Rib Lath, also known as ribbed lath or ribbed metal lath, is a type of metal mesh used in construction and masonry applications. It is typically made from galvanized steel or stainless steel and features a series of ribs or ridges that run perpendicular to the length of the lath.

One of the main advantages of Rib Lath is its ability to provide a strong, durable, and stable base for plastering or rendering. The ribs on the lath help to create a mechanical bond between the plaster and the wall, ensuring a secure and long-lasting finish. Rib Lath is also resistant to corrosion, making it suitable for use in both indoor and outdoor applications.

Rib Lath can be used in a variety of applications, including:

1. Reinforcement of plaster and stucco on walls and ceilings
2. Support for tile and stone installations
3. Strengthening of masonry and brickwork
4. Repair and restoration of damaged walls

The dimensions of Rib Lath can vary depending on the specific application and manufacturer, but common sizes include widths of 12 inches, 16 inches, and 24 inches, and lengths of 100 feet or 50 feet. The thickness of the lath and the spacing between the ribs can also vary.

To install Rib Lath, it is typically attached to the wall using nails or screws, with the ribs running vertically. The lath is then covered with a layer of plaster or render, which adheres to the ribs and provides a strong, durable finish. Proper installation is essential to ensure the effectiveness of the Rib Lath and the quality of the final result.
