Finding Concrete Tree Rings with the Mow Strip on the Inside: A Supplier Guide

You want curved concrete tree rings where the mow strip (flat edge) faces inward and the "bump" faces out—so you can create a zigzag pattern around trees, not just circles. Standard rings have the bump inside, which won't work for your design.

Where to Look

• Quickcrete (Southern California) – Commercial supplier of tree grates and rings. Website. Shipping to Alberta may be cost-prohibitive.
• Search terms for Google: "concrete tree grate Canada," "precast concrete tree ring Alberta," "tree surround pavers Canada."
• Metal alternatives: Neenah Foundry (nfco.com), Ironsmith (ironsmith.biz) – may offer concrete or know regional suppliers.

Local Strategy

1. Call Alberta precast concrete manufacturers—many make park and streetscape products.
2. Check with municipal public works; they often have approved vendor lists.
3. Ask landscape contractors who do commercial work—they source these regularly.

Custom shapes (zigzag) may require a mold. If no stock product exists, a local precast shop can cast to your template.
