Expanded Metal Lath Coil (Brick Reinforcement)
Browse our range of expanded metal lath coils for brick reinforcement, available in multiple widths and materials for reliable masonry support.
Expanded Metal Lath Coil (Brick Reinforcement)
Expanded metal lath (EML) coils are used to reinforce brick and blockwork, helping reduce cracking and improve structural stability. They are commonly installed within mortar joints to strengthen masonry and support plaster and render finishes.
EML Coils at a Glance
| Material | Length | Widths Available | Best For |
|---|---|---|---|
| Galvanised steel | 20m | 63mm, 100mm, 175mm, 225mm, 305mm | Internal masonry and general reinforcement |
| Stainless steel | 20m | 63mm, 100mm, 175mm, 225mm | External and damp-prone environments |
What is expanded metal lath used for?
- Reinforcing brick and blockwork
- Reducing cracking in plaster and render finishes
- Strengthening mortar joints
- Supporting masonry around openings and weak points
Where should EML coils be used?
Expanded metal lath coils are installed within mortar joints in areas where additional reinforcement is needed.
- Above doors and window openings
- Around movement joints
- In long or unsupported wall sections
- Areas prone to cracking or structural stress
Galvanised vs stainless steel EML
Galvanised EML coils are suitable for internal applications and general masonry reinforcement. They provide reliable performance in standard building conditions.
Stainless steel EML coils are designed for external use or damp environments where corrosion resistance is essential. They offer long-term durability in more demanding conditions.
Choosing the right width
The width of the EML coil should match the application and level of reinforcement required. Wider coils provide greater coverage and support in larger or higher-stress areas.
- 63mm – suitable for lighter reinforcement and smaller joints
- 100mm – general-purpose masonry reinforcement
- 175mm–225mm – increased coverage for larger areas
- 305mm – maximum coverage for heavy-duty applications
Supplied in coil form for site use
All expanded metal lath is supplied in 20m coils, making it easy to handle on site and suitable for continuous reinforcement across larger sections of masonry work.

EML Coil FAQs
What is expanded metal lath used for in brickwork?
Expanded metal lath is used to reinforce masonry by strengthening mortar joints and reducing the risk of cracking.
Where should EML be installed?
EML is typically installed above openings, around movement joints, and in areas where additional structural support is required.
Should I use galvanised or stainless steel EML?
Galvanised EML is suitable for internal use, while stainless steel is recommended for external or damp environments where corrosion resistance is needed.
What width EML coil should I choose?
The width depends on the level of reinforcement required. Wider coils provide more coverage and are used in larger or higher-stress areas.
