Industrial Series Reference

Engineering Notes — Why 80′ Clear-Span Costs What It Costs

A plain-English reference for procurement buyers, ops managers, and anyone evaluating the Industrial Series price. We publish prices openly on every building we sell. Here we publish the engineering rationale behind them. Five-minute read. No hidden math.

Bottom line up front: The Industrial Series uses bigger steel, a heavier cover, and tighter truss spacing. Installation is offered as a separate service and quoted on inquiry. The price reflects the engineering, not a markup. The Commercial Series is roughly flat at ~$5.50/sq ft across all 18 sizes; the Industrial Series isn’t on that curve, and this page explains why.

Why this page exists

MAX publishes every price — Commercial and Industrial. Most of our competitors hide Industrial pricing behind quote forms because the per-square-foot number looks different from what a buyer expects after pricing a Commercial-class building. We don’t hide it. We explain it.

If you’ve priced an 80-foot fabric building somewhere else and gotten a number that surprised you, this page is the reason. If you’re a procurement officer evaluating a MAX Industrial quote against another supplier, this is the rationale for the spec we ship and the price it carries. Five-minute read. No marketing.

1. The span problem

When you make a clear-span fabric building wider, the structural demand on the truss grows faster than the size step. A 14% wider span doesn’t ask the steel for 14% more strength — it asks for substantially more, because the load has farther to travel before reaching the foundation, and the truss has more length to flex over.

That’s why the Industrial truss isn’t 14% beefier than the Commercial truss. It’s substantially beefier. The diameter and wall thickness change is what’s in Section 3 below — both measurable with a tape measure on a delivered building.

2. The peak problem

Going from a 28-foot Commercial peak to a 37-foot Industrial peak adds two compounding effects at once.

First: more vertical surface for wind to push against — a taller building is a bigger sail. Second: a longer lever arm between that surface and the foundation. The frame has to be stiffer to hold its shape under wind cycling, not just stronger to resist the load.

Snow loading at the peak adds a similar effect. Snow accumulates on the higher portion of the truss and the structural path to ground is longer. The frame needs the stiffness to stay within deflection limits at the larger peak — and the visible flex of a building that’s deflecting too much is bad for cover life and bad for the buyer’s confidence in the structure.

The geometric upside: the same steeper peak that asks more of the steel also sheds Canadian snow aggressively before it can stack at the apex. The 21-foot peak zone above the 16-foot sidewall is doing the snow-shedding work that flatter, lower-peak buildings can’t.

The Commercial Series solves these problems for spans up to 70 feet and peaks up to 28 feet. Beyond that, the engineering changes character. The Industrial Series is what changes character looks like in steel.

3. What changes in the steel

Two specific dimensions on the main frame tube step up between the Commercial and Industrial Series — diameter and wall thickness. Both are measurable, both are on the spec sheet, and both are what you’re paying for at the larger sizes.

Spec Commercial Series Industrial Series
Frame tube diameter 48 mm 76 mm (oval cross-section)
Frame tube wall thickness 1.5 mm 2.5 mm
Purlin spec 48 mm × 1.5 mm 60 mm × 1.5 mm · 17 groups
Cross-bracing within each truss Double-truss standard 45-degree solid-tube cross-bracing
Truss spacing on centre 10 ft (3.05 m) 8 ft (2.44 m) · 8.33 ft (2.54 m) on the 80×100 by design
Frame finish Hot-dipped galvanized steel Hot-dipped galvanized steel
Truss design Double-Trussed Standard Double-Trussed Standard

What this means in plain English

The Industrial truss is a meaningfully larger pipe with meaningfully thicker walls. If you imagine pushing on the centre of a horizontal pipe, a thicker, larger pipe bends less under the same load. The Industrial truss resists bending and buckling much better than the Commercial truss — which is what allows it to span 80 feet at 37 feet of peak without flexing in ways the cover or foundation wouldn’t tolerate.

We don’t quote a precise multiplier on the structural improvement here. The exact number depends on tube alloy, end conditions, and the specific load case being analyzed — and the buyer doesn’t need a multiplier. The buyer needs the actual measured specs, which are in the table above and on every Industrial product page.

The 45-degree solid-tube cross-bracing

Every truss on the Industrial Series is two parallel oval tubes joined by 45-degree solid-tube cross-bracing. That triangulated geometry is what makes a truss stronger than the same amount of steel laid out as separate parallel tubes. Plain-language version: the cross-bracing turns local bending forces (which steel doesn’t handle as well) into axial tension and compression forces (which steel handles best). Triangles don’t flex; rectangles do. The 45-degree pattern is what keeps the truss honest under load.

Why truss spacing also tightens

On the Commercial Series, trusses sit 10 feet apart. On the Industrial, they sit 8 feet apart on most sizes — and 8.33 feet apart on the 80×100 by design (100′ ÷ 12 truss spaces). Closer spacing distributes roof loads (wind, snow, cover tension) across more frames per foot of building length. Each truss carries less load. That’s part of how the structural engineering balances out at the larger span.

4. Why the cover steps up to 900 g/m²

750 g/m² PVC is the heaviest standard cover in the fabric building category and is the right answer for the vast majority of applications. We move to 900 g/m² on the Industrial Series for three specific reasons:

For a farm, a fleet yard, or a contractor’s storage building, 750g is the right answer and 900g would be money spent on protection the application doesn’t need. For industrial use, the application punishes the cover enough that the heavier fabric earns its weight back in service life.

5. Why the price-per-square-foot looks different

The MAX Commercial Series is roughly flat per square foot across all 18 sizes. From the smallest at $5,888 to the largest at $79,888, the per-square-foot cost stays in a tight band. That flatness is itself a feature of the Commercial design — the engineering scales linearly with size up to 70 feet of span and 28 feet of peak, so the price scales linearly too.

The Industrial Series isn’t on that curve. The steel is a different class of engineering (see Section 3), and the cover is heavier. Neither of those step-ups is a linear extension of the Commercial pricing curve.

What that means in practice: if you compute a Commercial per-square-foot price and extend it linearly to 80×120 or 80×200, you’ll arrive at a number that’s lower than the Industrial price. That difference is real, and it’s the engineering doing its work. We publish the Industrial price openly so that the math, the engineering, and the value of the buy line up where the buyer can see them.

What you’re paying for

What is and isn’t in the published Industrial price

Included on the published price: cover, frame, hardware, anchoring, and delivery — the building itself. There are no upgrade fees and no surprise add-ons for what makes up the building.

Quoted separately: installation. The Industrial Series is not sold as a DIY kit — install at this scale is a crew job, and crew cost varies materially by site location, access, and conditions. We provide installation through MAX-vetted crews and quote it on inquiry.

What the price does not include — same transparency, both directions

6. How to think about the value

If you’re comparing an Industrial Series price against a metal-building or conventional-build alternative, the right comparison is total cost of ownership over the service life of the building, not initial-build cost.

Honest scope helps procurement evaluate against other suppliers. Here’s what MAX Industrial does not currently include:

8. The bottom line

We publish prices on every building in our catalogue — Commercial and Industrial. We tell you what’s included, what isn’t, what we sell, and what we don’t.

The Industrial Series price is higher per square foot than the Commercial line because the steel, the cover, and the install are all stepped up. Bigger pipe, thicker walls, 45-degree cross-bracing, tighter spacing, heavier fabric, crew install. The price is the receipt for that engineering, not a markup.

If you’re comparing MAX against a competitor whose Industrial pricing is hidden behind a quote form, ask them to publish what they’re shipping. If they can’t, that’s information.
