Abstract: An elongated C-channel construction member made of a wood composite material. The C-channel has a blank panel with a generally planar panel front and panel back, a top, a bottom and two sides. The panel front has two grooves extending from the top to the bottom of the blank panel. Each groove has a depth approximately equal to a thickness of the blank panel. A flat back support is adhered to the panel back. The flat back support retains the blank panel with the grooves in a sheet form. The two grooves divide the blank panel into a web and two flanges. The flanges fold upward and generally perpendicular to the panel front thus forming the C-channel.
