What are the standard metal furring sizes?

Standard metal furring channel sizes are fairly consistent worldwide, with slight regional differences depending on building codes (US, Australia, Europe, Canada). Below is a clear, practical breakdown used in drywall ceilings and wall systems.

1. Common Metal Furring Channel Profiles

The most common shape is the hat channel (Ω-shape), also called:

• Furring channel

• Hat furring

• Ceiling furring channel

2. Standard Metal Furring Channel Sizes

Width (Face Width)

• 16 mm (≈ 5/8")

• 25 mm (≈ 1")

• 35 mm (≈ 1-3/8")

? 25 mm is the most widely used size for drywall ceilings.

Depth / Height

• 7–10 mm (light-duty wall leveling)

• 12 mm

• 19 mm

• 22–25 mm (heavy-duty ceiling applications)

Thickness (Steel Gauge)

• 0.45 mm

• 0.50 mm

• 0.55 mm

• 0.60 mm

Thicker gauges are used for higher load capacity and commercial projects.

Standard Lengths

• 2.4 m

• 3.0 m

• 3.6 m

• 4.0 m

(Custom lengths up to 6 m are also available.)

3. Regional Size References

United States / Canada

• Typical size: 25 mm × 19 mm

• Length: 8 ft, 10 ft, 12 ft

• Thickness: 0.45–0.55 mm

Australia / New Zealand

• Common size: 16 mm or 28 mm face width

• Height: 19 mm or 28 mm

• Thickness: 0.55 mm (BMT)

Europe

• Popular sizes:

  • CD 60 × 27 mm

  • Hat channel 50 × 15 mm

• Thickness: 0.6 mm

4. How to Choose the Right Size

• Ceilings: 25 × 19 mm, thickness ≥ 0.5 mm

• Walls (leveling): 16 × 7 mm or 16 × 10 mm

• Heavy boards / cement board: ≥ 0.6 mm thickness

• Long spans: Use deeper profiles (22–27 mm)

5. Quick Tip

Always check:

• Local building codes

• Ceiling load requirements

• Board thickness and spacing
