Structure Options

We don’t bend any steel before we get an order. This allows us to customize our products for your structure requirements. We use 7 different lengths of steel, and can interchange the way we bend them to give you the same shape, with less height, or slightly different width if that’s what you require. You can see more about the profile shapes and heights on our profile page

We have engineered drawings for our standard buildings to help you get a building permit. It is impossible to have them for all the variations we offer though, but we do have them for most of our standard buildings. Please let us know if this is something you will require.

We have provided sample prices on each of these pages to give you a starting point, but have any width available from 10-36′, and can go any length you require. We’ve done them up to 300′ long! Typically we do structures at 3′ and 4′ spacing between hoops, but can go 2′ spacing for extremely high snow areas and 6′ spacing if it will be left uncovered in the winter.

Our structures have a standard Gothic Profile that comes to a peak, to shed snow more efficiently. Our structures are Canadian built for Canadian seasons. We add wind braces to ensure stability in windy areas, and can give you other tips for winter maintenance and snow if you are especially concerned.

We also offer our High Profile structures, which give around 2′ more clearance than our regular standard Gothic profile. Up to 20′ wide our high profile uses 1″x2″ steel, and we offer a heavy high profile option that is 20′ wide and uses 1″x3″ steel. 24′ and wider uses 1″x3″ steel as standard.

We have also created our Cathedral Series, which is our standard gothic arch flipped around, to give more usable height, with less floor space (for RVs as an example). see here. It is more susceptible to wind, because of the straight sidewalls. No snow stays on this shape at all, unless there has first been a wet slushy rain/snow, and then a freeze. This style is available in widths of 20′, 18′, 16′ and 14′.

We also have our Space Saver series, which also has straight side walls, with more of a peak. This style is not recommended for high snow or wind areas. It is particularly good for garages, as you are able to have more space for opening car doors and storage with less floor space. This is available in widths of 10′, 12′ and 16′.

We have been known to make our version of an igloo, and flying structures lifted up onto apartment buildings to help construction (see our Unique Uses page!). We welcome your unique challenge and look forward to helping you find your shelter solution!

Igloo Round Structures

 We have a unique structure that we have started offering more often. It is a round dome structure, with our standard hoops around a circular ridge piece. We have taken to calling this our “Canadian Igloo” Structure. Plastic is put on in separate pieces so it’s not for the new greenhouse assembler. We have them being used for everything from seminar areas to storage, whatever you would like a unique application for!
