Is maroon polyurethane more UV resistant?

Maroon polyurethane compounds are often selected for improved UV resistance compared to standard polyurethane compounds, but UV performance is compound-dependent. If UV exposure is important, confirm the specific tread compound used in the SKU.

Which wheel diameter should I choose: 4, 5, 6, or 8 inch?

Larger wheels generally roll easier and reduce push force over seams, thresholds, and debris. Choose the largest wheel diameter that fits your height and clearance requirements.

Q: What are maroon polyurethane on gray polyolefin wheels used for?

They are commonly used for carts and equipment where quiet rolling, floor protection, and a non-corrosive core are desired—often in retail, medical, labs, institutional, and general industrial environments.

Maroon Polyurethane on Gray Polyolefin Wheels

NON-CORROSIVE • QUIET • UV-TOUGH (COMPOUND DEPENDENT)

This collection features maroon polyurethane treads molded/cast on a gray polyolefin core. It’s a popular spec when you want quiet rolling, floor protection, and a non-corrosive core that won’t rust-stain floors or equipment.

UV note (important): In many industrial caster lines, maroon polyurethane compounds are selected for improved UV resistance versus standard polyurethane colors due to stabilizers/additives in the compound. Actual UV performance is compound-dependent—if your wheels live outdoors or under UV sanitization, we can confirm the best tread compound for your exposure.

Choose Wheel Diameter

4" Maroon PU on Gray Polyolefin Compact height • clean floors • carts and equipment 5" Maroon PU on Gray Polyolefin Best all-around • common in medical + institutional carts 6" Maroon PU on Gray Polyolefin Better roll-over • longer routes • thresholds 8" Maroon PU on Gray Polyolefin Maximum roll-over • mixed-surface routes

Standard Performance Envelope

Maroon polyurethane on gray polyolefin wheels use a polyurethane tread on a non-corrosive polyolefin core. Designed for quiet rolling, floor protection, and corrosion avoidance. Maroon compounds are often chosen for improved UV resistance (compound dependent). Available in 4, 5, 6, and 8 inch wheel diameters.

Wheel Diameters: 4"–8" (by sub-collection)
Tread: Polyurethane (quiet, abrasion resistant, floor-friendly)
Core: Polyolefin (lightweight, non-corrosive)
Use Cases: Retail carts/fixtures, medical equipment, labs, institutional carts, general industrial equipment
Environment: Great where rust staining is unacceptable; good around moisture (verify chemicals)
Capacity: Strong load ratings (series dependent—verify per SKU)

Best-fit buyer: If you want polyurethane performance but prefer a non-rusting, lighter-weight core for healthcare, retail, labs, and facilities carts—this is one of the most reliable “standardize it” wheel builds.

Engineering & Purchasing Guidance

Why polyolefin core vs iron/aluminum core

Non-corrosive: eliminates rust staining and reduces maintenance in wet/cleaning environments.
Lighter: reduces overall caster weight versus many metal-core builds.
Practical: great when you don’t need the extra mass of an iron core.

UV exposure / outdoor use: what to know

Polyurethane performance under UV depends on the exact tread compound. Maroon polyurethane is commonly specified where buyers want improved UV stability versus “standard” compounds.

Outdoor sun: choose a tread compound intended for UV exposure and confirm expected life.
UV sanitization: tell us the UV method/cycle so we can recommend the best compound.

Note: If UV is a major driver, we can validate the exact compound used in the SKUs you’re considering.

Where these are commonly used

Retail: stock carts, fixtures, in-store handling
Medical: carts and equipment where noise + floor protection matter
Labs & facilities: corrosion avoidance and clean routing
General industrial: carts/racks on sealed concrete and shop floors

FAQs

Is this non-marking? Many polyurethane compounds are non-marking, but compounds vary—verify if marking risk is critical.
Which diameter should I pick? Larger wheels reduce push force and improve roll-over; choose the largest that fits height/clearance.
Can you match a replacement? Yes—share wheel diameter/width, bearing type, axle size, and photos.
