If you’re working in construction, metal fabrication, or industrial projects, you’ve probably come across the term C4 x 5.4 channel. But unless you live and breathe steel specs, those numbers can feel cryptic.
Here’s the breakdown:
- C4 = The channel is 4 inches deep.
- 5.4 = The channel weighs 5.4 pounds per foot.
In this article, we’ll walk you through the C4 x 5.4 channel dimensions, its weight, physical specs, and the wide range of uses in 2025. We’ll also compare it to other standard channels so you can choose the right size for your project.
Understanding C4 x 5.4 Channel Dimensions
Steel channels are named systematically, and understanding the designation saves you time (and prevents costly mistakes).
- “C” stands for C-channel, shaped like the letter C with a wide web and shorter flanges.
- The first number (4) is the nominal depth in inches.
- The second number (5.4) is the weight in pounds per linear foot.
So, a C4 x 5.4 channel is a 4-inch-deep steel channel that weighs 5.4 lbs per foot of length.
This lightweight yet sturdy profile is highly versatile, especially where moderate strength is required without adding excess weight.
Technical Specifications of C4 x 5.4 Channel
Here are the standardized C4 x 5.4 channel dimensions and related properties:
| Specification | Value |
|---|---|
| Depth (D) | 4.00 in |
| Flange Width (BF) | 1.58 in |
| Web Thickness (TW) | 0.184 in |
| Weight per Foot | 5.4 lbs/ft |
| Section Modulus | 1.54 in³ |
| Moment of Inertia | 3.07 in⁴ |
These specs matter because they tell you how much load the channel can carry, how stiff it will be in your structure, and how much it will cost in both material and transportation.
Common Uses of C4 x 5.4 Channels in 2025
The balance between strength and weight makes the C4 x 5.4 channel a favorite across industries. In 2025, we’re seeing it used for:
1. Structural Support
Ideal for small-to-medium load-bearing frameworks like mezzanines, roof purlins, or stair stringers.
2. Fabrication
Common in machine frames, racks, shelving units, and equipment supports.
3. Transportation
Light enough to be used in trailers, truck frames, and agricultural equipment where weight savings matter.
4. Construction
Used in residential and light commercial projects for reinforcement and framing where heavy beams would be excessive.
5. DIY and Custom Builds
Favored by metal fabricators and hobbyists who want durable material without overbuilding.
In short, when you need strength without bulk, the C4 x 5.4 channel dimensions hit the sweet spot.
How C4 x 5.4 Compares to Other Channels
Choosing the right channel means weighing strength, size, and cost. Here’s how the C4 x 5.4 stacks up against other popular options:
| Channel Size | Depth (in) | Weight (lbs/ft) | Typical Use Case |
|---|---|---|---|
| C3 x 4.1 | 3.00 | 4.1 | Light bracing, small frames |
| C4 x 5.4 | 4.00 | 5.4 | Balanced strength, stair stringers, trailers |
| C6 x 8.2 | 6.00 | 8.2 | Heavy bracing, structural frameworks |
| C8 x 11.5 | 8.00 | 11.5 | Larger commercial/industrial load-bearing |
This shows where the C4 x 5.4 channel dimensions fit. It’s the mid-range workhorse: stronger than light channels but more economical than heavy-duty ones.
