Frequently Asked Questions
Global Buyer Questions Regarding Our Facilities
Where are ROXBOX manufacturing facilities located?
ROXBOX operates a 40,000 square foot modular manufacturing facility in Houston, Texas, and an architecture & design studio in Denver, Colorado. Our Houston location provides proximity to major US transit corridors and international sea ports for seamless ocean freight shipment.
What production capacity does the Houston modular plant offer?
Our Houston plant houses 18 active production bays, specialized structural steel welding rigs, climate-controlled interior fit-out stations, and dedicated quality testing areas, enabling us to handle multi-unit commercial developments and large-scale modular rollouts.
Can overseas clients schedule factory inspections or live video tours?
Yes. We welcome international procurement managers, developers, and architectural partners to visit our Houston manufacturing facility in person. Alternatively, our engineering leadership provides live interactive video tours to review fabrication progress.
Why is factory-controlled modular fabrication superior to site-built construction?
Offsite manufacturing inside a controlled indoor plant eliminates weather downtime, maintains strict quality control oversight, optimizes material utilization, and reduces total project completion timelines by 30% to 50% compared to traditional on-site construction methods.
