Low-Carbon Steel U-Channels
- Yield Strength: 36,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Not Rated
- Fabrication: Hot Rolled
- Specifications Met: ASTM A36
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It can also be surface-hardened with heat treatment. These U-channels are manufactured to meet ASTM A36 standards for performance and quality.
U-channels have thin, straight legs. They’re often used as edge protectors, cable trays, and trim.
C-channels are stronger than U-channels. They have thicker legs, and their tapered design distributes loads more evenly. They’re often used for structural purposes, such as frames and supports.
MC-channels are the strongest option, as they have wide bases and the thickest legs. Since they have straight legs, it’s easier to attach bolts to them than C-channels, which have tapered legs.
The U-channel trade number indicates the channel’s outside width and weight in lbs./ft. This gives you an easy reference for selecting the right size and strength for your needs.
