A metal channel brush is a brush consisting of natural or synthetic bristles held securely in place by a U-shaped metal channel and a center wire. The metal channel is first formed from flat steel into a "U". The filaments are also folded into a "U" shape with a center wire lying at the bottom of the formed filaments. The filaments and center wire are inserted into the metal channel just before the metal channel is squeezed tightly, securing the filaments and creating a "Metal Channel Strip Brush". We are also able to form this basic design into many shapes such as cylinders, cups, disks, and ovals.
