Choosing steel wheels

  1. Load: plan on three wheels carrying a four-wheel cart [S2]; steel wheels rated 3,500 lb each then carry about 10,500 lb.
  2. Floor: on steel wheels, ductile iron suits smooth concrete and heavy loads, but is loud and hard on tile and wood.
  3. Heat: among steel wheels, the highest listed range is -45°F to 800°F on ductile iron; check the temperature field on each listing before oven or hot-room use.
