HIGH FORMAT® + Rosetta Hardscapes

Who we are: Explaining the relationship between HIGH FORMAT® and Rosetta Hardscapes

Let’s start with the big picture. Over the course of three generations, the Manthei family has built a diverse group of companies spanning concrete manufacturing, construction products and services, forestry products, and real estate. Today, these businesses are collectively known as the Manthei Group.

Both HIGH FORMAT® and Rosetta Hardscapes are part of the Manthei Group; however, each is a distinct business with its own purpose, leadership, and team.

Rosetta Hardscapes

Rosetta Hardscapes develops advanced wetcast concrete technology and licenses it to more than 30 producers worldwide. Each licensed producer operates within a specific geographic region, manufacturing the same popular products you know and love—from Outcropping and Grand Ledge to Grand Flagstone and Dimensional Flagstone.

Rosetta Hardscapes also provides comprehensive technical, product, and sales support across all territories. As a result, you’ll often see marketing materials that feature both Rosetta Hardscapes and an individual producer working together.

When a homeowner or contractor purchases a product like Kodah Wall blocks from a local dealer, that dealer is sourcing the product from a regional producer responsible for that territory. While the product designs remain consistent, each producer offers its own unique color selections tailored to local preferences and regional demand.

HIGH FORMAT®

In 2008, HIGH FORMAT® became the first original producer of Rosetta Hardscapes, operating under the name “Rosetta of Michigan”.

In 2020, we rebranded as HIGH FORMAT® to clearly distinguish ourselves as a separate entity from Rosetta Hardscapes. This shift gave us the flexibility to expand our product offerings beyond wetcast concrete. Today, we continue to manufacture walls, steps, and pavers using Rosetta Hardscapes technology, while also offering a full line of large-format, ultra-high-performance concrete slabs as well as an extensive selection of travertine and marble natural stone products.

HIGH FORMAT’s sales network spans Michigan, Wisconsin, Ohio, and parts of Indiana and Illinois.
