Brand: Prefabex

Industrialized Housing Solutions for International B2B Projects

Prefabex specializes in engineering and manufacturing modular residential systems designed for rapid deployment, high thermal efficiency, and long-term structural integrity. We work exclusively with main contractors, real estate developers, government ministries, housing authorities, and international non-governmental organizations delivering multi-unit housing developments worldwide.

Our off-site modular construction methodologies transfer up to 80% of building work from the job site into a climate-controlled factory environment. This approach reduces overall construction schedules by up to 50%, controls material waste, guarantees strict quality compliance, and minimizes site labor demands in remote or labor-constrained project locations.

Key Advantages for Overseas Procurement & Developers

By pairing advanced off-site manufacturing technology with comprehensive international logistics, Prefabex delivers reliable B2B performance for complex multi-unit housing contracts.

Accelerated Project Timeline

Parallel manufacturing during site foundation work allows rapid completion, enabling project developers to realize earlier rental or sales revenues and reduce overall financing costs.

Factory Precision Quality

Buildings are constructed under automated, climate-controlled factory environments, eliminating weather delays and guaranteeing uniform structural dimensions and tolerances across hundreds of units.

Optimized Export Logistics

Components are specially flat-packed or module-designed for standard sea container shipping (40ft HQ), minimizing global transport tariffs and freight expenses for overseas projects.

Customizable Engineering

In-house architectural, structural, and MEP engineering teams adapt structural loads, wall insulation values, and interior finishes to match destination climate conditions and regional building regulations.

Energy-Efficient Envelope

High-performance thermal insulation layers and airtight building envelopes significantly reduce operational HVAC energy consumption over the lifetime of the residential community.

Complete Turnkey Execution

From initial shop drawing submittals to manufacturing, international logistics coordination, and site assembly supervision, Prefabex provides a single point of accountability.

Frequently Asked Questions

Key information for project procurement managers, civil engineering consultants, and commercial real estate developers.

What is the typical lead time for a large-scale modular housing project?

Lead times depend on total building square meterage and engineering customization. Engineering approvals usually take 2 to 4 weeks, while factory production averages 500 to 1,000 m² of residential space per week under standard operating capacity.

How are Prefabex modular houses shipped internationally?

Modular building components are engineered for global export using flat-pack bundling or volumetric module framing optimized to fit standard 40ft High Cube sea shipping containers, reducing transport costs and protecting finishes in transit.

Can Prefabex modular homes comply with local seismic and wind load codes?

Yes. Our engineering department performs site-specific structural calculations (including finite element analysis) for wind loads up to 180 km/h and seismic zones up to Zone 4 / Category D, ensuring compliance with local municipal building regulations.

Does Prefabex supply on-site installation services or supervision?

Prefabex provides detailed assembly drawings, step-by-step installation manuals, and can dispatch experienced site engineers or complete erection teams to supervise and complete the on-site assembly of your project globally.
