Our Products

Rockfaced Treads

  • Stone widths available from 6" to 24" in 2" increments.
  • Standard lengths from 4' to 10' in 1' increments. Lengths over 10’ are available for an extra charge.
  • Thickness is 2" (± 1/8" is standard)
  • Color is light to dark shades or gray
  • Weight is 25 pounds per square foot.
  • Special Note: Buff stone is not recommended for exterior tread use as it normally has only half of the crushing strength and twice the water absorption of hard gray stone.

Elliott Stone Company foresaw the demand for a durable, economical and attractive material to be used for steep treads, mantel, coping and hearths. We selected gray limestone for this use because of its superior hardness and lower water absorption compared to other colors of Indiana limestone. Elliott Stone Company Rockfaced Treads are sawn on six sides then a rockface is added. Uniform sizes and thickness makes Elliott Stone Rockfaced Treads easy and efficient to install. Being a product of nature, you should expect some variation in color from piece to piece.

Over the past 30 years, hundreds of tons of Rockfaced Treads have graced fine architecture throughout the Eastern seaboard. First commercially quarried in 1827, limestone from the hills of Southern Indiana has been used in familiar American landmarks such as the Empire State Building, the Pentagon, The National Cathedral, and a host of other building s monuments, schools, churches, and homes.
