Rib Lath

Overview of Rib Lath for Construction

Rib Lath is a premium expanded metal lath stiffened by longitudinal steel ribs that are formed within the same metal sheet. This unique design combines the structural benefits of expanded mesh with integrated reinforcing ribs, delivering enhanced strength and rigidity for a wide range of plastering applications. The mesh areas are precisely expanded through a process of cutting and stretching the sheet metal, while the ribs are simultaneously roll-formed to create a consistent, durable profile along the entire length of the lath.

The innovative furred design of the mesh provides an exceptional mechanical key for plaster, cement, and render, making Rib Lath an ideal choice for constructing interior partitions, suspended ceilings, and extensive refurbishment projects. Compared to traditional flat metal lath, the ribbed profile allows for wider support spacing without compromising structural integrity. This means you can achieve faster installation with fewer support members, reducing material costs and labor time while maintaining a secure, high-performance plaster base. Rib Lath is widely recognized in the construction industry for its superior plaster adhesion, dimensional stability, and long-term durability in both commercial and residential settings.

Technical Specifications and Dimensions

Our Rib Lath is manufactured to precise specifications to ensure consistent quality, reliable performance, and compatibility with standard plastering methods. Each sheet is produced with uniform rib spacing, exact rib height, and accurate expanded mesh size to meet the demands of modern construction. The table below outlines the key technical parameters available for Rib Lath, allowing you to select the most suitable configuration for your project.

Rib Lath Specifications:

• Thickness: 0.2 mm to 0.5 mm (available in multiple gauges to suit different load requirements)
• Rib Height: 1/8 inch, 3/8 inch, 4 mm, or 10 mm (choose based on plaster thickness and structural needs)
• Rib Distance (Spacing): 100 mm or 150 mm between ribs, optimized for even plaster distribution
• Sheet Width: 610 mm (standard width suitable for typical stud spacing)
• Sheet Length: 2200 mm (custom lengths available for specific project requirements)

These dimensions have been carefully designed to work with standard construction framing, whether used with wooden studs, steel channels, or suspended ceiling grids. The combination of rib height and spacing directly influences the load-bearing capacity and plaster keying performance. For projects requiring additional reinforcement, thicker gauges and closer rib spacing are recommended. Our technical team can help you select the optimal specification for your specific application, ensuring maximum efficiency and longevity of the finished plaster system.

Applications and Benefits of Rib Lath

Rib Lath is widely used as a plaster backing on ceilings, walls, and stud partitions in both new construction and renovation projects. Its design makes it particularly suitable for areas where superior plaster adhesion is required, such as high-moisture zones, external render systems, and areas subject to vibration or movement. The expanded mesh openings create a strong mechanical bond with plaster, reducing the risk of cracking, delamination, or failure over time.

Rib Lath is also an ideal solution for refurbishing damaged or aged masonry walls. When the existing wall face has deteriorated due to disintegration, softening, or surface contamination, traditional rendering often fails because the plaster cannot achieve a secure mechanical key. Rib Lath provides a stable, clean mesh surface that allows fresh render or plaster to bond effectively, restoring the structural integrity and appearance of the wall. This application is especially valuable in heritage restoration, building repairs, and upgrading older structures to modern standards.

Additional key benefits of using Rib Lath include:

• Increased Support Spacing: The longitudinal ribs allow widening of support centers compared to standard metal lath, reducing the number of furring channels or studs required and lowering overall material costs.
• Enhanced Plaster Keying: The furred mesh design provides deeper and more uniform plaster penetration, resulting in stronger, more durable finishes with less risk of hollow spots.
• Lightweight Yet Strong: Despite its high structural strength, Rib Lath remains lightweight, making it easy to handle, cut, and install on-site without heavy lifting equipment.
• Corrosion Resistance: Available with galvanized or other protective coatings to resist corrosion in humid or exterior environments, extending the service life of the plaster system.
• Versatile Compatibility: Works well with various plaster types including cement render, gypsum plaster, and lime-based mixes for both interior and exterior use.
