What is a wood C-channel?

A wood C-channel (or C-section) is a lumber profile shaped like the letter C in cross-section: two horizontal flanges (top and bottom) connected by a vertical web on one side. It is used in framing, cabinetry, and structural applications.

How is the cross-sectional area calculated?

The outer rectangle area minus the inner void area gives the net section area. Inner void width = outer width − web thickness; inner void height = outer height − (2 × flange thickness). Weight = net area × length × density.

Which wood density should I use?

Use the oven-dry or air-dry density for your species at the moisture content you expect in service. Common values: Douglas Fir ~32 lb/ft³, Southern Yellow Pine ~35 lb/ft³, Oak ~45 lb/ft³, and Pine (Eastern White) ~25 lb/ft³.

Can I enter metric dimensions?

This tool uses US customary units (inches for cross-section, feet for length, lb/ft³ for density, and pounds for weight). For metric inputs, convert: 1 inch = 25.4 mm, 1 foot = 0.3048 m, 1 lb/ft³ ≈ 16.018 kg/m³.

Why does the tool show an error for my dimensions?

The inner void must have positive dimensions. Check that the web thickness is less than the outer width and that 2× flange thickness is less than the outer height. If not, the section has no hollow area and is a solid block, not a channel.
