What Is Galvanized Expanded Metal Lath Screwfix?

Galvanized expanded metal lath screwfix refers to heavy-duty, hot-dip galvanized expanded metal lath specifically engineered for secure installation with screws, widely available at hardware suppliers like Screwfix in the UK. It is a ribbed, diamond-patterned metal sheet used to reinforce plaster, stucco, render, and cement coatings on walls, ceilings, and exterior surfaces.

This lath is made from cold-rolled carbon steel that is slit, expanded, and then coated with a thick layer of zinc via hot-dip galvanization. The unique diamond and rib design creates a strong mechanical bond with plaster and render, preventing cracking, shrinking, and detachment over time.

The “screwfix” designation highlights its easy installation using standard wood or masonry screws, making it a favorite among DIY enthusiasts, small builders, and professional contractors. It is the most widely used reinforcement product in plastering and external wall insulation systems.

Unlike paper-backed or fiberglass lath, metal expanded lath provides structural rigidity, impact resistance, and longevity—making it ideal for both interior plastering and exterior stucco applications.

Key Specifications of Galvanized Expanded Metal Lath

Our galvanized expanded metal lath meets and exceeds British and European standards, matching the quality of Screwfix-grade products. Below are the standard specifications for professional construction use:

Our lath features a self-furring rib design that creates a 1/8-inch gap behind the mesh, allowing plaster to fully encapsulate the metal for maximum bonding strength. This design is identical to premium galvanized expanded metal lath screwfix products.

All our lath products are flexible yet rigid, easy to cut, bend, and form to curved surfaces, and compatible with all types of plaster, render, and stucco mixes. Full specifications are available in our metal mesh product catalog.

Why Choose Galvanized Expanded Metal Lath for Screw Fixing?

Galvanized expanded metal lath is the preferred choice for screw-fixed plaster reinforcement due to its unique combination of strength, durability, and ease of installation:

Secure Screw Fixing – The rigid metal structure holds screws tightly without tearing or pulling loose, unlike flimsy mesh alternatives. Ideal for fixing to wood studs, metal framing, and masonry surfaces.

Superior Corrosion Resistance – Hot-dip galvanized coating prevents rust and corrosion, even in damp interior environments and exterior weather conditions. Lasts decades without degradation.

Maximum Plaster Bond – Diamond pattern and ribbed design lock plaster into place, eliminating cracking, hollow spots, and delamination. Creates a monolithic, durable surface.

Structural Reinforcement – Adds rigidity to walls and ceilings, resisting impact damage and structural movement. Essential for high-traffic areas and external walls.

Easy Installation – Lightweight and flexible, easy to cut with tin snips, form to curves, and install with standard screws. Perfect for both professionals and DIY users.

Cost-Effective – Low material cost combined with long service life provides exceptional value compared to other reinforcement systems.

Primary Applications of Galvanized Expanded Metal Lath

Our Screwfix-grade galvanized expanded metal lath is used across all areas of construction and renovation:

• Interior Plastering – Reinforcement for walls, ceilings, columns, and curved surfaces
• Exterior Stucco & Render – External wall insulation, finish coat reinforcement, and weatherproof cladding
• Fireproofing Systems – Structural fire protection for steel beams and columns
• Under-Tile Support – Stable base for wall and floor tiles in wet areas
• Repair & Renovation – Patching damaged walls, reinforcing weak plaster, and resurfacing old surfaces
• Concrete Reinforcement – Lightweight reinforcement for thin concrete overlays and screeds
• Insulation Board Fixing – Secure backing for thermal insulation panels

It is the universal standard reinforcement product in the construction industry, recognized by builders, architects, and code officials worldwide for its reliability and performance.

How to Install Galvanized Expanded Metal Lath with Screws

Installing our galvanized expanded metal lath using the screwfix method is straightforward and follows industry best practices:

Step 1: Surface Preparation – Clean and prepare the wall/ceiling surface, ensuring framing studs are spaced 16–24 inches apart.

Step 2: Cutting & Fitting – Cut lath to size using tin snips. Overlap sheets by 1 inch for continuous reinforcement.

Step 3: Screw Fixing – Use #8 zinc-plated or stainless steel screws with washers. Fix every 6 inches on studs and every 8 inches in field areas.

Step 4: Embedding & Reinforcing – Ensure ribs face outward to create a plaster key. Fold lath around corners for continuous reinforcement.

Step 5: Plaster Application – Apply scratch coat, brown coat, and finish coat directly onto the lath, ensuring full encapsulation of the mesh.

Proper screw fixing ensures the lath remains rigid and stable during plaster application, resulting in a flawless, long-lasting finish.
