Ruifa Modular House
Engineered for high thermal resistance, structural safety, and immediate installation across Hai Phong's primary and industrial sectors.
Hai Phong, Northern Vietnam’s primary port city and dynamic economic hub, is experiencing unprecedented industrial expansion. As foreign direct investment (FDI) floods into economic zones like the DEEP C Industrial Zones, VSIP Hai Phong, and Trang Due, the city's urban footprint is changing rapidly. This sudden influx of industrial infrastructure and workforce migration creates an urgent need for structural development, especially in public utilities and educational facilities.
The growth of surrounding worker residential blocks and municipal districts demands rapid classroom installations that can keep pace with this demographic expansion. Traditional brick-and-mortar building methods require months or years of construction, causing dust pollution and high labor costs. Prefabricated school classroom buildings offer a quick-to-deploy, structural solution. These modular units can be manufactured off-site and assembled in a fraction of the time, making them an excellent choice for municipal developments, training centers inside free trade zones, and extensions of existing school structures in coastal communities.
Hai Phong's coastal location makes it vulnerable to tropical depressions, high humidity, and salt-mist corrosion. Standard modular structures designed for inland use will degrade quickly here. Our custom prefabricated classrooms feature anti-corrosion, double-coated hot-dip galvanized steel frames combined with high-density polyurethane (PU) or rockwool insulation. This ensures long-term performance and durability under local environmental conditions.
As a leading prefabricated house manufacturer in South-East China, we offer direct advantages in supply chain efficiency, advanced engineering, and coastal logistics. Our automated production facilities use robot-welding technology, automated roll-forming machines, and advanced powder-coating lines. This allows us to maintain consistent quality and high structural precision for every module we ship.
Shipping to Hai Phong is highly cost-effective due to our proximity to major maritime hubs like Ningbo, Shanghai, and Xiamen ports. Direct shipping lanes connect these ports to Lach Huyen deep-water port in Hai Phong, keeping shipping costs low and delivery times short. This close logistical connection allows us to deliver customized steel structures and sandwich panel components directly to your site quickly and efficiently.
Built to meet international building codes and stand up to challenging maritime environments.
Hot-dip galvanized steel frames are protected with a multi-layered, marine-grade powder coating (C3-C5 corrosivity rating) to prevent rust from salty air.
Engineered and certified to withstand winds up to 140 km/h and moderate seismic forces, making them ideal for coastal monsoon regions.
Constructed with premium Rockwool or Polyurethane (PU) sandwich panels, maintaining comfortable indoor temperatures and reducing acoustic noise from heavy rains.
Our modular solutions are designed to fit seamlessly into diverse layouts and environments. In corporate locations like VSIP Hai Phong and Nomura Industrial Zone, our multi-floor prefabricated school classrooms are used as modern, high-capacity corporate training facilities. In outlying and coastal areas, these structures are deployed as robust, insulated community schools that can handle seasonal flooding and high winds.
For global purchasing and procurement offices, we provide full support with detailed engineering drawings, structural calculations, material certifications, and environmental test reports. We work closely with our clients through every step—from initial planning and container optimization to on-site assembly guidance—to ensure compliance with local building standards in Northern Vietnam.
A look at our advanced manufacturing facilities and quality-control production lines in South-East China.
As one of the most professional prefabricated house manufacturers in south-east China, we provide customers with all kinds of integrated housing solutions. The company has a complete new modular housing R&D system, technology system, manufacturing system, and operation and maintenance system. Now it has a full set of production facilities such as small parts to guarantee maximum quality and structural control.


















The educational construction market is moving rapidly toward sustainable, energy-efficient designs. As governments implement ESG (Environmental, Social, and Governance) targets, prefabricated schools are changing how public projects are built. Off-site construction reduces materials waste by up to 30% compared to traditional on-site concrete pours, minimizing the overall carbon footprint.
These structures also allow for easy adaptation and clean disassembly at the end of their lifecycle. When school districts or industrial zones grow or change, modular classrooms can be taken down, moved, and set up in new configurations. This flexible, circular lifecycle offers long-term financial and environmental benefits, helping developers adapt to changing community and industrial needs.
