How to Compare Fabric Building Quotes in Canada

The five questions that make quotes comparable

1. What is the cover weight, in g/m², and what material? Cover weight is the single clearest quality spec. Some suppliers quote ounces per square yard — multiply by 33.9 to convert. A "12 oz" polyethylene cover is roughly 407 g/m². The MAX standard is a 750 g/m² PVC cover.

2. Single or double truss? Truss design determines how the frame carries snow and wind. Double truss is the MAX standard on every size. If a quote doesn't say, ask — and get it in writing.

3. What are the engineered ratings? Ask for wind and snow ratings with engineered drawings available for your permit office. MAX buildings are rated over 120 km/h wind and 80 kg/m² snow.

4. What exactly does the warranty cover, and for how long? Cover and frame warranties are separate. Marketing terms like "protection plan" are not warranty terms — read the actual document. MAX's fabric cover warranty is 12 years.

5. What is the delivered, all-in price? Kit price, delivery, and (if wanted) installation, separately. MAX prices are published on every product page; delivery is free within 888 highway km of Edmonton and Toronto and flat-tiered beyond.

Run the numbers yourself

Take any quote you're holding, get the five answers above in writing, and put it beside our published price list or the cost calculator. If another supplier beats us on a like-for-like spec, buy from them — but make sure it's like-for-like. See also: fabric vs quonset huts and the full comparison guide.

Frequently Asked Questions

Why do most fabric building suppliers not publish prices?

Quote-only pricing lets a seller price each buyer differently and makes comparison shopping slow. As of August 4, 2026, the supplier pages we checked (MegaDome's Alberta page, Coverco's Alberta page, fabricbuildings.ca's pricing page) published no dollar figures. MAX publishes every price because a comparable number is the fastest way to win a comparison we believe we win.

How do I compare cover weights between suppliers?

Ask for the fabric weight in grams per square metre and the material. Some suppliers quote ounces per square yard: multiply by 33.9 to get g/m2. Example: a '12 oz' high-density polyethylene cover is about 407 g/m2. The MAX standard cover is 750 g/m2 PVC.

What frame questions should I ask any supplier?

Three: Is the steel galvanized (and how)? Is the truss single or double? What are the engineered wind and snow ratings for my location? MAX's standard build is double-trussed galvanized steel rated over 120 km/h wind and 80 kg/m2 snow, with engineered drawings available.

What should a warranty comparison look at?

Read what is covered and for how long — cover (fabric) warranty and frame warranty are separate items, and marketing phrases like protection plans are not the same as warranty terms. MAX's cover warranty is 12 years; the full terms are on our warranty page.
