  • This product complies with
  • ASTM C847: Standard specification for metal lath. Ensures the rigidity, strand size, and structural integrity of the ribbed metal lath.
  • BSEN 10327-2004: Continuously hot-dip coated strip and sheet of low carbon steels for cold forming
Ribbed Lath / Rib Lath Features & Benefits 
Q1: What is Rib Lath?
A: Ribbed Lath is a reinforced metal lath with longitudinal V-shaped ribs designed to provide higher strength and rigidity compared with standard metal lath. It is commonly manufactured from pre-galvanized steel and widely used in plastering, rendering, concrete construction, and fireproofing applications.

 

Q2: What are the main advantages of Rib Lath?
A: Ribbed Lath offers excellent mechanical bonding performance due to its mesh openings and ribbed structure. It helps plaster, cement, or render firmly adhere to the surface, reducing the risk of cracking or peeling over time.
Its reinforced ribs also provide greater tensile strength and support, making it suitable for larger spans and demanding construction environments.

 

 

Q3: Why is Ribbed Lath suitable for plastering applications?
A: The ribbed mesh structure provides strong keying for scratch coats and plaster applications. It helps maintain a consistent plaster thickness and improves bonding performance for walls, ceilings, and decorative plaster works.
Ribbed Lath is also commonly used for plaster machine applications due to its stable structure and easy installation.

 

Q4: Can Ribbed Lath be used as permanent formwork?
A: Yes. High Rib Lath is frequently used as a stay-in-place or permanent formwork system for concrete construction. After concrete pouring, the lath remains embedded within the structure, eliminating the need for formwork removal and improving construction efficiency.

 

 

Q5: What construction applications commonly use Ribbed Lath?
A: Ribbed Lath is commonly used for:
  • Concrete construction joints
  • Walls and ceilings
  • Partition walls
  • Fireproofing for steel beams and columns
  • Tunnel walls and support structures
  • Basement waterproof protection layers
  • Ornamental plaster works
  • Large-area plastering applications

 

Q6: What material is Ribbed Lath made from?
A: Ribbed Lath is typically produced from pre-galvanized steel, providing good corrosion resistance and long-term durability for construction applications.
