Engineered kits · fabricated in Sonora
A kit from SQ Tech is a complete engineered steel building (rigid frames, purlins and girts, roof and wall panels, trim and fasteners), fabricated in Hermosillo, numbered by erection sequence, and delivered with an anchor-bolt plan, erection drawings and a calculation package your engineer of record reviews and stamps. Eight standard footprints are below, each quoted per project.
The plant is about 175 miles (280 km) south of the Nogales–Mariposa crossing, so a kit reaches Arizona by truck. Hermosillo keeps Arizona time (MST, UTC−7, no daylight saving).
Kit sizes
Each footprint below is engineered again for your site's wind, snow and seismic loads, so treat these as starting points, not limits. Pick the closest size, press "Quote this size", and change the eave height or length in the form.

Delivery
Every kit is quoted all three ways, side by side, so you can compare your own carrier and customs broker with ours.
Loaded on your truck at our plant in Hermosillo, Sonora.
At the Nogales crossing; the handover point is named on your quote.
At your job site.
Kit or custom
All three are steel buildings fabricated in a shop and bolted together on site. What changes is how much of the engineering is standard, who erects the building, and how far it can bend to your process.
A kit is a pre-engineered steel building package: frames, purlins and girts, sheeting, trim, fasteners and anchor bolts, cut and drilled to the drawings and shipped for your crew to erect on a foundation you build. The footprints above are kits. You control the labor and the schedule on site; we check the frame for your site's loads.
A custom building is engineered for one project: its spans, bays, eave height, openings, cranes and loads come from your process, not from a standard footprint. A pre-engineered metal building (PEMB) does it with tapered built-up frames and cold-formed secondary framing optimized for the least steel; a conventional building uses hot-rolled beams and columns designed member by member, with the connections detailed in a shop-drawing phase before any steel is cut.
| Factor | Kit | Custom steel building |
|---|---|---|
| Dimensions | Standard footprints | Any width, length and eave height |
| Cranes | Light cranes, designed into the frame | Any capacity, with runway beams and crane columns |
| Expansion | Limited to repeating the kit's bay | Future bays and end walls planned from the start |
| Engineering | Pre-engineered, checked for your site's loads | Project-specific |
| Who erects it | Your crew or a local erector | Your erector in the US; SQ Tech in Sonora |
| Best for | Storage, shops, ag buildings, small warehouses | Manufacturing, logistics and process buildings |
Building in Sonora instead? We build turnkey there, foundations included: Mainland Headwear's 181,000 sq ft (16,805 m²) plant in Agua Prieta is one (project page in Spanish). See manufacturing in Mexico and prefab steel warehouses and PEMB.
| Type | How it is built | Typical use |
|---|---|---|
| Prefab structural steel building | Hot-rolled steel frames with roof and wall sheeting | Industrial, logistics, manufacturing |
| Pre-engineered metal building (PEMB) | Tapered built-up frames with cold-formed purlins and girts | Warehouses, commercial and light industrial |
| Cold-formed (light-gauge) steel | Galvanized cold-formed framing | Small warehouses, ag and residential |
| Modular building | Volumetric units finished in a factory | Offices, classrooms, clinics |
| Container-based building | Modified shipping containers | Temporary offices and site storage |
All modular buildings are prefabricated, but a warehouse is rarely modular: its clear spans and heights need a steel frame, not stacked factory-built units.
Hot-rolled structural steel (ASTM A36 or A572 Gr. 50) carries the long spans, crane loads and seismic demands of industrial buildings, which is why it is the standard frame for warehouses and plants. Cold-formed galvanized sections do the secondary work, purlins and girts, and frame small buildings with short spans. Aluminum frames suit short spans in corrosive or weight-sensitive settings and are rarely the primary frame of an industrial building.

Questions
Primary rigid frames, secondary framing (Z and C purlins and girts, bracing), roof and wall sheeting with trim and fasteners, and anchor bolts, plus erection drawings, the anchor-bolt plan and a calculation package for your engineer of record to review for your permit. Doors and windows ship as specified on your quote.
Yes. Our plant in Hermosillo, Sonora is about 175 miles (280 km) from the Nogales–Mariposa crossing, and every kit is quoted three ways: pickup at the plant (FCA), delivered at the Nogales border, or delivered duty paid (DDP) to your job site. How delivery works.
The matrix on this page lists eight standard footprints, from 30 × 40 ft to 100 × 200 ft. Other widths, lengths and eave heights are engineered to order, and clear spans are quoted per project.
We design to the IBC edition your jurisdiction has adopted, with steel to ANSI/AISC 360-22 (AISC 341-22 where seismic provisions apply) and loads for your site per ASCE 7. The calculation package goes to your engineer of record, who reviews and stamps it for your permit. Codes and wind design, US and Mexico.
Eave height, loads, cladding, doors and the delivery term move the price, so we quote each kit per project. The steel building cost guide publishes structure-only budget ranges by footprint, including 40 × 60 ft, and lists what they exclude.
If you have a US erector or general contractor, a kit keeps the labor in your hands. If the building goes up in Sonora, we build it turnkey, foundations included. The trade-offs are compared on this page; turnkey buildings are on the prefab steel warehouses page.
Engineering and shop drawings come first, for your approval; fabrication follows in stages, by erection sequence. The total depends on size and panel selection, so send your dimensions and we confirm the dates in writing on the quote.
Kit quote
Send the size (width × length × eave), the job-site city and state, and how you want it delivered. If you have an engineer of record, say so: the calculation package goes to them. Hermosillo keeps Arizona time (MST, UTC−7, no daylight saving).
