Industries Harnois

Harnois Industries, founded in 1965, has completed over 20,000 projects worldwide. Located in the most northern part of North America, we specialize in fabric buildings and commercial greenhouses designed to endure harsh climates.

Our fabric covered buildings offer quick, cost-effective storage solutions for industrial equipment and bulk materials. They protect from the elements, extending equipment life and keeping goods dry and accessible. These structures meet municipal standards and provide ample space for machinery like loaders, excavators, trailers, and trucks.

Harnois greenhouses cater to commercial farmers, floriculture, and nurseries. Built to withstand high wind and snow loads, they support year-round cultivation and expanding growing spaces. Our professional greenhouses ensure a stable environment for crops, enhancing productivity and efficiency.

We pride ourselves on delivering durable, flexible structures that meet the specific needs of various industries. From industrial storage to agricultural use, our fabric buildings and greenhouses provide reliable and innovative solutions.
