Why Choose CHCS 3/4 Corrugated Conveyor Covers?
Corrugated Rigidity — The CHCS hood assembly is a ¾ corrugated cover and band with 135° coverage. Because the covers are corrugated, they’re more rigid and made from a heavier material than our standard CH smooth series — the right choice for high-vibration conveyors and demanding outdoor duty.
Open-Side Access, No Lifting — CHCS covers are stationary with a standard 45° opening. The open side lets crews inspect or view the material being conveyed and repair, replace, grease, or inspect the idlers without touching the cover assemblies.
Weather Protection — CHCS covers protect the belt, idlers, and conveyed material from the hot sun, wind, snow, rain, and other damaging weather elements — reducing belt wear and keeping material in spec.
Heavy-Duty Galvanized Construction — Standard covers and bands are made from 20-gauge, G-90 corrugated galvanized steel. Assemblies come with heavy-duty galvanized steel mounting clip angles and standard zinc-plated hardware. If heavier gauges are required for loading requirements, RPS can meet them.
Sizes & Configuration
Standard CHCS cover assemblies are made for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″, and 96″ belt widths — custom sizes are also available. Assemblies accommodate 3′ through 5′ idler spacing, with 4′-0″ as the RPS standard. Because RPS manufactures everything to order, custom dimensions can be produced for your specific project.
Open Side or Full Enclosure? CHCS vs. CHCO
Both series share the same 20-gauge G-90 corrugated construction — the difference is coverage and access. The CHCO Series is a full corrugated cover with 180° coverage and hinged, quick-opening access: the pick when maximum enclosure and dust containment come first. The CHCS trades the last quarter of coverage for a permanently open side with a standard 45° opening — crews can walk the line and service idlers without lifting a single cover. If your maintenance schedule has crews at the idlers often, the open side earns its keep every week. Prefer a ¾ cover in smooth steel instead? See the CH75 Series, the ¾ version of our smooth CH covers.
Material Options
| Material Option | Typical Applications | Construction |
|---|---|---|
| Galvanized Steel (standard) | High-vibration bulk handling where open-side idler access is needed. | 20-gauge G-90 corrugated galvanized ¾ cover and band; galvanized clip angles, zinc-plated hardware. |
| Aluminum | Weight-sensitive structures and corrosive atmospheres. | Aluminum cover and band material. |
| Stainless Steel | Corrosive environments and maximum service life. | Stainless steel cover and band material. |
| Painted Galvanized | Facilities with color or coating requirements. | Painted galvanized steel cover and band. |

What to Send for a Quote
Three numbers get you a fast, accurate quote: your belt width, your idler spacing, and the footage to be covered. Add the site conditions — coastal air, chemical exposure, unusual wind loads — and any color or coating requirements, and our team will confirm material, gauge, and accessories for the application. Because every assembly is fabricated to order, retrofit jobs on existing conveyors are routine: covers are built to your structure, regardless of who made the conveyor.

CHCS Series Frequently Asked Questions
What is a 3/4 corrugated conveyor cover?
The CHCS hood assembly is a ¾ corrugated cover and band with 135° coverage. It is stationary with a standard 45° opening, leaving one side of the conveyor permanently open for inspection and idler access.
How is the CHCS different from the CHCO series?
The CHCO is a full corrugated cover with 180° coverage and hinged, quick-opening access. The CHCS covers 135° and is stationary with a standard 45° opening — the open side allows repairing, replacing, greasing, or inspecting the idlers without touching the cover assemblies.
What belt widths does the CHCS series fit?
Standard CHCS cover assemblies are made for 18″, 20″, 24″, 30″, 36″, 42″, 48″, 54″, 60″, 72″, 84″, and 96″ belt widths. Custom sizes are available, and heavier gauges can be supplied where loading requirements demand them.
What idler spacing do CHCS covers accommodate?
Assemblies are made to accommodate 3′ through 5′ idler spacing, with 4′-0″ as the RPS standard.
What material options are available?
Standard covers and bands are 20-gauge, G-90 corrugated galvanized steel with heavy-duty galvanized mounting clip angles and zinc-plated hardware. Optional cover and band materials include aluminum, stainless steel, and painted galvanized steel.
Are CHCS covers BABA compliant?
Yes — RPS conveyor covers are fabricated at our Elgin, Illinois facility and are BABA compliant for federally funded projects. Material sourcing can change, so contact RPS directly to confirm current sourcing for your order.
