Modern construction projects demand efficiency, durability, and cost-effectiveness. The Fold Out Container from WECHEER Holding Group delivers precisely that—an industrial-grade folding module engineered for heavy-duty applications. With more than 300,000 modular container sets produced annually and more than 40 years of manufacturing experience, WECHEER creates units that adhere to strict international requirements. The export-optimized version (W2500 × L5900 × H2500mm) permits 8 units per 40HQ container, while our ordinary domestic model measures W2990 × L6055 × H2896mm. These units, which are constructed on hot-dip galvanized steel frames with rock wool or PU fire-rated insulated panels, offer over ten years of durability for ongoing industrial use.
Materials for your project should be able to endure challenging conditions. The heavy-gauge galvanized steel frames in our product have been hot-dip galvanized to provide exceptional corrosion protection. The insulated sandwich panels have 75mm cores; for typical applications, use EPS; for high-risk locations, use Class A fire-rated rock wool; or for improved thermal performance, use premium PU.
A three-layer fiber cement substrate supports 3mm anti-slip PVC flooring, and the waterproof roof system consists of insulated panels with a unique coating. In a variety of climates, this engineering method provides weatherproof protection for site offices, workshops, equipment rooms, security checkpoints, and control rooms.
Project budgets are greatly impacted by freight costs. This problem is resolved by our large-frame export model, which fits eight completely functional units into a single 40HQ container. When compared to traditional modular buildings, this industry-leading packing density significantly lowers your per-unit shipping costs.
Compact transportation is made possible by the fold-out mechanism, which retains full operation when deployed. You are making the most of each cubic meter of container space rather than paying for air transportation.
On active building sites, time is money. In less than two hours, our unique one-pull construction method turns a flat-packed unit into a room that is ready for use. Without large machinery or cranes, installation can be finished by just two to four persons.
An 8-circuit breaker panel, RCCB protection, outlets, switches, and LED strip lighting are examples of pre-integrated electrical systems. Steel security doors and UPVC casement windows (1130 x 1100 mm) are pre-installed, saving time on on-site fitting.
These modules deconstruct and reassemble repeatedly without experiencing structural deterioration, in contrast to permanent buildings. In order to maximize asset usage, your investment follows you from project to project. For successive infrastructure projects, companies that work with China Railway, China State Construction, and China Communications Construction depend on this reusability.
Through numerous deployment cycles, the galvanized frame and modular panel system preserves structural integrity and offers a remarkable return on investment.

Infrastructure and Construction Projects
Our Fold Out Container is used by major contractors for equipment storage, conference rooms, worker dorms, and temporary site offices. The units endure harsh conditions during the construction of high-speed railroads, motorway projects, and water conservation initiatives.
Sectors of Industry and Energy
In isolated areas, mining facilities and oilfield camps need dependable shelter. With optional 3-phase electrical systems to meet industrial power needs, our containers provide instant safety for people and equipment.
Uses in Commerce and Security
These units are used by retailers as exhibition spaces and pop-up stores. They are used by security teams for checkpoint stations and guard booths. Applications that deal with customers benefit from the sturdy build and polished look.
Global Export Markets
Products from WECHEER support initiatives in more than 100 nations. When local building resources are few, contractors in Mexico, Southeast Asia, the Middle East, and Africa use our containers for turnkey lodging options.

Each project has specific needs. From single-room dorm arrangements to divided accommodations with bedroom and bathroom parts, we provide completely configurable interior plans. Wall panel colors, door swing direction, and window location all adjust to your preferences.
Fitted furniture, such as beds, desks, lockers, and bathroom fittings, are included in turnkey packages. Together, you and our design team optimize layouts to meet your unique operational requirements.

Every unit is shipped in normal shipping containers, folded and flat-packed. Our six smart manufacturing facilities in China guarantee prompt delivery and effective production. We handle logistics from the plant to your project site with more than thirty service locations around the country.

Q: What is the difference between the standard and export models?
A: The standard domestic model (W2990 × L6055 × H2896mm) provides larger interior space for the Chinese market. The export model (W2500 × L5900 × H2500mm) maximizes container loading efficiency for international shipping, reducing freight cost per unit. Both models maintain identical structural quality and material specifications.
Q: How does the folding mechanism work?
A: Workers pull pre-hinged wall panels outward and lock them into position—a process requiring no special tools or cranes. Roof panels install last to complete weatherproofing. Full setup takes 1-2 hours with 2-4 workers.
Q: What fire safety rating does the unit carry?
A: We offer Class A (non-combustible) using rock wool panels, and Class B1 (flame retardant) using EPS-core panels. Both comply with Chinese national standards (GB) and include test certificates for international requirements.
Q: Can interior configurations be customized?
A: Yes. Layouts are fully customizable, including furniture packages, custom window placement, door configurations, and wall panel colors tailored to your project requirements.
