Cor-ten Steel
All the pavers are precast concrete by Stepstone 24 x 24. The ones on the raised patio are called "Dekstone" and they are supported by wood framing (http://www.dekstone.com/). They are made of higher psi concrete and are reinforced with steel mesh to prevent cracking. The pavers at grade are the standard CalArc pavers by Stepstone (http://www.stepstoneinc.com/calarc-pavers.htm). Stepstone pavers come in many colors, sizes and with more or less aggregate (slag).
Yes, these planters were welded in place on-site. They were welded and anchored into the ground using recycled "T" stakes from fencing that was taken down on the same site. Dowels were strategically placed into the concrete, and the steel framework was then welded to the dowels holding everything in place.
On Spot Welding in Novato did all of our corten steel work and are currently making our front gate. They are located in Bel Marin Keys. They do great work!
