Tanzite is a man-made stone (porcelain-like) created under extreme heat and pressure, engineered specifically for long-term outdoor performance.

What is the difference between the Appalachian and Rainier collections?

Appalachian installs like composite decking using hidden clips (not waterproof). Rainier is a free-floating system designed to be waterproof when installed over a subfloor.

Do the stones heat up in the sun?

All materials warm up, but Tanzite typically heats more slowly and doesn’t reach the same temperatures as similar-colour composites. Choose lighter colours for the coolest surface.

What warranty does Tanzite offer?

Tanzite advertises a limited lifetime warranty for its stone decking. Installation defects (e.g., lippage) are excluded—see the warranty page for details.

Where do orders ship from and how long does shipping take?

US and Canadian orders ship from Indianapolis, Indiana (typical delivery 1–6 days depending on location). European orders ship from Spain (about 3–7 days).

Appalachian Standard Edge Boards (Version 2)

Standard Edge Boards are used on the exposed perimeter of the deck/stairs, as they have a finished top surface and front edge to give a clean finish to the deck's edge. The front side has an internal groove, which is held down using either the Starter Clip or the Edge Clip. The back side is grooved, and held down using the groove clip. (the groove clip can hold three boards at the same time)

Easy to work with

Easy to work with. We are building our second deck with this product today!

Perfect finishing touch!

Love the look and the ease of attaching the edge boards…

Deck one framing of a two deck project complete.

Just finished phase one deck framing of a two deck project and stated installing the stone decking. Absolutely love the way it is turning out and it looks great. Both deck will not be complete for about 2 months.

The look is great.

Again I love the look. The colours picked go great with the brick.
