork and other drylining backgrounds, this angle bead supports professional-quality internal plaster finishes in residential and commercial build projects.
