Where are you looking to build?

We are headquartered in Mineola, Texas with Project Managers in the East Texas and North DFW area. Therefore, we are able to offer concrete-building-erect services in and around these areas. The following map highlights the counties where we can provide this service.

If you are looking to build a steel building outside our service area, we can manufacture and ship a customized building kit to be erected by a local contractor of your choice. 

(See our Building Only page for more information on a pre-engineered bolt-up steel building.)

We can provide the metal shell, but all interior and wood finish out work will have to be completed by another contractor.

We've found 3 ways you can get the most value out of a steel building with living quarters. Click the button below to find out how!


It doesn’t have to be stressful. Choose Southwest Steel Buildings and build with confidence!

I’m very picky on everything. The reason I went with Southwest was Johnny. He cared about this building the same way I cared about it.
