metal furring channel sizes and specifications

Metal furring channels are commonly used in ceiling and wall framing to support drywall, plaster, or other finishes. Their sizes and specifications vary depending on the manufacturer, building codes, and application requirements. Below are the typical details:

1. Standard Sizes

Metal furring channels come in various sizes, typically measured by width, height, and thickness. Some common dimensions include:

• Width: 16mm (5/8"), 25mm (1"), 38mm (1.5")
• Height: 12mm (1/2"), 19mm (3/4"), 25mm (1")
• Thickness: 0.4mm – 1.2mm (varies by application)

• Custom lengths available based on project requirements

3. Materials & Coating

• Material: Galvanized steel (G40, G60, G90)
• Coating: Zinc-coated (corrosion-resistant)

4. Types of Metal Furring Channels

• C-Shaped Furring Channel – Used for ceiling and wall applications
• Hat Furring Channel – Provides spacing for moisture control and ventilation
• Z-Furring Channel – Often used for exterior walls to hold insulation

5. Load-Bearing Capacity

• Depends on gauge thickness and spacing between supports
• Typically spaced 16" or 24" on center (O.C.)

6. Installation Guidelines
