About ROXBOX Containers
Premier Steel Frame Modular & Custom Shipping Container Architecture
Industry-Leading Modular Architecture
Engineered Offsite Construction & Manufacturing
ROXBOX Containers is an employee-owned modular architecture and offsite manufacturing firm specializing in cold-formed steel frame modular buildings and modified ISO shipping container structures. Headquartered in Denver, Colorado, with a 40,000 sq. ft. advanced manufacturing plant in Houston, Texas, we provide global procurement teams, developers, and commercial brands with turnkey modular assets.
With over 30 years of combined team experience in structural engineering, architectural design, and industrial steel fabrication, ROXBOX controls every phase of production offsite under one roof. Our streamlined design-build workflow accelerates project completion timelines by 30% to 50% compared to traditional on-site construction.
Our Core Principles
The ROXBOX Promise to Global Buyers
We combine structural precision, factory quality control, and international building code compliance to de-risk project schedules for overseas developers and enterprise clients.
Transparent Communication
Real-time BIM scheduling, continuous production reporting, and dedicated project managers for seamless multi-site rollouts.
Guaranteed Delivery Timelines
Offsite fabrication occurs in parallel with site foundation prep, completely mitigating weather delays and labor shortages.
Industrial Quality Assurance
Climate-controlled factory precision with certified structural welding, third-party code inspections, and rigorous pressure testing.
Manufacturing Expertise
Two Modular Structural Systems Built for High Performance
Whether your commercial program requires custom multi-story floor plans or high-durability rapid container modules, ROXBOX delivers engineered solutions built to standard.
Steel Frame Modular Buildings
Built using cold-formed steel (CFS) framing and engineered chassis. Ideal for multi-story hospitality resorts, quick service restaurant (QSR) drive-thrus, commercial offices, and off-grid remote developments requiring wide structural spans and customized architectural envelope treatments.
Modified Shipping Container Structures
Engineered using heavy-gauge ISO single-trip corten steel shipping containers. Designed for rapid-deployment retail pop-ups, concession bars, industrial field enclosures, mobile medical facilities, and experiential brand activations built to endure harsh transport and weather environments.
