Strip brushes are long and thin. The bristles are arranged neatly and clamped between aluminum or steel channels. The bristles can be made from metal, polymer or natural substances. They can range from a few inches to a few feet in length depending on what the need is. An added bonus to these brushes is they don’t have to be straight. While this is definitely the most common form of strip brushes, they can also be curved or even round like thin wheel brushes. Many companies can even custom make brushes to make sure every client has the best possible brush.
