CHFG covers are hinged, so they can be quickly and easily opened for inspecting or viewing the material being conveyed. They also allow easy access for repairing, replacing, greasing, or inspecting the idlers — and they protect the belt, idlers, and conveyed material from hot sun, wind, snow, rain, and other damaging weather. Covering the belt also contains fugitive dust and spillage, helping your operation stay ahead of environmental and EPA compliance requirements.

Why Choose Fiberglass Conveyor Belt Covers?
Metal conveyor covers perform well in most environments, but salt, fertilizer, and chemical exposure will eventually attack even galvanized coatings. Fiberglass conveyor belt covers simply do not rust. FRP is inherently resistant to the chlorides, acids, and alkalis found in salt storage, fertilizer handling, and chemical processing facilities, and it stands up to the salt air that shortens the life of steel covers at port terminals and other coastal operations.
Fiberglass is also lighter than comparable steel covers, which makes handling and installation easier for your maintenance crew — especially on elevated conveyors. The white finish reflects heat rather than absorbing it, and unlike painted steel, there is no coating to chip, peel, or touch up over the life of the cover.
Standard Construction
- Covers: white .090″ thick fiberglass (FRP)
- Bands: 12-gauge Type 304 stainless steel (custom molded fiberglass support bands also available)
- Heavy-duty Type 304 stainless steel mounting foot brackets
- Stainless steel retaining bar holds the cover open during maintenance
- Type 304 stainless steel fasteners standard
Every component that touches your conveyor — bands, brackets, retaining bar, and fasteners — is Type 304 stainless steel as standard, so there is no weak link in the assembly for corrosion to find. Thicker fiberglass gauges are available for heavier loading requirements such as snow load or high-wind sites.
Available Sizes
CHFG fiberglass conveyor belt covers are available for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″, and 96″ belt widths, with custom sizes also available. Assemblies accommodate 3′ through 4′ idler spacing, with 4′-0″ as our standard. If required, RPS can cut covers shorter for the special section(s) on your project — transfer points, skirted sections, and other odd-length runs are routine for us.
Because RPS Engineering manufactures everything to order, we can build most custom dimensions your project requires. Not sure what to specify? Send us your belt width, idler spacing, the material you’re conveying, and your site’s environmental conditions, and our design team will recommend the right configuration.
Common Fiberglass CHFG Applications
- Salt mining, storage, and road-salt handling facilities
- Fertilizer production, blending, and distribution terminals
- Chemical processing plants
- Coastal and port terminals exposed to salt air
- Wastewater and other corrosive municipal environments
Made to Order Since 1975
RPS Engineering has manufactured industrial cover systems since 1975. Every set of CHFG fiberglass conveyor belt covers is fabricated to length at our plant outside Chicago from FRP sheet manufactured in the USA, with a 1–2 week turnaround on most custom orders and fast shipping anywhere in the U.S. Material sourcing can change — contact RPS directly to confirm current sourcing and compliance for your project. If fiberglass isn’t the right fit for your site, the same hinged design is available in galvanized steel, aluminum, and stainless steel as our CH Series, because –

CHFG Series Frequently Asked Questions
What are CHFG fiberglass conveyor covers made of?
CHFG covers are white .090″ thick fiberglass reinforced plastic (FRP), with 12-gauge Type 304 stainless steel support bands, stainless steel mounting foot brackets, and Type 304 stainless steel fasteners standard. Custom molded fiberglass support bands are also available.
Are CHFG covers made in the USA?
CHFG covers are fabricated to length at our Elgin, Illinois plant from FRP sheet manufactured in the USA. Material sourcing can change — contact RPS directly to confirm current sourcing and compliance requirements for your project.
When should I choose fiberglass over galvanized steel covers?
Choose FRP where salt, fertilizer, chemicals, or coastal salt air would attack even galvanized coatings — fiberglass conveyor covers do not rust. For most other environments, our galvanized steel series offer excellent service life; the same hinged design is available in galvanized, aluminum, and stainless steel as the CH Series.
What belt widths do CHFG covers fit?
CHFG covers are available for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, and 72″ belt widths, with custom sizes available. Assemblies accommodate 3′ through 4′ idler spacing, with 4′-0″ as the RPS standard, and covers can be cut shorter for special sections.
Do CHFG covers open for maintenance like the metal series?
Yes — CHFG covers are hinged and open quickly for inspecting the belt or the material being conveyed, with a stainless steel retaining bar that holds the cover open while crews repair, replace, grease, or inspect the idlers.
About RPS Engineering
RPS Engineering is a woman owned, WBE certified manufacturer that has produced custom metal covers in Elgin, Illinois since 1975. Every metal cover is built in-house: we cut, punch, and curve each piece to match the exact belt width, channel, or tank dimension it will protect. Our conveyor covers shield belts, idlers, and materials from wind, rain, snow, sun, and dust for aggregate, mining, and industrial customers. Our wastewater covers control odor and protect equipment at municipal and industrial treatment plants nationwide. Product lines include our CH, CH75, CHFG, CHCO, CHCS, and CHLC conveyor cover series along with custom industrial cover capabilities.
