High Strength Galvanized High Rib Lath for Concrete Formwork Support

High Strength Galvanized High Rib Lath for Concrete Formwork Support

Our High Rib Lath, also known as High Rib Formwork Mesh, is a high-strength expanded metal formwork sheet designed specifically for concrete formwork support, slab casting, and wall reinforcement applications. Manufactured from high-quality hot-dip galvanized steel, the lath features deeply pressed ribs and V-shaped stiffeners that deliver exceptional load-bearing capacity, dimensional stability, and superior performance under high concrete pressures.

The unique 7-rib / 3-V stiffener design creates a strong, self-supporting structure that eliminates the need for traditional plywood formwork in many applications. Its open mesh pattern ensures excellent concrete flow, faster hydration, and reduced formwork stripping time. With superior anti-corrosion properties and rigidity, this galvanized high rib lath is ideal for large-scale commercial, industrial, and infrastructure projects.

Features & Benefits

• High Structural Strength: Deep ribs and V-stiffeners provide outstanding resistance to concrete pressure.

• Self-Supporting Design: Reduces or eliminates the need for plywood formwork and minimizes labor cost.

• Excellent Concrete Bonding: Open mesh pattern allows concrete to grip tightly for better structural integrity.

• Corrosion Resistant: Hot-dip galvanized coating ensures long service life in humid or high-alkaline environments.

• Fast Installation: Lightweight, easy to cut, and simple to fix onto steel or timber frameworks.

• Improved Construction Efficiency: Faster pouring, reduced stripping time, and lower overall formwork expense.
