Frequently Asked Questions on Factory-Built Steel-Framed Homes
Direct, expert answers to the most common technical, logistical, and structural questions posed by international buyers, engineers, and developers.
How fast can a BoxHouse steel-framed home be deployed on site?
Our official, documented deployment record for the 380 sq ft BoxHouse Duplex is 1 hour and 26 minutes from crane positioning to fully unfolded exterior frame lock. Once the structure is unfolded and mechanical locks are engaged, internal utility connections (electrical main hookup, PEX water line joinery, and waste line drops) typically require 2 to 4 additional hours. Provided that ground footings or helical anchors are prepared prior to delivery, a unit can achieve full move-in readiness on the exact day of delivery.
How many steel-framed homes fit inside a single standard ocean container?
Thanks to our patented flat-pack folding chassis design, up to two complete, fully finished BoxHouse units collapse into the footprint of a single 40ft High Cube (HQ) ocean shipping container. This high volumetric packing density cuts ocean, rail, and over-the-road freight costs by up to 75% per housing unit compared to fully volumetric modular boxes. It allows procurement officers to ship entire 50-unit housing villages on standard container vessels without requiring specialized breakbulk freight handling.
What specific wind load and seismic ratings do these steel homes achieve?
BoxHouse homes are built around a cold-formed Q355B structural steel framework engineered to withstand continuous wind uplift and lateral pressure forces of up to 200 mph (89 m/s), qualifying them for Category 5 hurricane zones, coastal shorelines, and typhoon-prone island environments. Additionally, the inherent ductility of cold-formed structural steel framing allows the building envelope to absorb intense lateral accelerations without structural failure, meeting International Building Code (IBC) Seismic Design Category D/E (Seismic Zone 4) standards.
Is a permanent concrete slab foundation mandatory for installation?
No. While BoxHouse units can be anchored onto traditional poured concrete slabs, stem walls, or concrete piers for permanent residential development, they are equally certified for rapid installation on engineered helical ground screws (earth screws). Helical anchors eliminate the need for concrete mixing, cure delays, and ground excavation, enabling rapid zero-land-disturbance setups. This foundation flexibility makes the units ideal for temporary workforce camps, environmental reserves, or land leases where site restoration is required post-occupancy.
What interior finishes, appliances, and fixtures are included from the factory?
BoxHouse homes leave the manufacturing line 90% to 95% complete. Standard procurement packages include: fully insulated exterior wall panels, dual-pane low-E tempered glass windows, insulated exterior security doors, pre-wired NEMA/CE electrical distribution panels and LED lighting, pre-plumbed PEX water lines and PVC drainage, a fully equipped bathroom (shower enclosure, ceramic toilet, vanity, fixtures), and kitchen/kitchenette cabinetry with stone or composite counter surfaces. Custom commercial specifications can also integrate pre-installed HVAC mini-split systems, washer/dryer hookups, and furniture packages.
How does cold-formed steel framing perform in terms of thermal efficiency and moisture barrier control?
Steel has high thermal conductivity, which is why BoxHouse incorporates continuous exterior thermal breaks and high-density polyisocyanurate (PIR) or stone wool insulation cores within the wall cassette assembly. This system eliminates thermal bridging and prevents condensation inside wall cavities. The thermal insulation performance delivers wall values ranging from R-19 to R-38 depending on climate zone configuration, while integrated vapor-permeable weather barriers protect against moisture ingress and mold growth.
What is the structural design lifespan and anti-corrosion protection of the steel frame?
The primary structural steel chassis is manufactured from heavy-gauge steel treated with hot-dip galvanization (minimum Z275 / G90 zinc coating density) or zinc-aluminum-magnesium alloy protection. This prevents rust formation even in marine or humid tropical atmospheres (C4/C5 corrosion classification). The theoretical structural lifespan of the frame exceeds 50 years under standard operating conditions, requiring minimal structural maintenance compared to timber framing which degrades from rot, termites, and moisture warping.
How are electrical, plumbing, and HVAC systems connected for international building code compliance?
All internal utility systems are pre-installed within the factory walls and floors according to target country standards (such as US National Electrical Code NEC / IBC, European CE standards, or Australian AS/NZS codes). Standard utility connection points are centralized at dedicated external quick-connect access panels on the rear exterior wall. On site, local licensed electricians and plumbers simply connect the municipal or off-grid power feed, water supply inlet, and sewer outflow drop to these unified junction panels.
What is the typical production lead time and ocean transport schedule for bulk B2B orders?
Factory production lead time depends on order volume. Standard batch orders (10 to 50 units) are typically manufactured within 20 to 30 calendar days at our automated facility. Ocean shipping schedules vary by destination port: approximately 15–20 days to West Coast North America, 25–35 days to European ports, and 12–18 days across Australia and the Pacific Islands. Expedited air-freight transport or prioritized production slots are available for urgent disaster relief contracts.
Can BoxHouse steel-framed homes be customized for OEM / ODM volume projects?
Yes. For real estate developers, mining enterprises, and public agencies ordering in volume (minimum 10 units), our in-house structural engineering and architectural team provides comprehensive OEM/ODM customization. This includes custom floor plan reconfigurations, exterior cladding choices (composite wood, standing seam metal, fiber cement panels), modified interior floor finishes, custom window placements, and specialized MEP layouts designed to satisfy localized municipal zoning codes.
