Welcome to Harnois Industries’ web site. We are a greenhouse and shelter manufacturer, dedicated to provide growing and building solutions to customers in North America and the world.

And it all starts with steel. Actually, it starts with over 9 million pounds of it, which we bend, weld and eventually transform into greenhouse and shelter structures.

Since 1956, our horticultural and irrigation division has been providing growers with complete growing solutions, for any kind of crop. We pride ourselves in merging the latest technology in horticulture and agriculture with our keen sense of innovation and design, to create structures and select equipment that can help growers grow healthier, more profitable crops. Anywhere in the world.

Our building division, started in 1999, applies the same innovative approach to offer storage and covering solutions for different applications, such as crop and machinery storage, covering solution for manure pits, solid waste and recycling management, warehousing and shipping docks, road abrasive storage for municipalities and Department of Transportation, and many others.

We now invite you to browse our pages to find out how our products can help you run your business more efficiently, more profitably.
