70′ standard / 80′ Industrial
Ten feet more width comes with a taller profile and a different framing arrangement. See where the steel changes, then choose the space your operation needs.
Inside the cover
Both buildings use trussed steel arches and steel purlins. The 80-wide adds thicker main tube walls, closer frame spacing and the tubular bracing shown below.
Excerpts from the supplied drawing sets, independently enlarged. The 70 view has a length break; the 80 view shows the full 200-foot arrangement. These perspective views are not at a common scale. Tap either drawing to inspect it.
Look at the intersections
Purlins run along the building between its arches. In the 80-wide roof drawing, short tubular braces repeat where these members meet the frames. Larger tubular diagonals brace selected bays. These are separate from the web members inside each trussed arch.
Roof-plan excerpts enlarged for inspection, not to a common scale. The 70 manual identifies its steel-wire arrangement; the 80 drawing shows the tubular arrangement. The complete supplied layout determines the actual brace locations. Cable bracing is a structural system, not a sign that the 70 is incomplete.
Frame spacing changes from approximately 10 feet to 8 feet. At 200 feet long, the compared layouts have 21 and 26 frame positions, including both ends: five more frames on the 80.
Spacing illustration only. The drawing dimensions are 3,050 mm and 2,440 mm. This is not an assembly layout or a load-capacity comparison.
Both compared main-tube designations start at 76 mm. The wall changes from 2.0 to 2.5 mm: a 25% increase in nominal wall thickness. The purlin specification remains 60 × 1.5 mm in the reviewed documents.
Wall thickness is not steel grade, total steel weight or a percentage increase in building strength. We use the actual metric wall thickness rather than an ambiguous gauge number.

| Main arch tube designation | 76 × 2.0 mm | 76 × 2.5 mm |
| Nominal wall thickness | 2.0 mm | 2.5 mm |

| Purlin tube specification | 60 × 1.5 mm | 60 × 1.5 mm |
| Bracing shown | Steel-wire bracing in the documented arrangement | Repeated short roof connection braces; tubular diagonals in selected bays |

Standard 70′ / 28′-peak configuration versus 80′ / 37′-peak Industrial. The 70′ / 32′-peak option is separate. Nominal dimensions and drawing opening references do not guarantee usable interior clearances. Both have the same published 12-year prorated fabric and 2-year manufacturing warranty, subject to written terms.
Published prices
| Same length. Same scope. | 70′ standard | 80′ Industrial |
|---|---|---|
| Nominal footprint | 14,000 sq ft | 16,000 sq ft |
| Building kit | $83,888 | $160,888 |

| Installation base | $43,000 | $69,000 |
| Installed from | $126,888 | $229,888 |
$77,000 more for the 80′ kit, with 2,000 more nominal square feet and the taller Industrial configuration.
Installed from = building kit + published installation base, assuming an install-ready site. Site preparation, site-specific engineering, tax, and equipment, travel or lodging supplied by MAX are additional where applicable. Confirm each item in your quote.
MAX arranges delivery. Delivery is included within 888 highway km of the hub supplying your order. Unloading is the customer’s responsibility unless your written quote states otherwise. Check delivery scope.
If equipment, access aisles, storage and usable clearances work within the 70-wide configuration, its lower purchase price can make it the better choice. If floor area is the constraint, compare adding length where your site allows it.
Plan the 70-wide layoutThe extra width and taller profile may solve an access or operating-space requirement. Measure the equipment and how you use it. The nominal 37-foot peak does not mean that height is available at the doorway or across the floor.
Plan the 80-wide layoutThe reviewed door references are approximately 18 × 16 feet for 70-wide and 18 × 18 feet for 80-wide. The entrance gets taller, not wider. Confirm the actual clear opening for your order.
Independently enlarged source views. Drawing height references differ from rounded sales dimensions; confirm current supplied drawings and usable clearances. These views are not equipment-fit guarantees.
Moving from 70 to 80 feet adds about 14.3% nominal floor area at the same length. It also changes the building’s height, frame spacing, wall thickness, bracing arrangement and cover specification. The quoted product is a different configuration.
A wider and taller structure changes the engineering problem. Its complete design includes the arches, purlins, braces, connections, foundations and site loads. Those component differences help explain the product; they do not calculate its retail price or prove a comparative load rating.
No. It describes nominal main-tube wall thickness only. Building capacity depends on the complete design and applicable site requirements.
No. It uses its documented steel-wire bracing arrangement. The 80 uses the different tubular arrangement shown here. Compare the complete configuration for your project.
The reviewed drawings show repeated short braces at roof purlin connections. Use the actual supplied connection schedule to confirm each location; these excerpts do not establish a universal count.
Installation is a separate service. Supplied manufacturer drawings are not provincially stamped site-specific engineering. Confirm your installation scope, foundation, local requirements and any additional engineering in your project quote.
Yes. That is a separate configuration and is outside the standard 70/80 structural comparison here. See the 70 × 200 × 32 and request its specific clearances and documents.
Tell us your location, what needs to fit, equipment dimensions and intended timing. We’ll help compare the appropriate building and complete project scope.
Source review: 2026-09-24. Drawing excerpts: standard 70-wide family arrangement and 80 × 200 Industrial arrangement; steel-wire identification checked against the 70 × 200 assembly manual. The diagrams explain components, not erection methods. Confirm the current supplied configuration before ordering. Engineering notes.
