Request a QuoteWhat Is a Strip Brush?
A custom strip brush is a linear industrial brush made with a metal-channel or polymer backing and a dense filament fill. Strip brushes—also called brush strips—provide a flexible working edge for sealing, guiding, shielding, dust control, and light wiping around machines, conveyors, panels, and enclosures.
For OEM and replacement projects, the visible brush is only part of the fit. Backing profile, holder or track dimensions, trim height, filament material, fill density, and mounting direction determine whether the strip installs correctly and makes the intended contact without rework.
Strip Brush Profiles and Types
Choose the carrier or backing profile first, then confirm the filament and trim. The backing profile controls installation; the filament trim profile controls how the working edge meets the surface.
Formed strip brushes
- Radius edges and curved machine openings
- Internal or external ring configurations
- Circular, cup, or application-shaped brush paths
- Formed to a drawing, sample, or required radius
Flexible strip brushes
- Flexible or rigid polymer-backed profiles
- PVC, PP, TPV, or TPE backing options
- Direct mounting around corners or uneven paths
- Light sealing at equipment and enclosure openings
Spiral / coil strip assemblies
- Wound strip-brush assemblies
- Special circular or helical contact paths
- Stationary or rotary installation must be identified
- Rotary builds may require a spiral or cylinder-brush review
How Strip Brush Backings and Fill Are Built
The backing carries and mounts the brush, while the filament provides the working contact. Metal-channel and polymer-backed strip brushes use different carrier constructions and should not be specified as the same profile.
Metal channel backing
A formed metal channel creates the structural base of the brush. Galvanized steel, stainless steel, or aluminum may be selected according to the holder, environment, stiffness, and corrosion requirements; the exact grade and finish should be confirmed before production.
Center wire and fill retention
In a metal-channel strip brush, the center wire helps retain the filament after the channel is closed. Channel size, fill quantity, and retention must be matched to the required stiffness and repeated contact duty.
Filament and working edge
The filament controls flexibility, recovery, wear, surface contact, and environmental compatibility. Filament material, diameter, density, trim height, and edge shape should be selected together.
Filament trim profiles
The filament trim profile is the shape of the working edge, not the metal or polymer mounting profile. It changes how the brush enters the gap and distributes contact across the surface.
Flat
For even contact across straight sealing, guiding, and light-wiping surfaces.
Beveled corner
For gradual entry when contact begins from one side or near a corner.
Notched
For clearing hardware, joints, or selected areas along a stepped surface.
Slanted trim
For directional contact or a gradual change in trim height along the strip.
Filament Materials for Industrial Strip Brushes
Backing material controls mounting strength and environmental resistance; filament material controls contact with the workpiece. The options below refer to the filament. Confirm moisture, chemicals, heat, surface sensitivity, static requirements, and required documentation before selection.
Nylon
Nylon strip brushes are a general-purpose choice for sealing, guiding, dust control, and light wiping where wear resistance, flex recovery, and stable contact are needed.
Polypropylene
A lightweight synthetic filament considered for damp, washdown-prone, or selected chemical environments. Chemical compatibility and working temperature should be confirmed for the actual process.
Steel / stainless steel wire
For more aggressive contact, higher-temperature duty, or metalworking applications. Confirm whether carbon steel or stainless steel is required and whether the workpiece can tolerate metal-filament contact.
Brass / phosphor-bronze wire
Copper-alloy filament options for selected conductive, static-related, or softer metal-contact applications. Confirm the electrical requirement and workpiece sensitivity before selection.
Natural fibers
For soft contact, fine dusting, light polishing, or product handling where a natural-fiber build is suitable. Moisture, shedding, hygiene, and documentation requirements must be reviewed.
Common Industrial Uses
Industrial strip brushes provide a flexible contact edge where rigid seals, guides, or wipers are unsuitable. Common OEM and replacement uses include:
Conveyor guiding and product handling
Transfer-point wiping and containment
Production-line surface cleaning
Product separation and lane guiding
Concrete-block machine cleaning
Door and enclosure sealing
Elevator and escalator edge sealing
Rack and enclosure cable entry

This part matters to procurement because a strip brush only works if the build matches the holder, trim, material, and application duty. We review fit before production and inspect the dimensions that affect installation and performance.
Drawing or sample review
We review the drawing, holder reference, marked photo, or replacement sample to confirm the strip configuration, channel size, trim, and mounting logic before production starts.
Backing and fill preparation
The required backing material, channel size, and filament type are prepared according to the approved specification and service environment.
Fill insertion and trim finishing
Filament and center wire are formed into the channel, then the strip is cut to section length and trimmed to the required profile or edge condition.
Fit and dimension inspection
Before packing, we check the dimensions that affect the job most directly, such as channel fit, trim length, section length, and visible finish.
Packing by project and shipment
Brush sections are protected and packed according to their type, length, quantity, destination, and transport requirements.
Packing for Long Strip Brush Sections
Long metal-channel strip brushes can be protected individually for batch handling and packed in reinforced wooden cases when the section length and shipping route require additional support.
The Common Pitfalls When Purchasing
These are the most common mistakes buyers make when strip brush specifications are sent without enough application and fit detail.
Assuming the old channel number guarantees fit
Pitfall: Channel references are useful, but replacement fit can still fail when holder dimensions or manufacturer standards differ.
Tip: Send the holder size, marked dimensions, or an old sample whenever possible so the fit can be checked before production.
Specifying trim and material without the real duty
Pitfall: A strip brush that looks correct on paper can still underperform when the contact surface, debris type, speed, or environment is not shared.
Tip: Define whether the brush is for sealing, guiding, dust control, light wiping, or static-related duty and describe the operating environment.
Overlooking mounting direction and installation method
Pitfall: A correct strip brush build can still fail in the project if the holder style, mounting face, or installation direction is not considered.
Tip: Describe how the strip will be mounted so the backing style, holder match, and section layout can be reviewed before quoting.
Confusing mounting profile with filament trim profile
Pitfall: A backing or holder profile controls installation, while a flat, beveled, notched, or slanted trim describes the working filament edge.
Tip: Show the holder cross-section and the required working-edge shape separately on the drawing or marked photo.
FAQ
Can you match my existing holder or channel size?
Yes. A holder sample, old strip sample, or drawing is the safest way to confirm replacement fit, especially when reference numbers vary between manufacturers.
What is the maximum strip length per section?
Straight strip brush sections can be custom manufactured up to 3 m. Flexible strip brushes can be supplied in longer continuous lengths depending on the backing or profile construction. Final dimensions, section layout, packing, and shipping requirements are confirmed for each project.
Can I order a sample before production?
Yes. Samples are commonly used to confirm fit, trim, mounting, and material performance before batch production.
When should I use strip brush instead of a roller brush?
Use strip brush for fixed linear contact such as sealing, guiding, or light wiping. Use a roller format when the brushing surface needs to rotate on a shaft or core.
Do you offer custom trim profiles?
Yes. Flat, beveled, notched, and slanted filament trims are common. The mounting or holder profile should be shown separately so the working edge and installation fit are both clear.
Which backing and holder materials are available?
Metal-channel strip brushes may use galvanized steel, stainless steel, or aluminum backing, while flexible or rigid strip brushes may use polymer backing. Holder material, grade, finish, and compatibility should be confirmed from the drawing and operating environment.
Do you ship internationally?
Yes. Packing method and delivery plan depend on section length, quantity, destination, and customization level.
