Off-Frame & On-Frame Modular Home

We offer two modular housing options based on steel structures – Off-Frame and On-Frame, to meet the architectural needs of different scenarios.

Off-Frame: Designed for permanent buildings. The modules are stabilized by self-supporting steel structures and are directly fixed to custom foundations, supporting multi-layer designs and complex functional partitions to meet the long-term use needs of residential and commercial spaces.

On-Frame: Designed for flexible deployment. The integrated chassis structure simplifies the transportation and installation process, suitable for temporary offices, emergency facilities or movable scenes, taking into account efficiency and functionality.

Balance of light weight and high strength
Factory prefabrication ensures process consistency
Environmentally friendly attributes throughout the life cycle

No need to compromise with the limitations of traditional buildings, your needs determine the form of the module.

Choosing our products will give you the following benefits:

Whether it is an Off-Frame modular house or an On-Frame modular house, we use cold-bent thin-walled steel, which reduces weight by 20% and increases weather resistance by 3 times. In addition, you will also enjoy:

Off-Frame modular house advantages

Real free design without chassis restrictions: Most modular buildings on the market rely on chassis or internal support structures, while our steel structure frame achieves a large-span space without columns (maximum 12-meter span without support) through distributed force design, and can freely plan complex layouts such as duplex and loft.

50-year damage resistance commitment: Adopting closed-loop steel structure node technology, the risk of rust caused by traditional bolt splicing is eliminated, and the main structure is maintenance-free for 50 years.

Hidden cost reduction: No additional reinforcement is required to adapt to harsh environments such as earthquake zones and strong wind zones, eliminating the foundation reinforcement costs of traditional solutions. Matt coatings can be customized for the exposed parts of the steel structure, eliminating the finishing costs of traditional buildings.

Climate-free design: The module interface adopts a sealed double-layer insulation layer, which is suitable for extremely cold, high humidity or desert environments, and eliminates the condensation and thermal bridge effects of traditional spliced houses.

Quiet performance: The cavity structure is embedded with damping materials to isolate wind, rain and external noise, which is better than the sound insulation performance of conventional modular buildings.

Advantages of On-Frame modular houses

Rapid deployment capability: Integrated chassis and pre-installed water and electricity interfaces, the function is enabled within 24 hours after arriving at the site.

Lossless mobile technology: Supports multiple disassembly and relocation without structural loss, while the performance of similar products decreases by about 30% after moving

Scenario adaptive expansion: A single module can be used independently, or it can be infinitely spliced horizontally through the slide rail system, meeting the seamless upgrade from a single workstation to a large camp.

Anti-deformation chassis: The chassis beam adopts a staggered stress dispersion design, which can maintain horizontal stability even if it is parked on uneven ground for a long time.

Pre-installed system integration: Water and electricity pipelines are pre-buried in an integrated manner with the chassis, and on-site docking only requires plug-in operation, without the intervention of professional technicians.

Minimum storage space: The module can be completely folded into a flat state, and the transportation and storage space is only 1/5 of the unfolded state, reducing customer inventory costs.

Off-Frame Modular Home Recommended: Long-term residence, stability and comfort

If you want a stable, solid home, the Off-Frame Modular Home is the ideal choice. It is installed on a fixed foundation and provides the same security, comfort and long-term value as a traditional home. Ideal for:

Permanent residence: Whether in the city, suburbs or rural areas, Off-Frame homes provide a stable living experience and meet local building codes.
Family expansion: Need extra space? It can be used to build a separate in-law house, guest room or private office.
Investment property: It is suitable as a rental property because of its low maintenance cost and long-term durability, providing a reliable return on investment.
High-end custom home: Supports a variety of architectural styles and smart home configurations to make your home more personalized.

On-Frame Modular Home Recommended: Flexible and convenient, suitable for short-term or mobile residence

If your needs are more flexible, or you need a mobile home, the On-Frame Modular Home is more suitable for you. With a steel chassis, it can be easily transported and is suitable for:

Holiday home / country cabin: as a weekend getaway residence, it can be easily placed in the mountains, lakes or seaside without complicated construction.
Temporary residence: suitable for construction sites, remote workstations, or as a short-term living solution.
Mobile home / easy migration: suitable for users who need to change their residence regularly, such as nomadic lifestyle or travellers.
Rental business / Airbnb short-term rental: can be used as a flexible rental property to attract tenants seeking a unique accommodation experience.

Whether your needs are a stable long-term residence or a convenient mobile home, our modular homes can provide the best solution to make your life more efficient and comfortable!
