The apple cabin — a rounded, pod-shaped prefabricated structure originally popularized in China's glamping and tiny-house market — has grown into a global modular building category. It is now specified for eco-resorts, backyard ADUs (accessory dwelling units), vineyard stays, mobile offices, and even emergency housing. Because the category has expanded so quickly, quality, structural engineering, and after-sales support vary widely from one factory to the next.
What Is an Apple Cabin, Technically?
An apple cabin is a factory-built modular unit constructed on a lightweight, hot-dip galvanized steel frame rather than a poured foundation. Panels are prefabricated off-site, shipped flat or semi-assembled, and bolted together on location — which is what allows most units to be installed within days rather than months. Unlike a converted shipping container, an apple cabin is engineered from the start as a living pod, which typically gives it better insulation continuity and a distinctive curved roofline.
Because "apple cabin" is a product category rather than a single fixed spec, the table below summarizes the technical range you should expect to see across reputable manufacturers, along with a representative example drawn from a published factory data sheet.
| Component | Typical Industry Range | Representative Spec (Cymdin C06 model) |
|---|---|---|
| Frame structure | Hot-dip galvanized light steel, bolted/welded modular frame | Hot-dip galvanized seismic steel frame |
| Exterior cladding | 1.5–3 mm aluminum veneer or composite panel, fluorocarbon-coated | 2.5 mm aluminum veneer, fluorocarbon baking-paint finish |
| Glazing | Double or triple tempered Low-E glass curtain wall | Double-layer tempered Low-E glass (6+12+6 mm) |
| Wind resistance | Typhoon-rated, manufacturer-tested | Rated for Class 12 typhoon-equivalent loads |
| Seismic rating | Grade 7–8 (region-dependent) | Above magnitude 8 |
| Service life | 20–70 years, depending on materials and maintenance | 20+ years rated life, up to 50-year design life |
| Power options | Grid, solar, or hybrid solar/wind self-sufficiency | Solar power supply system available |
| Lead time | 13–25 days after order confirmation, standard configurations | Varies by customization level |

How We Evaluated These Manufacturers
To keep this list useful rather than promotional, each company was assessed against five criteria commonly used in industrial procurement: years of manufacturing experience, factory ownership versus trading-company status, published technical specifications, export track record, and range of product customization. This mirrors the approach recommended by international sourcing platforms for verifying prefab and modular suppliers before placing an order.
Top 10 Apple Cabin & Modular Cabin Manufacturers
1. Shanghai Cymdin Industrial Co., Ltd.
Headquarters: Shanghai, China | Established: 2008 | Website: cymdin.com

2. Qingdao Storage Metal Technology Co., Ltd.
Headquarters: Shandong Province, China
Based in Shandong's concentrated modular-manufacturing cluster, this company focuses specifically on apple cabin houses, expandable container houses, and customized modular building solutions for export markets. Its position in a region with established steel and composite-material supply chains supports competitive lead times on standardized product lines.
3. Sun Rises Group Limited
Headquarters: China
Sun Rises Group manufactures apple cabin houses using SG550-grade steel with a stated service life exceeding 70 years for select product lines, and offers wind-resistance ratings up to Level 11 and seismic ratings up to Level 8 on its standard container-based models. The company's catalogue also covers double-wing expandable container houses, positioning it as a supplier for buyers who want both apple-cabin-style pods and traditional expandable container housing from one factory.
4. Shandong Mars Cabin Technology Co., Ltd.
Headquarters: Shandong Province, China
This manufacturer is frequently cited by sourcing platforms for fast turnaround and a low minimum order quantity (as small as 15 square meters), making it a fit for buyers testing a single unit or a small pilot deployment before committing to a bulk order.
5. Guangzhou Zhonglian Steel Structure Co., Ltd.
Headquarters: Guangdong Province, China
Operating out of Guangdong's advanced manufacturing corridor, this company is noted for customization depth and multi-use design work spanning hospitality, office, and event-space applications — a useful option for commercial buyers who need non-standard floor plans rather than a catalogue unit.
6. Qingdao BD Cloud Technology Co., Ltd.
Headquarters: Qingdao, Shandong Province, China
This supplier is regularly highlighted in tourism and hospitality sourcing comparisons for consistent on-time delivery performance and strong reorder rates from repeat B2B buyers, which is a useful signal of reliability for larger resort or campsite rollouts.
7. Shanghai Conrayn Industrial Co., Ltd. (CONRAYN)
Headquarters: Jinshan, Shanghai, China | Product line launched: 2019
Conrayn's Mobile Apple Cabin uses a hot-dip galvanized steel structure combined with carbon-fiber composite wall panels and a thermally broken (bridge-breaking) aluminum double-glazed curtain wall, with SPC flooring inside for moisture resistance. Its one-piece wall molding process is a distinct manufacturing approach compared with panel-and-frame assembly used elsewhere in the category. The company states its units are currently sold in more than 20 countries.
8. Liansheng International
Headquarters: China
Liansheng markets itself around fast assembly aided by 3D modeling in the design and production process, targeting premium and luxury-tier apple cabin capsule houses rather than budget-tier units.
9. Shandong Zhongda Construction Engineering Co., Ltd.

A Buyer's Checklist Before You Order
- Confirm the supplier is an actual factory, not a trading company reselling another manufacturer's product — ask for factory photos or a virtual factory tour.
- Request wind-load and seismic ratings in writing, not just marketing copy, and check they match your installation region's building code.
- Ask for the exact glazing spec (glass thickness and air-gap) — this is the single biggest driver of thermal comfort in a steel-and-glass pod.
- Clarify what "service life" means: rated lifespan under normal use versus maximum design life under ideal maintenance are two different numbers.
- Get a written lead time tied to your specific configuration, since standard units ship faster than heavily customized layouts.
- Check export documentation history — CE, ISO, or regional certification relevant to your destination country.
The apple cabin market has matured from a niche glamping product into a genuine modular-construction category with real engineering differentiation between suppliers. Rather than choosing on price alone, compare frame material, glazing spec, certified wind/seismic ratings, and export track record side by side — the checklist and comparison table above are meant to make that process faster. For buyers who want a single manufacturer covering the full range of apple cabins, space capsule houses, and modular buildings with openly published technical data, Cymdin is a reasonable first stop for a quotation, alongside the other manufacturers profiled here.
