Steel channels are among the most versatile structural components used in construction, manufacturing, transportation, and fabrication. One of the most popular lightweight structural channels is the C4 × 5.4 channel, valued for its excellent strength-to-weight ratio and adaptability across a wide range of projects. Whether you're building equipment frames, structural supports, trailers, or industrial platforms, understanding the C4 × 5.4 channel dimensions helps ensure the right material is selected for safety, performance, and cost-efficiency.
At Bobco Metals, we provide high-quality steel channels in various sizes to meet the needs of contractors, fabricators, engineers, and DIY builders. This guide explains everything you need to know about C4 × 5.4 channel dimensions, specifications, properties, uses, and buying considerations.
What Is a C4 × 5.4 Channel?
A C4 × 5.4 steel channel is a standard American structural channel (often called a C-channel) with a nominal depth of 4 inches and a weight of 5.4 pounds per foot. The "C" refers to its cross-sectional shape, while the numbers indicate its size and weight.
These channels are manufactured according to industry standards and are commonly produced from hot-rolled carbon steel. Their unique shape provides excellent structural support while remaining relatively lightweight, making them suitable for numerous structural and fabrication applications.
Standard C4 × 5.4 Channel Dimensions
Although slight variations can occur depending on manufacturing tolerances, the standard dimensions generally include:
Property | Measurement |
|---|---|
Nominal Depth | 4.00 inches |
Weight | 5.4 lb/ft |
Flange Width | Approximately 1.58 inches |
Web Thickness | Approximately 0.18 inches |
Flange Thickness | Approximately 0.26 inches |
Cross Sectional Area | Approximately 1.59 sq. in. |
These dimensions provide an excellent balance between structural strength and manageable weight, making the C4 × 5.4 channel one of the most commonly specified light structural channels.
Understanding the Naming System
Many people wonder what C4 × 5.4 actually means.
The designation can be broken into two parts:
C = American Standard Channel
4 = Approximate depth in inches
5.4 = Weight in pounds per foot
For example, a 20-foot length weighs approximately:
5.4 × 20 = 108 pounds
Knowing the weight helps estimate transportation requirements and installation costs.
Material Specifications
Most C4 × 5.4 channels are manufactured using:
ASTM A36 Steel
ASTM A572 Grade 50 (for higher strength)
ASTM A992 (in some structural applications)
These materials provide:
Excellent weldability
Good machinability
High structural strength
Reliable durability
Long service life
Mechanical Properties
The C4 × 5.4 channel offers impressive structural characteristics despite its relatively light weight.
Typical properties include:
High tensile strength
Good yield strength
Excellent resistance to bending

How to Choose the Right Channel
When selecting a C4 × 5.4 channel, consider several factors.
Load Requirements
Always determine:
Dead loads
Live loads
Dynamic loads
Safety factors
Consult a structural engineer for critical applications.
Environment
Outdoor environments may require galvanized channels for corrosion protection.
Indoor applications often use standard hot-rolled steel.
Fabrication Needs
If welding is required, confirm the selected material grade supports your fabrication process.
Project Budget
Balance:
Material cost
Transportation
Installation
Maintenance
to maximize value.
Installation Tips
For best performance:
Store steel off the ground.
Keep material dry before installation.
Use appropriate lifting equipment.
Follow engineering drawings.
Verify dimensions before fabrication.
Use proper welding procedures.
Inspect all fasteners after installation.
Proper installation significantly improves structural performance.
Maintenance Recommendations
Steel channels require relatively little maintenance.
Recommended practices include:
Annual inspections
Remove surface rust if present
Repaint damaged coatings
