Get to Know KunkelWorks USA

At KunkelWorks USA, we have enjoyed a close and successful partnership with Japan since 2003. We are supported with technical data and practical help in quick and precise Japanese fashion. We can deliver to you anywhere on the US Mainland and soon in Canada. The installation of a prefabricated carport, patio roof, entry gate or garden fence is super easy and everything you need is provided.

Our headquarter is in Saint Cloud, Minnesota. We have dealers in California (Los Angeles, San Diego, San Francisco), Texas (Dallas and Austin), Florida (Fort Lauderdale), Colorado (Denver), and Utah (Salt Lake City), sunny places where our products are most beneficial. For colder places we can provide enclosed covers that can carry snow loads up to 6’- 7” - or solar panels for that matter!

It took many years to get permission from the manufacturer Sankyo Tateyama Inc. to sell their products to the international market. The manufacturer was concerned about customer service, over which they would have no control outside of Japan. Now, 20+ years later, KunkelWorks USA has hundreds of satisfied customers and the STP aluminum products have a stellar reputation in the US market for their beauty, quality and their resilience against sun, rain, hail, snow, salt and time.
