Expamet Lathing provides an excellent key for finishing materials on masonry, ceilings, suspended ceilings and timber frame buildings. Suitable for internal or external applications, it is easily formed, allowing designers to create free forms such as arches, domes and vaults in a trouble-free manner. Can also be used as a carrier for fire protection finishes to structural steelwork.

Metal laths are formed in either galvanized or stainless steel and are produced in three main forms:

  • Diamond patterned mesh (Expanded Metal Lathing).
  • Herringbone-patterned mesh with V-profiled ribs (Riblath).
  • Ribbed mesh with tangs (Hy-Rib).
