Modular buildings for San Antonio

Material Handling USA supplies factory-built modular buildings across San Antonio and Bexar County, from Port San Antonio to New Braunfels and Seguin. As an authorized dealer for a leading U.S. modular building manufacturer, we quote, coordinate freight and arrange installation.

Military and secure-site work is a big part of the market here, along with healthcare and manufacturing.

Joint Base San Antonio, which combines Lackland, Randolph, Fort Sam Houston and Camp Bullis, anchors a large defense and cybersecurity sector, alongside a major healthcare industry, manufacturing and logistics along Interstate 35 and Interstate 10. See our in-plant and industrial modular buildings and modular in-plant offices.

San Antonio projects often split between secure federal work and fast-moving commercial sites. On base and cybersecurity campuses, booths and offices are scoped around access control, protection levels and agency review. At Port San Antonio, the Interstate 35 distribution parks and South Side plants, the priority is usually getting supervisors and shipping staff into conditioned space on the floor quickly.

Hospitals in the South Texas Medical Center area use modular rooms for support functions that need to be added without a long construction project inside an occupied campus.

Heat and storm notes for San Antonio

San Antonio has long hot summers, intense sun and heavy rain events with flash flooding. Booths and exterior buildings need cooling sized for heat and solar gain, and pads set with drainage in mind.

See HVAC options and foundation and anchoring options.
