Metal Caster wheels or Steel Caster Wheels are commonly used in many Vintage Applications and DIY Projects where one may want a vintage or industrial style caster to compliment their furniture or project. Each caster holds 700 lbs capacity making a Set of 4 able to withstand up to 2,800 lbs. Steel wheels should not be used on Hardwood Floors, Tile, or Bamboo Floors as they could leave marks or tear up softer flooring. We always recommend steel wheels to be used on smooth concrete surfaces or a surface you don't mind possibly scratching.
