1/4" self-furring v-groove Expanded Steel Plaster or Stucco Base

Self-Furring V-Groove Metal Lath is manufactured with five, approximately 1/4" deep, embossed “V” ribs, spaced 6" on center along the length of the sheet. The V’s allow thorough embedment into and behind the lath for superior mechanical bonding. A self-furring expanded V-Grooved metal lath, ideal for interior and exterior use over masonry, sheathing, and other solid surfaces as required per ASTM C847, ASTM C1780, ASTM C1063.

Description

The V-grooved self-furring plaster base is manufactured with evenly spaced indentations, 6" apart which run the length of the lath sheet holding the metal lath a consistent 1/4" away from the surface to be plastered.

The V-groove provides an ideal point of attachment of the fastener to achieve ASTM C1063 compliance. V-grooved metal lath is available with or without a Grade-D asphalt paper-backing, weather resistant barrier.
