Supreme Rubber on aluminum pairs a premium soft-rubber tread with a lightweight aluminum core. The rubber gives a quiet, cushioned, non-marking roll; the aluminum core keeps the wheel light and corrosion-resistant while still carrying up to 800 lb. A 6 to 8 inch wheel built for finished floors where noise and load both matter.
A rubber tread can sit on several core materials. Aluminum is the one that stays light and won't rust, which matters for two reasons: lighter wheels are easier on the operator over a long shift, and corrosion resistance suits wash-down-adjacent and humidity-prone environments. Paired with the Supreme Rubber compound, you get a wheel that rolls quiet, protects the floor, resists corrosion, and still reaches 800 lb per wheel — a combination a steel or iron core can't match at the same weight.
Institutional and hospital equipment, food-service carts, lab trolleys, and any finished-floor application where a quiet, non-marking roll is required but the load is real. The 6, 7, and 8 inch sizes cover most mid-weight cart and equipment needs in that range.
