20,000 sq ft · Engineered Kit · Fabricated in Sonora, Mexico
A 100×200 steel building kit — 20,000 sq ft — is where owner-builders stop and developers start. It is the smallest footprint that behaves like a distribution center: a full dock wall, a 28 ft clear height for 4-high racking and a 200 ft run that fits a production line end to end. We quote it as a kit for US job sites and as a turnkey building anywhere in Sonora.

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.
At 20,000 sq ft the freight is 3–5 truckloads, so delivered-at-border (Nogales) pricing versus DDP to the job site is the first number to compare — the border option lets you use your own carrier for the US leg.
Crane bays (5–10 t) are common at this size; the runway beams and crane columns are part of the kit design and must be fixed before shop drawings.
Buildings this size in Sonora are typically delivered turnkey in a 4–6 month program including foundations and erection; the kit-only path is for owners with their own erector.
2-span modular (2 × 50 ft) or clear-span 100 ft with heavy rigid frames. 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 100×200 is 3 to 5 flatbeds.
