Four Ways to Use a Mexican Steel Building Plant
US owners & general contractors
Engineered steel building kits — 30×40 to 100,000+ sq ft — delivered to your site for your erector. The most common request: a 40×60 shop or a 50×100 warehouse shipped to Texas or Arizona.
Steel building kitsUS steel fabricators & erectors
Overflow and contract fabrication from your approved shop drawings: primary frames, joists, plate work and misc steel when your shop is at capacity or your bid needs a lower fabricated cost.
Contract fabricationCompanies leaving Asian suppliers
Buildings, kits and components you used to import from China, re-engineered and manufactured 175 miles from Arizona. Same designs, trucked instead of shipped, without the container lead times.
Manufacturers opening a plant in Mexico
Turnkey pre-engineered buildings for nearshoring operations in Sonora: design, fabrication, foundations, erection and permits with an English-speaking project team.
Manufacture in MexicoMoving Your Steel Building Supply Out of Asia
A growing share of our US inquiries starts the same way: "We currently buy our buildings — or our purlins, tube trusses and sheeting — from China, and with tariffs and lead times we want to manufacture in North America." The building does not have to change. Send us the supplier's drawings or spec sheet; we re-engineer to the same geometry and to the loads your engineer of record specifies, manufacture it in Sonora, and truck it to the border. Kits can be crated by building so you pull them from your own warehouse exactly as you do today.
| Sourced from China | Manufactured by SQ Tech in Sonora | |
|---|---|---|
| Transit to a US job site | 4–8 weeks ocean + port + drayage | 1–3 days by truck from the Nogales border |
| Minimum order | Full container(s) | One flatbed — no container math |
| Engineering standard | Supplier's default; re-stamp often required | Designed to IBC / ASCE 7 loads you specify, calc package for your EOR |
| Design changes after PO | Weeks, by email, across 13+ time zones | Same day, same time zone, on the phone with the engineer |
| Origin documents | Chinese origin | Mexican origin with mill certs and USMCA certification where qualifying |
| Damage & shortages | Resolved after a second ocean crossing | Replacement pieces trucked in days |
| Payment & currency | LC / wire in advance | USD wire, staged with fabrication milestones |
Days, not months
Hermosillo to the Nogales–Mariposa crossing is a same-day truck run. Most US Southwest sites are one to three days from the border.
Origin you can document
Mexican-origin steel products with mill certificates and USMCA certification of origin where the product qualifies. Confirm duty treatment for your HTS code with your broker — we supply the paperwork.
Your design, our engineering
Same profiles and geometry, re-checked to IBC / ASCE 7. You receive a calculation package for your EOR instead of an unstamped factory drawing.
