| P1100 | 1-5/8 x 1-5/8 | 14 | General framing, ceiling grids | Plain, Zinc Dichromate, Aluminum |
| A Series (P1300) | 1-1/4 x 1-1/4 | Varies | Light-duty applications | Pre-Galvanized, Plain |
| Miniature Channel | 13/16 x 13/16 | 19 | Instrumentation, retail displays | Aluminum, Zinc Dichromate |
Understanding Strut Channel Dimensions
What are Strut Channels?
Strut channels are C-shaped metal channels designed to support various installations, such as piping, electrical conduits, and HVAC systems. Their versatility comes from the ability to connect multiple channels and fittings, allowing for customized configurations that suit specific needs.
Key Dimensions Explained
- Width and Height: The most common strut channels come in widths of 1-5/8″, 1-1/4″, and 13/16″. The height is typically the same as the width for most types.
- Gauge: The gauge indicates the thickness of the metal. Common gauges include 12 and 14, with 12-gauge being the most robust for heavy-duty applications.
- Length: Standard lengths for strut channels are typically 10′ and 20′, but custom lengths can be obtained through cutting services.
Types of Strut Channels
Heavy-Duty Strut Channel
The P1000 is the most popular heavy-duty strut channel, ideal for applications requiring substantial support. Its dimensions (1-5/8″ x 1-5/8″, 12 gauge) make it suitable for various industrial applications, including seismic bracing and trapeze support systems.
Light-Duty Strut Channel
A Series channels, such as the P1300, are designed for lighter loads and applications. They typically measure 1-1/4″ x 1-1/4″ and are ideal for retail displays and instrumentation setups.
Miniature Strut Channel
The miniature channel, measuring 13/16″ x 13/16″ and available in 19 gauge, is perfect for applications requiring minimal load support, such as smaller equipment and light-duty installations.
Applications of Strut Channels
Construction and Industrial Use
Strut channels are widely used in construction and industrial settings for mounting HVAC systems, plumbing, and electrical conduits. Their adjustable nature allows for easy modifications as project needs change.
Seismic Bracing
Many strut channels, like the P1000, are OPA approved for seismic bracing, making them essential in earthquake-prone areas. Their robust design helps maintain structural integrity during seismic events.
Custom Framework
Strut channels are also used for creating custom frameworks in various applications, including staging, shelving, and display systems. Their modular design allows for easy assembly and reconfiguration.
Technical Features Comparison
| Strut Type | Width (inches) | Height (inches) | Thickness (gauge) | Material Options | Approved for Seismic Bracing |
|---|---|---|---|---|---|
| P1000 | 1-5/8 | 1-5/8 | 12 | PG, HG, SS, PL, GR, ZD | Yes |
| P1100 | 1-5/8 | 1-5/8 | 14 | PG, PL, ZD | No |
| A Series (P1300) | 1-1/4 | 1-1/4 | Varies | PG, PL | No |
| Miniature Channel | 13/16 | 13/16 | 19 | Al, ZD | No |
