For anyone who is new to the industrial brush industry, the first product you need to understand is the metal back strip brush.
A metal back strip brush can be considered the foundation of industrial brushes. Many industrial brushes are either directly made from metal back strip brush or created through further processing and forming.
By understanding metal back strip brush, you can quickly understand the basic structure, manufacturing process, and application possibilities of many industrial brushes.
In this article, we will introduce the main types of industrial brushes that are made from metal back strip brush and explain how they are manufactured and where they are used.
What Is Metal Back Strip Brush?
A metal back strip brush is a continuous strip brush consisting of:
Metal channel backing
Filament bristles
During production, brush filaments are inserted into a metal channel and fixed tightly by an anchor wire. The most common backing materials include:
Galvanized steel channel
Stainless steel channel
The bristles can be customized according to different applications, including:
Nylon
Polypropylene
PBT
Steel wire
Animal hair
Because of its flexible structure and customizable design, metal back strip brush can be processed into many different industrial brush products.
1, Spiral Brush (Spring Brush)
The first type of industrial brush made from metal back strip brush is the spiral brush, also called a spring brush.
During production, an additional winding device is added to the strip brush manufacturing process. The metal back strip brush is then wound into a spiral shape with a specific diameter.
Depending on the winding direction, spiral brushes can be divided into two types:
Inside Spiral BrushWhen the strip brush is wound upward in a clockwise direction, it creates an inside spiral brush.
Outside Spiral BrushWhen the strip brush is wound downward in a counterclockwise direction, it creates an outside spiral brush.
Applications of Spiral Brush
Spiral brushes are widely used in many industries, including:
Cleaning climbing ropes
Removing rust from wires
Cleaning cylindrical surfaces
In addition, an outside spiral brush can be installed on a shaft to create a spiral strip roller brush, which is commonly used in continuous cleaning systems.
2, Disk Brush (Circular Brush)
Another common industrial brush made from metal back strip brush is the disk brush, also known as a circular brush.
The manufacturing method is similar to spiral brush production.
First, the metal back strip brush is wound into a spiral shape. Then, an additional cutting process is added to cut the spiral brush into individual circular pieces.
Unlike spiral brushes, which contain multiple continuous coils, a disk brush has only one circular loop where the beginning and end are connected.
According to the bristle direction, disk brushes can be divided into:
Inside Disk BrushThe bristles face inward.
Outside Disk BrushThe bristles face outward.
Applications of Disk Brush
Disk brushes are commonly used for:
Shaft sealing
Rod surface cleaning
Rotating equipment cleaning
3, Cup Strip Brush
A cup strip brush is another product made by secondary processing of metal back strip brush.
During manufacturing, a special bending machine bends the strip brush horizontally to the left or right, forming a cup-shaped structure.
The main feature of cup strip brush is:
The bristles face upward
The brush shape looks similar to a cup
Applications of Cup Strip Brush
Cup strip brushes are mainly used in:
High-pressure floor cleaning machines
Vacuum cleaner nozzles
Surface cleaning equipment
4, Wavy Strip Brush
A wavy strip brush is made by processing a metal back strip brush through an automatic bending machine.
The machine bends the strip brush into a regular wave shape.
The biggest challenge in manufacturing wavy strip brush is maintaining:
Consistent bending angle
Uniform wave shape
Stable product dimensions
Small differences in bending can affect installation and performance.
Applications of Wavy Strip Brush
One of the most common applications is:
Dry ski slopes
The special wave structure provides continuous contact and support, making it suitable for artificial skiing surfaces.
Why Is Metal Back Strip Brush So Important?
Metal back strip brush is widely used as a base material because it can be customized and transformed into many different brush designs.
By changing:
Brush shape
Bending direction
Diameter
Length
Bristle material
Bristle density
manufacturers can create different industrial brushes for specific applications.
