18 SQM Detachable Container House Ships 18 Sets per 40HQ: The Logistics Case for Rental Investors
The Number That Decides Rental Profit: Units Per Container
For rental operators, the cheapest container house on a quotation sheet is rarely the cheapest project. Freight, handling and assembly labour usually exceed the unit price itself. Global House (Suzhou) Co., Ltd. builds its 18m² detachable container house around a single logistics figure: 18 sets per 40HQ container. That flat-pack density, combined with a three-hour assembly by four workers, resets the payback maths for rental, camp and site-office projects.
Product Specification
| Parameter | Specification |
|---|---|
| Footprint | 3 x 6 m (18m²) |
| Frame | 2.3–3.0mm galvanized steel, rust-proof |
| Design life | 8–10 years |
| Assembly | 4 workers, approximately 3 hours |
| Stacking | Up to 3 floors |
| Loading capacity | 18 sets per 40HQ |
| Flooring | Premium MGO board |
| Wind resistance | Level 10–11 |
The 18-Per-40HQ Calculation
Eighteen units in one container load changes three things at once. First, ocean freight per unit falls to a fraction of a rigid module of identical size. Second, port handling and inland trucking are consolidated into a single movement. Third, the receiving site needs no crane: panels are unloaded by forklift and assembled by hand.
| Cost Line | Effect of 18-Set Loading |
|---|---|
| Ocean freight | Divided across 18 units instead of 1–2 |
| Port and terminal handling | One container movement, one set of charges |
| Inland transport | Single truck per 18 units |
| On-site lifting plant | Not required — forklift and hand tools |
| Assembly labour | 4 workers x 3 hours per unit |
Assembled in One Shift
The detachable structure uses bolted panel joints, so a trained team completes an 18m² unit in a single working shift. No welding, no concrete pour and no wet trades. For rental operators this means a container can be cleared, assembled and handed to a tenant inside one week of arrival — and disassembled just as quickly when a lease ends.
Stack to Three Floors
The 2.3–3.0mm galvanized frame supports stacking up to three storeys, allowing dense site layouts on limited land. Available configurations include:
- Single-storey studio — 18m² rental unit with bathroom and kitchenette
- Two-floor portable shop — ground-floor retail with an upper balcony storey
- Bi-level commercial suite — external stairs and a viewing deck for roadside retail or lounges
- Duplex-ready guest house — multi-floor backyard accommodation with balcony
- Modular office block — open-plan 3 x 6m studios for remote teams and site administration
Built to Stay Rust-Free
Hot-dip galvanized framing resists corrosion in coastal and high-humidity environments, while MGO flooring resists moisture deformation better than timber or particle board. Panels are interchangeable, so a damaged wall section can be replaced without dismantling the unit — an important detail for rental fleets that are handled repeatedly.
Certified and Documented
Global House (Suzhou) Co., Ltd. supplies Triple ISO certification (9001, 14001, 45001), CE marking, UL-listed electrical options for US projects and asbestos-free declarations for Australian imports. Established in 2012, the company exports to more than 30 countries and serves over 200 clients from a facility producing 2,000 detachable units per month.
Request a Freight Build-Up
Send your destination port and target unit count, and Global House will return a full landing-cost build-up: ex-works price, freight per 18-set container, assembly labour estimate and a project payback model. Bulk orders above 100 units qualify for consolidated scheduling across the monthly 2,000-unit capacity.
