Arrow Starline Galvanised Steel Drywall Edge Bead 3000mm x 12.5mm (Pack of 50) - BEEB12

Plasterboard Edge Bead is used to reinforce plasterboard edges by enclosing them in a protective steel enclosure.

It is reversible therefore can be used with thin coat plaster or drylining paper tape.

Available in three sizes for varying thickness of plasterboard depth - 9.5, 12.5 and 15mm.

Application:

• The installation of Arrow beads should be in accordance with BS 5492:1990 (internal) and BS 5492:1991 (external)
• The most appropriate Arrow bead should be chosen to suit the application, required plaster/render depth and desired finish
• Beads should be fixed using plaster dabs or mechanical fixings at a maximum of 600mm intervals
• Beads can also be fixed to lathe sheets by the use of galvanised or stainless steel tye wire
• Use tinsnips to cut the bead wings and a fine-toothed saw to cut the nosing
• Care should be taken to ensure that steel beads are kept dry, and stored and handled in a way to prevent distortion and general damage, especially to the galvanised coating
• This means storing them off the ground on a flat surface
• The risk of corrosion in galvanised beads will normally only become apparent during the initial drying out period of the plaster, which should be kept to an absolute minimum (maximum 5-7 days), and subsequently during periods of heavy condensation and dampness
• All metal components used in a particular installation must be of all the same material type, i.e. stainless fixings with stainless beads/sheets and galvanised fixings for galvanised bead/sheets
  In external applications and in conditions where heavy condensation, persistent damp or regular exposure to moisture are likely, stainless steel or PVC-U beads must be used
• Stainless steel beads are for use with cement-based renders and not for use with gypsum based plasters unless they are specified with an approved protective finish
