What container sizes does CIMIC supply?

Our reefer, dry and insulated lines are available in 10ft, 20ft, 20ft high cube, 40ft and 40ft high cube. Half-height, side open door, roll-up door, open-top, offshore and modular containers are built to project specifications.

Which refrigeration unit brands are available on your reefer containers?

We supply reefer containers fitted with Thermo King, Daikin and Carrier refrigeration units across our new and used ranges. Share your cargo set-point and on-site power supply so our engineers can recommend the right unit.

What certifications do your containers and factory hold?

CIMIC holds an ISO quality management certificate and a BV (Bureau Veritas) shipping certificate. Our offshore dry cargo containers are manufactured in compliance with DNV certification. ISO containers used in international transport should carry a valid CSC safety approval plate, and we confirm the documentation of each unit before shipment.

What is the difference between a reefer container and an insulated container?

A reefer container has an integrated refrigeration unit that actively cools or heats cargo to a set temperature and needs a power supply. An insulated container uses thickened foam walls to slow temperature change passively, with no power required, which suits shorter routes and temperature-sensitive cargo that does not need active freezing.

Are your used containers inspected before sale?

Our second-hand containers are units retired from shipping line fleets and are stored at various ports in China. We share photos and condition details of the specific unit you are buying so you can verify structure, doors, floor and, for reefers, the refrigeration unit before shipment.

Do you accept OEM, ODM and custom container orders?

Yes. We build tailor-made OEM and ODM containers and provide one-to-one engineering support. Stock and used units can usually be ordered in small quantities, while the minimum order quantity for custom builds depends on the specification.

Product Description

Product Introduction

The dual-wing expandable container house is a type of prefabricated, modular integrated housing featuring "wing" sections on both sides that can fold inward. During transport, the wings retract to match the width of a standard shipping container, allowing for direct export via 40HQ containers. Upon arrival at the site, the wings are unfolded and locked in place, expanding the usable area by approximately two to three times. Requiring no on-site wet construction and taking just over ten minutes to install, it is a highly popular mobile housing product in the export market.

General Use Scenarios

Scenic Area Campsites & Guesthouses / Luxury Glamping Units

Many campsite sites are designated for temporary use or are leased land, prohibiting permanent brick-and-concrete construction. "Double-wing" container units do not require heavy concrete foundations; they can be installed simply using grade beams or foundation pads. During the off-season, they can be folded up and relocated to other campsites or placed in centralized storage. Common locations for these units include campsites in Australia, New Zealand, North America, Europe, and Southeast Asian islands.

Seaside/Mountain Vacation Cabins & Weekend Villas

Suitable as temporary residences on private land or vacation plots; some clients utilize them for short-term rentals.

Support Facilities for Scenic Areas

Optimized functional layouts for visitor centers, ticket offices, souvenir shops, and destination cafés.

Large-scale Construction Site Offices & Management Dormitories

Applications: Mining sites, oil fields, road and railway projects, and overseas infrastructure projects located in remote areas.

Emergency Shelter Housing for Natural Disasters

Features: Rapid bulk transport via sea freight; quick deployment and immediate use upon arrival during earthquakes, floods, or hurricanes; equipped with integrated bathroom facilities and utility connections (water/electricity).

Frequently Asked Questions

Q1 What standard components are included?

Main steel structural frame, dual-wing expandable wall panels, roof, doors and windows, insulation, interior wall panels, pre-installed electrical wiring, flooring, bathroom, and kitchen. Optional features include a terrace, awning, custom wall colors, etc.

Q2 What is the packaging method?

The unit is secured in a retracted position and fully pre-assembled at the factory, eliminating the need for disassembly during shipping; rust-proof and waterproof protection is applied.

Q3 How long does installation take, and how many people are required?

It takes four skilled workers 3–4 hours to complete the unfolding, anchoring, and connection of doors, windows, and electrical systems. No large concrete foundation is required; a level, paved surface is sufficient.

Q4 How is the dual-wing container house transported internationally?

During transport, both wings fold inward to match the dimensions of a standard container. This compact design allows the entire unit to be loaded and shipped directly via standard 40HQ sea freight containers, lowering logistics costs.

Q5 What foundation preparation is required prior to delivery?

Heavy concrete pouring is not required. Simple concrete piers, grade beams, steel foundation pads, or even a hard-packed, level paved surface are completely sufficient to support the unit securely.

Q6 Can the unit be relocated and reused multiple times?

Yes. The modular structure allows both wings to be folded back inward whenever needed. It can be loaded, moved to a new site, and re-expanded with virtually zero structural loss, making it suitable for temporary or seasonal setups.
