Multipurpose Low-Carbon Steel U-Channels

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It can also be surface-hardened with heat treatment.

U-Channel—U-channels have thin, straight legs. They’re often used as edge protectors, cable trays, and trim.

C-Channel—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-Channel—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

U-Channel Trade Size—The U-channel trade size 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.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Weldable 4130 Alloy Steel Triangles

Weld these alloy steel triangles to strengthen joints in structural applications. They're also known as gussets. They have clipped corners that leave room for a weld bead, so you can make stronger welds. Made from 4130 alloy steel, also known as chrome-moly steel, these triangles have low carbon content for good weldability. To increase their wear resistance, you can harden them with heat treating.
