Canadians are used to some snow, but 67 inches (170 cm that is) in seven days in Newfoundland is what even the team of Canadian manufacturer Harnois calls exceptional. "We're happy to report that our Ovaltech freestanding greenhouse successfully withstood this", says Vincent Douville, Harnois.

Tube design
"At the heart of our Ovaltech's exceptional performance is our proprietary oval tube design that's pre-drilled", he explains. "Unlike conventional round tubing, the oval profile distributes structural loads more efficiently across the arch, providing superior resistance to the lateral and vertical forces generated by heavy snow accumulation. This geometry is not merely aesthetic; it is a core engineering advantage."
Equally critical is the custom arch spacing determined for every project. "Our engineering team calculates the distance between each arch specifically for the climatic conditions, intended crop loads, and structural requirements of each individual site. The result is a structure that offers the ultimate ratio steel/light transmission", says Vincent.
Engineered for each location, stamped by experts
Harnois greenhouses are designed and engineered to handle the unique climatic conditions of the installation site, accounting for wind, snow, and crop loads. The structural plans are stamped and certified by Harnois' team of expert engineers, ensuring full compliance with regional engineering standards.

What's at stake for growers
"For growers operating in Canada's climates, a greenhouse collapse is not merely a financial setback: it can mean the total loss of a season's crops, disruption to supply chains, and damage that takes months to recover from", Vincent concludes. "Harnois Greenhouses' engineering-first approach is designed to eliminate that risk, giving growers the confidence to operate year-round, even through Newfoundland-scale storms."
