Channel strip brushes are made by taking a flat piece of galvanized steel, stainless steel or aluminum, laying filaments perpendicular to the sheet metal then laying a central wire parallel to the sheet metal and then clamping the sheet metal around the retaining wire. Strip brushes can be formed to cylinder brushes, inside disk brushes, outside disk brushes, cup brushes, or remain as straight strip brushes.
