Fiber Mesh Roll Sizes and Weights
Fiber mesh rolls are used in construction to reinforce plaster, screeds, waterproofing layers, and concrete surfaces. Choosing the right roll size and weight (GSM) ensures proper reinforcement and performance for specific applications. Understanding how different sizes and weights affect performance helps builders, contractors, and designers select the most suitable mesh for their projects.
What Are Fiber Mesh Roll Sizes?
Fiber mesh rolls come in various widths and lengths to suit different areas of application. Common roll sizes allow mesh to be installed efficiently on walls, floors, and large surface areas without excessive cutting and joints.
- Widths typically range from 0.5 m to 2 m
- Lengths vary from 50 m to 100 m per roll
- Custom sizes may be available from suppliers
What Is Mesh Weight (GSM)?
Mesh weight indicates the mass of the mesh per square metre and is measured in grams per square metre (GSM). It reflects the density and reinforcement capacity of the mesh.
- Lower GSM (e.g., 60–90 GSM): lighter and thinner mesh
- Medium GSM (e.g., 100–140 GSM): balanced strength and flexibility
- Higher GSM (e.g., 160–200+ GSM): strong and heavy-duty mesh
Common Fiber Mesh Roll Sizes
- 0.5 m × 50 m: Narrow rolls for detailed plaster work and tight corners
- 1 m × 50 m: Standard size for wall and render reinforcement
- 1 m × 100 m: Larger rolls for extensive surface coverage
- 1.5 m × 50–100 m: Wider mesh for large wall and floor applications
- 2 m × 50–100 m: Wide rolls for fast coverage in screeds and waterproofing
Common Mesh Weights and Uses
60–90 GSM
- Lightweight mesh for interior plaster
- Used where moderate reinforcement is sufficient
- Easy to handle and cut
100–140 GSM
- Medium-duty mesh for general plaster and render
- Good balance of strength and flexibility
- Used in walls, ceilings, and exterior finishes
160–200+ GSM
- Heavy-duty mesh for floor screeds and waterproofing
- High tensile strength for impact resistance
- Used in high-stress or high-load areas
How to Choose the Right Mesh Size and Weight
- For plaster reinforcement, medium GSM with standard width is usually sufficient
- For large wall or façade areas, wider rolls minimise joints and speed up installation
- For floor screeds or waterproofing, heavier GSM mesh improves durability
- Check project specifications for mesh requirements before ordering
Installation Tips
- Overlap mesh joints by one to two mesh widths
- Ensure full embedment in cementitious layers
- Use appropriate cutting tools to minimise fraying
- Avoid stretching mesh while fixing to prevent distortion
Common Mistakes to Avoid
- Using lightweight mesh in high-stress applications
- Insufficient overlap at joints
- Wrong mesh width for surface area, leading to excessive joints
- Embedding mesh too close to the surface
Frequently Asked Questions (FAQ)
1. What roll size is best for wall plastering?
A 1 m × 50 m roll is commonly used for plaster and render reinforcement.
2. Do heavier mesh weights mean stronger reinforcement?
Yes — heavier GSM mesh offers higher tensile strength and crack control.
3. Can mesh rolls be customised?
Some suppliers offer custom width or length based on project scale.
4. Why overlap mesh joints?
Overlapping ensures continuous reinforcement and reduces weak points.
5. Is mesh weight important for waterproofing?
Yes, higher GSM mesh enhances reinforcement in waterproofing layers.
