When it comes to structural steel design, precision and consistency make all the difference. At Bobco Metals, we understand that engineers, builders, and fabricators rely on accurate steel channel dimensions to ensure their projects meet safety, strength, and performance requirements. Two of the most commonly used steel channel types in construction and fabrication are the C6x8.2 and the C8 channel. This guide will help you understand their dimensions, uses, and how Bobco Metals ensures you get the highest quality material every time.

Understanding the C6x8.2 Channel

The C6x8.2 channel is a widely used structural steel section known for its balance between strength and weight. The “C” refers to its channel shape, while “6” represents its nominal depth in inches, and “8.2” indicates its weight in pounds per foot.

The C6x8.2 dimensions are as follows:

  • Depth (H): 6.00 inches

  • Flange Width (B): 1.920 inches

  • Web Thickness (t): 0.200 inches

  • Weight: 8.2 lb/ft

This size is popular in construction framing, machinery bases, supports, trailers, and other load-bearing applications. It offers excellent rigidity while maintaining a relatively lightweight structure, making it easy to handle and install.

At Bobco Metals, we stock and cut C6x8.2 steel channels to precise measurements, ensuring each piece meets ASTM A36 or A992 specifications for strength and consistency.

Applications of C6x8.2 Steel Channels

The C6x8.2 channel is a versatile structural shape used in a variety of industries:

  1. Building and Construction: Ideal for framing, columns, lintels, and bracing in both commercial and residential structures.

  2. Manufacturing and Fabrication: Commonly used in machinery frames, conveyor supports, and assembly lines.

  3. Transportation: Used in trailer frames, truck beds, and loading ramps for its lightweight yet strong design.

  4. Infrastructure Projects: Perfect for bridges, walkways, and other civil engineering applications requiring load-bearing reliability.

Bobco Metals ensures all C6x8.2 channels are accurately measured, properly cut, and ready to meet your exact specifications — whether for large-scale projects or smaller fabrication jobs.

Exploring the C8 Channel

The C8 channel is another standard section that provides added depth and strength compared to the C6x8.2. The number “8” in the designation refers to its 8-inch depth, making it suitable for heavier structural applications.

Typical C8 channel specifications include:

  • Depth (H): 8.00 inches

  • Flange Width (B): 2.260 inches

  • Web Thickness (t): 0.220 inches

  • Weight Range: 11.5 to 18.75 lb/ft (depending on the variant, e.g., C8x11.5, C8x13.75, C8x18.75)

This extra size allows the C8 channel to handle greater loads, resist deflection, and provide enhanced stability.

At Bobco Metals, we stock several C8 channel sizes to meet different engineering needs. Whether you're designing large-scale frameworks or reinforcing heavy equipment, our precision-cut C8 channels ensure consistent performance and durability.

Comparing C6x8.2 vs. C8 Channel

While both the C6x8.2 and C8 channel are part of the same family of structural shapes, they serve slightly different purposes. The C6x8.2 offers a lighter, more compact profile suitable for medium-duty construction, while the C8 channel provides increased strength and rigidity for heavier structural loads.

At Bobco Metals, we help you choose the right steel channel for your specific project requirements. Our experts can recommend the ideal size, thickness, and material grade based on load capacity, structural design, and cost-efficiency.
