Orange Skirtboard
Premium abrasion-resistant rubber with a built-in visual wear indicator for conveyor loading zones
Orange skirtboard is a premium abrasion-resistant rubber compound — typically natural rubber or an SBR/NR blend — engineered for high-wear conveyor loading zones. The distinctive orange color is not cosmetic: it functions as a built-in wear indicator. When the orange surface wears through to the black substrate, maintenance crews know immediately that it is time to replace the skirtboard. This simple visual cue eliminates guesswork, reduces unplanned downtime, and helps operations maintain consistent containment at transfer points.
What Is Orange Skirtboard?
Orange skirtboard is a specialty rubber skirting material installed along the edges of conveyor belt loading zones and transfer points. It seals the gap between the conveyor belt surface and the chute sidewalls, containing material and preventing spillage. Two construction styles are common:
- Dual-layer construction — An orange wear layer bonded to a black rubber backing. The color transition from orange to black provides a clear replacement signal.
- Solid orange compound — The entire cross-section is the premium orange compound. Thickness measurements or a scribed wear line serve as the replacement guide.
In either configuration, the orange rubber compound delivers significantly higher abrasion resistance than standard black rubber skirtboard. It is the preferred choice wherever aggressive, abrasive materials — crusite, aggregate, coal, or iron ore — impact the skirting at high velocity.
Orange vs. Black Rubber Skirtboard
Both materials serve the same sealing function, but the compounds are formulated for different duty levels. The table below summarizes the key differences to help you select the right skirtboard for your application.
| Property | Orange Skirtboard | Black Rubber Skirtboard |
|---|---|---|
| Abrasion Resistance | Excellent — premium NR or SBR/NR blend | Good — standard SBR compound |
| Wear Visibility | High — orange-to-black color change | Low — no visual indicator |
| Durometer (Shore A) | 50–65 | 55–70 |
| Typical Service Life | 1.5–2× standard black | Baseline |
| Cost | Higher upfront, lower per-ton cost | Lower upfront |
| Best For | Mining, quarry, high-impact zones | Light to moderate duty conveyor skirting |
For operations that need the visual wear indicator but face lighter abrasion, polyurethane skirtboard offers another alternative with excellent cut and gouge resistance.
Applications for Orange Skirtboard
Orange skirtboard is specified wherever standard black rubber wears out too quickly or where maintenance visibility is a priority. Common applications include:
- Mining operations — Copper, gold, iron ore, and coal handling where sharp, abrasive material impacts the skirting at high speed and volume.
- Quarry and aggregate plants — Crushed stone, gravel, and sand processing where material drop heights create severe wear at loading points.
- High-impact transfer points — Any conveyor-to-conveyor transfer where large lump material strikes the skirting zone, especially on heavy-duty conveyor belt systems.
- Cement and mineral processing — Clinker, limestone, and calcium carbonate handling with fine abrasive dust and high tonnage throughput.
- Ports and bulk terminals — Ship-loading and reclaimer conveyors where extended service life reduces costly maintenance shutdowns.
In all of these environments, the orange wear indicator gives maintenance teams an at-a-glance status check during routine walk-arounds, allowing them to schedule replacements during planned downtime rather than reacting to failures. Pairing orange skirtboard with the right conveyor belt fasteners ensures the entire conveyor system stays running efficiently.

Frequently Asked Questions
Why is skirtboard rubber orange?
The orange color serves as a built-in wear indicator. Orange skirtboard is engineered with a high-visibility compound so maintenance crews can quickly gauge remaining rubber thickness. When the orange surface wears through to the black backing or substrate, the color contrast signals that the skirtboard has reached the end of its service life and needs replacement. This eliminates the need for manual thickness measurements and makes it easy to identify worn sections during routine conveyor inspections.
How long does orange skirtboard last compared to black rubber?
Orange skirtboard typically lasts 1.5 to 2 times longer than standard black rubber skirtboard in abrasive applications. The premium natural rubber or SBR/NR blend compound is formulated specifically for high-abrasion environments, delivering superior wear resistance at conveyor loading and transfer points. Actual service life varies based on material type, drop height, belt speed, and tonnage.
What thickness of orange skirtboard do I need?
Thickness depends on the severity of the application. For standard loading zones, 1/2-inch orange skirtboard is the most common choice. For high-impact mining and quarry applications with large lump-size material, 3/4-inch or 1-inch thickness provides additional wear life. Consider both the material being conveyed and the drop height when selecting thickness. Texas Belting and Supply can help you select the right size for your specific conveyor configuration.
Can orange skirtboard be used with clamp-style skirting systems?
Yes. Orange skirtboard is available in standard widths and thicknesses that fit most clamp-style and bolt-on skirting systems. It can be cut to length on-site and installs the same way as conventional black rubber skirtboard. No special tools or hardware are required. Contact Texas Belting and Supply for cut-to-size strips or full rolls to match your existing skirting hardware.
