Why International Buyers Trust PackPrefab Manufacturing
27+ Years Factory Experience
Since 1998, our 500,000 sq ft manufacturing hub has designed and built modular steel structures. We do not source from third parties; every joint, wall panel, and wiring harness is controlled in-house under ISO quality standards.
Optimized Freight Economics
By folding down to a compact transport width, two (2) complete Expandable Deluxe Max homes can be stacked and secured into one 40-foot High-Cube ocean shipping container, dramatically lowering international sea freight costs per unit.
Rapid Turnkey Deployment
Modules arrive fully finished with factory-installed wiring, plumbing schematics, and wet rooms. A crew of 4 workers using standard hoisting machinery can deploy, level, seal, and prepare a unit for occupancy in under 8 hours.
Frequently Asked Procurement Questions
Each unit folds into a self-contained transport cassette measuring 19’7” x 7’7” x 8’4”. Two complete units fit inside a standard 40ft High Cube container for ocean transit, or individual units can be flatbed-trucked straight to your job site.
The integrated steel chassis load is supported by corner and intermediate footings. Concrete pad footings, strip footings, or ground screw piles are ideal. A full poured concrete slab is generally not required, which shortens ground preparation time and cuts civil work budgets.
Yes. Electrical conduits, sockets, breaker panels, and lighting fixtures are integrated into the wall cassettes during factory assembly. The bathroom and kitchen modules include pre-plumbed drainage and water supply connections ready to connect to site utilities.
The Deluxe Max is engineered to withstand wind loads up to 156 mph (Category 5 hurricane speeds), roof snow loads of 25 psf, and Category E/F seismic activity. Full structural calculations and engineering documentation are provided for permit submission.
