8,000 sq ft · Engineered Kit · Fabricated in Sonora, Mexico
An 80×100 steel building kit gives you 8,000 sq ft in a squarer footprint that suits assembly floors, hangars and packing sheds where you want an open 80 ft width more than a long building. This is the size a Guaymas workshop owner and a Tennessee storage business both quoted with us recently — one erected in Sonora, one shipped across the border.

Weights and truckloads are planning figures for a conventional pre-engineered building; the quote is engineered to your site's wind, snow and seismic loads and your opening layout.
80 ft is the practical limit before clear-span frames get heavy. A center column line (2 spans of 40 ft) typically reduces frame steel by a noticeable share — worth it unless the floor must be fully open.
Hangar use changes the gable-end design entirely (the end frame becomes a header beam); tell us the door type in the first message.
At 8,000 sq ft, roof drainage and snow/rain loads matter: Sonora and Arizona sites design for wind and rain intensity; northern US sites add ground-snow load. We engineer to the site, not a generic load.
Clear-span rigid frame (80 ft) or 2-span modular with a center column line. Shop-welded, primed, match-marked by erection sequence.
Z/C purlins and girts, bracing, framed openings, roof and wall sheeting, trim and fasteners.
Erection drawings, anchor-bolt plan and the calculation package for your engineer of record to stamp.
FCA plant, delivered at the Nogales border, or DDP to your site. A 80×100 is 2 flatbeds.
