Product Specification

Reinforced Expanded Metal High Rib Lath Sheet for Wall Plaster Backing

Our High Rib Lath Sheet is a reinforced expanded metal lath designed to provide superior mechanical strength and enhanced bonding performance for wall plaster backing systems. Manufactured from premium galvanized steel sheets, the lath is expanded and pressed into a ribbed structure that delivers exceptional rigidity, stability, and load-bearing capacity.

The deeply formed main ribs and V-shaped stiffeners offer strong support for thick plaster layers, ensuring uniform adhesion and preventing cracking, sagging, or delamination. Its open expanded mesh pattern allows plaster or mortar to effectively interlock with the lath, improving overall wall integrity and providing a reliable base for interior and exterior finishing applications.

Lightweight, easy to cut, and fast to install, this high rib expanded metal lath is widely used in residential, commercial, and industrial wall construction, especially where enhanced support and long-term durability are required.
