What is SINO-HUNAN Steel Modular Housing?
Steel-frame modular homes are permanent prefabricated structures that are fully manufactured in a factory and rapidly assembled on-site. Featuring a heavy-duty steel frame, these homes come equipped with insulated walls, complete plumbing and electrical systems, and finished interiors. They require no complex on-site construction, offer fast installation and high safety standards, and can be built in multiple stories, making them a viable alternative to traditional concrete homes and temporary container housing.

Number of Stories & Load Parameters
Multi-Story Vertical Stacking
Main structure and high-tolerance joints sustain vertical load vectors perfectly. GS Armor designs support "vertical nesting up to 6 stories", recommended at 3 to 4 stories (our Sulawesi mining dorms operate as 3-story structures).
Minimalist Base Foundations
Weighing 80% less than traditional brick configurations, our buildings "only require basic strip beams or concrete columns". Avoids massive excavation or deep pile drilling in sandy zones.
Custom Wide-Span Options
Beyond classic container dimensions, we offer wide-span designs up to "3.2m × 12m" of column-free layout spaces. Ideal for meeting rooms, public cafes, and commercial hubs.

Export & Logistics Technical FAQs
If you have questions regarding factory timelines, customs clearances, or structural finishes, find professional answers to our clients' most frequent concerns below.
Is this a temporary or permanent building?
It is a permanent steel structure building, not a temporary container house. It is eligible for local overseas building permits and can be used legally and for extended periods.
What is the lifespan of the modular house?
The main structure is made of hot-dip galvanized steel, providing excellent rust and corrosion resistance. The standard design lifespan is up to 50 years, meeting the needs of long-term overseas construction.
What is the maximum number of stories that can be built on the modular house?
The product can be stacked up to 6 stories. In overseas projects, 1-4 stories are commonly used for employee dormitories, apartments, and office buildings, ensuring structural stability and safety.
Can the house withstand various extreme weather conditions overseas?
Yes. The house is designed to withstand 12-level typhoons, 7-8 level earthquakes, and is Class A fireproof, perfectly adapting to harsh overseas environments such as coastal salt corrosion, desert high temperatures, rainforest rain, and high-altitude cold conditions.
Does the house come equipped with complete interior decoration and a complete water and electricity system?
The entire house is prefabricated and fully furnished in the factory, equipped with standard water and electricity lines, doors and windows, lighting, and basic kitchen and bathroom facilities. After on-site hoisting and assembly, it is ready for immediate occupancy.
Is overseas shipping and on-site installation convenient?
The modules are of standard size and compatible with international 20GP/40GP shipping containers, facilitating cross-border transportation. No complex wet work is required on-site; only hoisting and assembly are needed, significantly reducing overseas construction difficulty and labor costs.
Can the house be disassembled, relocated, and reused?
Yes. The modular assembly structure can be freely disassembled, relocated, reassembled, and expanded. The layout can be adjusted according to project needs, with minimal material loss, allowing for reuse and offering excellent cost-effectiveness.
What international certifications does the product have?
The product is manufactured in strict accordance with CE and ISO international standards, possesses formal international certifications, and meets the construction and import access requirements of most countries worldwide.
Which overseas projects are modular houses primarily suitable for?
Widely applicable to various permanent building projects such as employee dormitories in overseas industrial parks, construction site office buildings, cultural tourism resorts, overseas school buildings, mining camps, and government-subsidized housing.
Compared with traditional buildings, what are the advantages of this product in terms of construction period?
The product has a factory prefabrication rate of over 90%, eliminating the limitations of traditional on-site construction. The overall construction period is shortened by 90% compared to concrete buildings, and small to medium-sized projects can be completed and delivered in 1-3 months.
