Mega Lath

heavy duty Reinforcing

Mega Lath is a self-furring welded wire that provides heavy-duty reinforcing for both stucco and stone installation.

Application(s): Stone Veneer, Stucco

Mega Lath is an engineered product that provides easy attachment for both wood and steel construction. Specifically designed for stucco applications that require extra reinforcing, Mega Lath can be used as an alternative to 3.4 lb/yd2 diamond mesh metal lath specified in ASTM C847 and at 1.95 lb/yd2. Mega Lath can be installed 24" o.c. over open framing. Mega Lath is recommended wherever 2.5 lb/ydor 3.4 lb/yd2 metal sheet lath is specified.

Structa Wire products are sold by ClarkDietrich in markets East of the Rocky Mountains. For all inquiries in the Rocky Mountain region and Westward, please reach out to Structa Wire Corp. for service.


  • Mega Lath is made with less metal but has more strength than any other product available – including sheet lath products
  • It is engineered to meet weight requirements for architectural stone product installations



  • Dense product is made from 16ga X 17ga galvanized steel wire welded to form 11/16" x 1.5"  openings
  • Its design promotes uniform plaster thickness
  • A series of flat-bottomed V-shaped furrs ensure a full 3/8" scratch coat
  • Furr will not puncture the vapour barrier
  • Additional cold-rolled longitudinal wires form a twin track that simplifies attachment, for greater productivity and job satisfaction
  • The cold-rolled technology produces flat wires that reduce curvature memory, for an easy-to-handle roll
  • Rolls are more manageable than sheet products and make for easy installation

ClarkDietrich Embedment Video White Paper

Stucco embedment is critical to providing enduring cladding performance on a building’s plaster/stucco walls. Embedment is a function of application whereby the lathing material is covered by the plaster. The greater the level of embedment, the less likely the wall system is to be faced with cracking, moisture penetration, rusting, and other issues. This white paper will discuss several considerations around different attributes of lathing products and their effect on embedment.
