Wanzhi Group is not merely a metal materials supplier; we are a cross-industry solutions provider, offering solutions for high-end home appliance manufacturing, Prefab Steel Homes, and more. In the Prefab Steel Homes sector, we integrate the entire chain of capabilities, from galvanized steel raw material production and component processing to modular assembly and logistics delivery, providing one-stop services from design to implementation for industries such as manufacturing, agriculture, and tourism.
Prefab Steel Homes – Raw Material Construction
Wanzhi Group’s Prefab Steel Homes raw material construction solution uses its own Z30-Z350 galvanized steel as the core, combined with customized corrugated metal sheets and accessories, forming a “high-strength + long-lasting corrosion-resistant” basic structure, suitable for scenarios with clear requirements for stability and durability.
Material
- Materials: Main Structure: High-strength galvanized steel keel, C-shaped steel purlins, Z-shaped steel supports, square tube columns. The base material is selected from DC51D+Z (standard structure), DC56D+Z (high-strength structure), and Q235B+Z, with a zinc coating coverage of ≥180-275g/㎡, ensuring excellent corrosion resistance and structural durability, with a service life of over 50 years.
- Enclosure System: High-quality PPGI PPGL corrugated sheets (profiled steel sheets) are used for wall panels and roof panels. Different waveforms (corrugated, sine, trapezoidal, etc.), thicknesses (0.3-0.8mm), and surface coatings (such as SMP, HDP, PVDF, PU) are available to meet multi-level needs from basic protection to aesthetic decoration.
- Integrated Accessories: A complete set of high-performance connectors (bolts, brackets, sealing strips), insulation materials (glass wool/rock wool), door and window systems, and roof waterproofing components ensure tight connections and long-term leak-proof performance.
Features
- Material Traceability and Control:All galvanized steel raw materials, corrugated sheets, and components are produced in our own factory, ensuring full control over everything from base material purity to coating thickness.
- Ultimate Economy and Efficiency:Highly standardized materials allow for quick processing and easy installation, increasing construction efficiency by 4 times compared to traditional brick-and-mortar buildings.
- Robust and Reliable: The steel structure is lightweight yet high-strength, offering excellent earthquake and wind resistance.
- Flexible and Scalable:The structural system is easy to connect and extend, facilitating project expansion or functional modifications.
- Low Lifetime Cost:Z30-Z350 galvanized steel + color-coated corrugated sheets provide long-lasting corrosion protection.
Applications
- Industrial plants
- Large-span storage centers
- Greenhouses
- Livestock farms, grain storage warehouses
- Temporary buildings
Prefab Steel Homes – Modular Housing
Based on a basic steel structure system, we offer a highly integrated and intelligent modular living solution – prefabricated container homes – perfectly blending industrial-grade robustness with residential-grade comfort. It simultaneously meets the needs for rapid deployment, flexible space, and convenient relocation.
Housing Types
- Extendable Prefab Homes:With a galvanized steel frame core, these homes maintain standard container dimensions during transport. On-site, the two side walls are extended outwards as a whole using hydraulic or mechanical devices. Area ranges from 18-76㎡.
- Prefab Folding Container Homes:These homes can be vertically folded, compressing their height to 1/3 of their standard size during transport. Upon arrival, they are quickly unfolded, offering ultimate portability.
- Push-Pull Apple-Style Homes:These homes utilize segmented pushing and pulling mechanisms to create staggered, three-dimensional spaces, flexibly creating balconies, terraces, and other transitional areas with a novel design.
Modular System Advantages
- Mobility:Prefabricated Steel Houses support repeated disassembly and assembly, allowing them to be moved with the project. Rapid Deployment: Over 90% of the decoration and equipment installation is completed in the factory; once on-site setup is complete and utilities (water, electricity, internet) are connected, residents can move in immediately.
- Customization Freedom: Deep customization is supported for exterior materials (wood grain panels, metal carved panels, etc.), interior layout, and smart home systems.
- Economic Benefits: Lower cost compared to traditional concrete/wooden houses.
Applications
- Permanent or semi-permanent residences
- outdoor workstations; vacation villas and guesthouses
- temporary construction site dormitories
- temporary reception centers
- emergency command posts
- temporary industrial and mining camps
- urban micro-space utilization (e.g., rooftop additions)
- cultural and creative commercial spaces
- exhibition centers.
Prefab Steel Homes – Factory
Wanzhi Group‘s core advantage in Prefab Steel Homes lies in shifting home construction from the traditional “construction site” to a controlled “factory,” achieving “manufacturing” of homes through digitalized assembly lines. This shortens project cycles while reducing costs and improving construction convenience. The Wanzhi prefab steel homes factory integrates three core workshops: raw material production, component processing, and modular assembly, providing the core strength for a one-stop solution.
Full-Chain Customization and Service
- Material Customization: We adjust galvanized steel specifications, wall/roof/floor thickness, and style according to specific scenarios.
- Interior Finishing: Interior layout and finishing modules are customized according to application needs, including flooring, walls, plumbing and electrical systems, furniture, functional areas, etc.
- Fast Delivery: 90% of the modular home construction is completed in the Wanzhi Group factory; standard modules can be produced within 15 days.
Capacity and Production Lines
- Raw Material Workshop: Two Z30-Z350 galvanized steel production lines and several corrugated sheet roll forming production lines ensure self-sufficiency in core materials.
- Component Processing Workshop:Equipped with automated equipment for laser cutting and cold bending, capable of processing galvanized steel structural components of various shapes.
- Modular Assembly Workshop:Modular housing assembly line, equipped with a hydraulic assembly platform and interior pre-assembly workstations, capable of simultaneously producing double-wing extendable, folding, and push-pull modules.
Factory Quality Control System
- Raw Material Inspection:Galvanized steel coating thickness testing; adhesion testing (≥4B grade) to ensure compliance with international standards such as ISO/EN/ASTM/JIS/GB.
- Component Inspection:Purlins and columns undergo load testing; weld points undergo flaw detection.
- Finished Product Inspection:Modular houses undergo waterproofing testing and extendable/folding function testing before leaving the factory.
Factory One-Stop Service Process
- Demand Matching:Customized solutions are developed based on customer needs (purpose, size, environment, budget).
- Design and Production:OEM/ODM for metal materials and prefabricated houses, with a delivery time of 5-45 working days.
- Installation Guidance:Detailed installation manuals (including video tutorials) and online guidance are provided.
