Metal Back Strip Construction and Information

Constructing brush.

Metal Back Strip Brushes consist of densely compressed synthetic, natural bristle or wire filaments laid down over a continuous metal channel while being formed into a "U" shape. A core wire is inserted over the filament material and forced down into the partially formed metal backing. The core wire causes the fill material to form vertically as the metal backing forms and closes over the core wire filament.

Channel back sizes.

Metallic strip/backing is available in galvanized or stainless steel. The backing typically works in harmony with the desired bristle diameter and density. Sizes ranging from #3 to #10 backing. Channel backing width and height may vary depending on fill amount.

Brush shapes.

Specialized geometries (The shape shifter of the brush world) all metal back strip brushes start from straight strip. Due to the malleable nature of the strip a variety of shapes can be formed.

Mounting Methods.

Metal back strip brushes can be mounted either by an alligator clip or an extruded aluminum holder. The prongs on the alligator clip wrap around the brush to allow a tight hold on a section of the strip brush. Metal back strip brushes slide into an extruded aluminum holder for mounting purposes. Aluminum holders are extruded in various end view shapes to match a specific application.
