We offer tan sandstone step slabs and grey field stone step slabs. The grey ones are a bit more rare but if you catch us at the right time we should have what you need. Around here the locals refer to the grey colored stones as "fieldstone" and the tan/rust colors are typically referred to as "sandstone." the tan stuff is typically thicker and slightly more flat on top. The grey fieldstone steppers are typically thinner at 4-5" thickness. Occasionally we will get lucky and find the grey steppers at full 7" thickness with a perfect flat side. Our steps come in various thicknesses. Please give us a call today to see what we have in stock compared to what you need. Most large tan steppers range from 7-10" thickness. We try to collect and stockpile the stones in piles with matching thickness. Call us for more information. We have everything from small garden steppers to medium size and then mega size steppers. Let our team know your dimensions and we will get it for you.
