Galvanized Steel Rib Lath Mesh with 4–20 mm Rib Depth for Plaster Bonding

Steel rib lath, also known as expanded ribbed lath, is manufactured by punching and profiling galvanized steel sheet or stainless steel sheet. Its V-shaped ribs provide added stiffness and support, helping to maintain a uniform plastering depth across large areas.

The open mesh structure allows plaster to key through the lath for a secure bond. Steel rib lath is used as a plaster base on walls and suspended ceilings in building construction.
