2026 RPS EngineeringWhy Choose CHCO Corrugated Conveyor Belt Covers?
Corrugated Rigidity The CHCO hood assembly is a full corrugated cover and band with 180° coverage. Because the covers are corrugated, they’re more rigid than smooth covers — the right choice for cement plants, quarries, and high-vibration environments where structural stiffness matters.
Quick-Opening Hinged Access Covers are hinged and quick opening for inspecting or viewing the material being conveyed, and for ease of repairing, replacing, greasing, or inspecting the idlers.
Weather Protection CHCO 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 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 CHCO 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.
Where CHCO Covers Are Used
Corrugated covers earn their keep where vibration, impact, and abrasive dust punish lighter covers: cement plants, rock quarries, aggregate operations, and bulk material terminals. The perpendicular corrugations stiffen the hood against the constant vibration of heavy conveyors, and the full 180° enclosure keeps wind-blown dust down and weather off the belt. If your line runs outdoors through freeze-thaw seasons or carries material that can’t take on moisture, a full corrugated cover is usually the most durable choice in the RPS lineup.
Dust Control & Compliance
Enclosing a conveyor is one of the most effective ways to cut fugitive dust at its source. Covered belts help operations manage airborne dust in line with OSHA combustible dust guidance and, at mining and aggregate sites, MSHA requirements — while also reducing material loss in transport, which pays for covers over time. If dust or spillage complaints brought you here, tell us about the site conditions and we’ll recommend the right coverage and accessories, including wind guards and skirting from our parts line.

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.

CHCO Series Frequently Asked Questions
How is the CHCO different from the CH smooth series?
CHCO covers and bands are corrugated, which makes them more rigid than smooth covers — the right choice for cement plants, quarries, and high-vibration environments. Covers and bands are 20-gauge G-90 galvanized steel, and like the CH series they’re hinged for quick opening and inspection.
What belt widths does the CHCO series fit?
Standard CHCO 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 CHCO 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 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 CHCO 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.
