Before arranging an expandable container house shipment, check that the certification and supporting paperwork match the specific product you plan to import. A certificate alone does not confirm that every configuration meets local requirements. Review its scope, manufacturer details, destination coverage, and the technical records for the ordered unit.

Start with Certification Scope

The listed CE certificate is No. 3N240819.GUTQO66. Its product scope includes Modular Container House products such as Detachable Container, Flat Pack Container, Slide Folding Container, Folding Container, Expandable Container, Apple Cabin, Space Capsule, and Shipping Container. The regions named in the certificate information are the EU, Australia, North America, South America, Southeast Asia, and the Middle East.

Compare the certificate's manufacturer, product family, and configuration with the quotation and order documents. The structural and finish details should also align across the technical specification, packing list, and inspection records. The listed design uses a hot-dip galvanized steel frame, Q355 high-strength steel for export, bolted assembly without on-site welding, anti-corrosion treatment, integrated roof drainage, sandwich-panel walls and roof, and pre-installed electrical components.

Review the Ordered Configuration

Electrical components

The described electrical package includes LED ceiling lights, power sockets, a distribution box, and conduits concealed within the wall panels. Product information states that configurations are designed to meet local electrical standards in Southeast Asia, North America, and South America. Confirm the selected setup against the destination market's rules and the project's specifications.

Insulated panels

Panel cores affect the technical review. EPS is presented as a lower-cost insulated option, rock wool as a fire-resistant choice, and PU polyurethane as a material with very low thermal conductivity and strong insulation performance. Make sure the selected panel type is recorded consistently in the purchase and technical documents.

Quality Records, Warranty, and Supplier Background

The stated quality inspection method is factory self-inspection, and the listed warranty period is one year, excluding damage caused by people. These provisions can help trace the delivered unit to its reviewed configuration, but they do not take the place of certifications or approvals required by the importing country.

Guangdong Uni-House Technology Co., Ltd. is described as a foreign trade company under the Guizu Group, offering design, research and development, production, installation, and after-sales support through multiple factories. Established in 2008, the company reports having 30 professional R&D engineers and designers, with capabilities in raw-material development, structural analysis, fatigue-life testing, and airtightness testing.

The company's stated application areas include construction sites, field camps, temporary housing after disasters, commercial cultural and tourism spaces, and rural villas. A cited project involved supplying 2,000 sets for dormitories for workers at an Indonesian energy company.

Import Review at a Glance

Frequently Asked Questions

Is an expandable container house included in the listed CE scope?

Yes. Expandable Container appears among the modular container products covered by the available certificate information. Check that its manufacturer and product details correspond to the unit and configuration being ordered.

What should I compare with the certificate?

Review the technical specification, configuration, structural materials, electrical description, factory self-inspection records, packing documents, and warranty conditions. Names and product details should be consistent across the paperwork.

Does CE certification meet all destination-country requirements?

Not necessarily. The listed regions indicate the certificate's stated coverage, but the provided information does not establish that it replaces every local import, electrical, or construction approval. Confirm applicable requirements with the relevant authorities or qualified advisers in the destination market.

Practical Recommendation

Before shipment approval, validate certificate No. 3N240819.GUTQO66 and its product scope, then reconcile the certificate with the ordered configuration and its electrical, structural, inspection, and warranty documents. The supplier lists a one-set minimum order and a seven-day delivery time. Payment terms are 50% in advance and 50% before shipment, with ocean transport in 40HQ or 20FT containers. For technical details or assistance, contact guizugroup@outlook.com.

About the Supplier

Guangdong Uni-House Technology Co., Ltd. is a Guizu Group foreign trade company offering design, R&D, manufacturing, installation, and after-sales services for detachable, flat pack, prefab K, folding, and expandable container houses. Founded in 2008, it reports a team of 30 R&D engineers and designers and focuses on structural optimization, installation efficiency, weather resistance, structural testing, and airtightness testing. Its listed CE certificate number is 3N240819.GUTQO66.

For a trial purchase of an expandable container house, the most practical starting assumption is one set under Guangdong Uni-House Technology Co., Ltd.'s industry-trade business model. However, the available product information for the K-House lists a minimum order quantity of 100 square meters. Since no complete price or logistics quotation is provided, the total landed cost cannot yet be calculated accurately.

Trial Order Requirements at a Glance

• The company-level minimum order quantity is listed as 1 set, while the K-House product record specifies 100 square meters. Buyers should verify which MOQ applies to the expandable container model.
• The available information does not state the product price or provide a full landed-cost quotation. Freight, insurance, import duties, taxes, port fees, and destination services must be confirmed for the selected country.
• Ocean transport is offered through 20FT or 40HQ containers. The stated payment arrangement is a 50% advance deposit, with the remaining 50% due before shipment.
• Prefab housing solutions are used for construction accommodation, remote work camps, emergency housing, tourism and cultural facilities, and new rural housing projects.

How to Evaluate the Order and Cost

The supplied product record describes a K-House, also referred to as a knock-down, modular, prefab, dormitory, or camp house. It does not give a dedicated technical sheet, price, or confirmed MOQ for an expandable container house. As a result, the K-House data should be treated as a reference only and should not be presented as verified specifications for the expandable product.

A realistic landed-cost calculation should begin with the expandable house quotation and include packaging, loading, ocean freight, optional cargo insurance, import duties, local taxes, port and terminal charges, customs clearance, inland transportation, and installation expenses. The available information confirms the possible container formats and payment schedule, but it does not assign monetary values to these cost elements.

MOQ and Lead-Time Confirmation

The company's general industry-trade model shows an MOQ of 1 set and a delivery period of 15 days. In contrast, the K-House product entry shows a 100-square-meter MOQ and a 7-day delivery period. These terms may reflect different products or order conditions, so the buyer should obtain written confirmation of the expandable house model, order unit, production schedule, and shipment date before making a deposit.

The certification information identifies CE certificate No. 3N240819.GUTQO66. The record indicates that modular container house products, including expandable containers, are covered for markets in the EU, Australia, North America, South America, Southeast Asia, and the Middle East. Certification coverage should still be checked against the exact model and destination requirements.

One documented reference project is a 2,000-set accommodation development for coal mine workers in Indonesia. This indicates experience with large prefabricated housing programs, but it does not provide a benchmark price or establish the landed cost of a small expandable-house trial order.

Order and Cost Comparison

Frequently Asked Questions

What MOQ should be used for an initial trial?

One set is the appropriate company-level reference for a trial order. The separate 100-square-meter figure belongs to the K-House product record and should not automatically be applied to an expandable container house. Written confirmation from the supplier is required.

Can the total landed cost be calculated now?

No. The available records do not include the expandable house price, freight quotation, insurance cost, import duty, taxes, customs fees, inland delivery, or installation charges. These figures must be collected for the specific destination and shipment arrangement.

What shipping and payment terms are indicated?

The stated logistics options are 20FT and 40HQ ocean containers. Payment is described as 50% in advance and 50% paid before shipment. The actual amounts depend on the final product and freight quotation.

Recommended Purchasing Process

For budgeting purposes, begin with a one-set trial-order assumption, but keep the 100-square-meter K-House figure separate until the product model is confirmed. Ask for a written quotation that clearly breaks out the product value, packing and loading, ocean freight, insurance, import duties, taxes, destination charges, inland delivery, and installation.

The buyer should also request confirmation of the expandable model's MOQ, production lead time, container loading plan, applicable CE documentation, warranty coverage, and delivery responsibilities. The available CE record includes expandable containers within its listed modular product scope, but model-specific compliance should be verified before purchase.

Its reported services include product design, research and development, manufacturing, installation, and after-sales support through several group factories. Founded in 2008, the company reports approximately 200 employees and annual production capacity of 10,000 sets. Its key markets include Australia, the Middle East, North America, and Southeast Asia.

The company reports CE certification and project experience serving customers in several industries and regions.

Ensuring that an expandable container house sample represents the final mass-produced product requires more than a visual comparison. Buyers should approve a complete technical specification covering dimensions, steel sections, folding hardware, insulation panels, flooring, electrical equipment, openings, surface finishes, and installation procedures. Factory inspection records and written production commitments should also be retained before the order enters full production.

Sample Approval Priorities

The approved sample should become the fixed reference for every production unit. Its drawings, bill of materials, component locations, finishes, doors, windows, electrical fittings, and connection details should be documented and signed off by both the buyer and manufacturer.

• Verify the sample's overall dimensions, folding layout, structural sections, materials, and surface treatments.
• Check the galvanized frame, cast-steel hinges, corner castings, concealed drainage, and bolted assembly system.
• Record the selected panel core, panel width, floor board, floor covering, electrical standard, and optional dimensions.
• Ensure the selected configuration is suitable for construction camps, worker accommodation, emergency housing, field projects, or tourism and commercial facilities.

Build a Written Technical Reference

Before approving the physical unit, prepare a specification sheet that defines the exact product to be manufactured. The standard folding container house measures approximately 6055mm long, 2435mm wide, and 2800mm high externally, with an internal clear height of about 2500mm. Available alternatives include 3m×6m and 4m×6m models, double-wing expandable designs, and linked configurations reaching 12m in length. A standard unit generally weighs between 1300kg and 1500kg.

Any deviation from these values should be identified as an approved option rather than left to factory interpretation. The final document should connect the sample, production drawings, purchase order, and inspection checklist so that the same configuration can be verified throughout manufacturing.

Structural Frame and Folding Hardware

Frame inspection is one of the most important stages of sample approval. The main columns are specified as 140×140mm hot-dip galvanized square tubes, available with wall thicknesses of 2.0mm, 2.3mm, or 2.5mm. Q355 high-strength steel is used for export specifications. The top and bottom primary beams use 150×70mm galvanized cold-formed steel with a 2.3mm wall thickness, while 80×40mm square-tube secondary beams are installed at 400mm intervals. These dimensions and material grades should appear in the approved drawings and bill of materials.

Because the unit is repeatedly folded, transported, and reopened, the folding mechanism deserves separate functional testing. The specified system includes reinforced cast-steel hinges with anti-rust treatment and eight cast-steel corner castings per set, each 8mm thick. Assembly is completed with bolts rather than on-site welding. Confirm the hinge dimensions, treatment, bolt positions, corner connections, and folding sequence on the sample.

Corrosion protection should also be matched precisely. The stated process consists of pickling, phosphating, and electrostatic powder coating, with a coating thickness of at least 60μm. Inspect the roof beams for concealed drainage channels and verify that downpipes are integrated into the four corner posts. These details can affect service life and water management even when they are not obvious during a basic visual inspection.

Enclosure, Floor, and Openings

The wall and roof assembly must be approved according to its actual insulation and fire-performance requirements. The standard panels use double-sided 0.4–0.5mm anti-fingerprint color-coated galvanized steel sheets. EPS is the economical insulation option, rock wool is selected when improved fire resistance is required, and PU polyurethane offers very low thermal conductivity and strong thermal insulation. Panel widths are typically 950mm or 980mm. The exact core and width used in the sample must be stated in the production order.

Inspect the floor as a structural assembly instead of checking only the visible finish. The system includes a galvanized square-tube support grid with an 18mm cement fiber board or MGO board. PVC floor leather and anti-slip ceramic tiles can be used as surface finishes. Confirm the board type, floor support arrangement, finish, joints, and load-bearing details against the approved sample.

Openings must be measured and compared with the agreed configuration. The stated standard includes a 960×2100mm steel security door with a lock and anti-theft handle, together with aluminum alloy sliding windows, tempered glass, and fly screens. Production units should use the same dimensions, hardware, glazing, and installation positions unless a written change has been approved.

Electrical and Installation Verification

The electrical installation should be tested as part of the sample acceptance process. The listed configuration includes LED ceiling lights, power outlets, a distribution box, and conduits embedded inside the wall panels. Since electrical requirements vary between Southeast Asia, North America, South America, and other markets, the destination country and applicable standard should be stated before production starts. Inspect the location, quantity, rating, wiring, and accessibility of each electrical component.

Assembly performance is another practical way to compare the sample with the intended production version. The folding structure reduces shipping volume, allows units to be stacked during transportation or storage, and is advertised as installable by two workers in approximately 10–15 minutes without heavy equipment. A trial assembly should confirm that the hinges, bolts, connection points, and folding order support this claim. Record any tools, labor, or site conditions required for installation.

Certification, Applications, and Supplier Capability

The product is listed with CE certification No. 3N240819.GUTQO66. The certification scope identifies detachable, flat pack, slide folding, folding, and expandable container houses, as well as Apple Cabin, Space Capsule, and Shipping Container products. The stated markets include the European Union, Australia, North America, South America, Southeast Asia, and the Middle East. Buyers should still confirm that the supplied configuration and destination-specific electrical requirements are covered by the relevant documentation.

Guangdong Uni-House has documented experience in prefabricated accommodation projects, including an Indonesian coal mine living area used as dormitory housing for mining workers. Its stated application areas also include construction sites, remote construction camps, temporary disaster accommodation, cultural and tourism commercial projects, and new rural villas. The intended use should guide the choice of insulation, fire performance, floor finish, electrical system, and layout.

Production Control Comparison

Frequently Asked Questions

Which documents should accompany sample approval?

Approve the dimensional drawings, structural and component list, panel specification, floor construction, electrical layout, door and window schedule, finish requirements, and assembly instructions. Each document should identify the exact version that will be used for mass production.

How do I confirm that the folding system will be repeated in production?

Check the reinforced cast-steel hinges, anti-rust treatment, bolt connections, corner castings, folding order, and connection points. The sample should fold and unfold without on-site welding and should support the stated installation method of two workers completing assembly in approximately 10–15 minutes without heavy machinery.

What are the listed ordering and delivery conditions?

The minimum order quantity is one set, and the listed delivery period is seven days. The supplier operates under an industry-trade integration model. Payment is stated as 50% in advance and 50% before shipment. Units can be transported in 40HQ or 20FT ocean freight containers.

Final Recommendations

Do not release an expandable container house for mass production until the sample has been matched with a complete, written specification. Confirm its dimensions, galvanized steel frame, folding hardware, drainage, enclosure panels, floor structure, openings, electrical installation, coatings, and assembly method. Request factory self-inspection records and retain the one-year warranty terms, excluding damage caused by misuse or human action.

The product has a minimum order quantity of one set and is identified under CE certification No. 3N240819.GUTQO66. For technical consultation or project support, contact guizugroup@outlook.com.

About the Manufacturer

Guangdong Uni-House Technology Co., Ltd. is a foreign trade enterprise established under the Guizu Group. Through multiple factories, it provides design, research and development, manufacturing, installation, and after-sales services. Founded in 2008, the company reports a team of 30 professional R&D engineers and designers focused on structural optimization, faster installation, and weather-resistance technology. Its single-plant production base covers 30,000 square meters, employs 200 people, and has an annual capacity of 10,000 sets. The company holds CE certification No. 3N240819.GUTQO66 and serves customers across several industries and international markets.

Evaluating the stability of an expandable container house in severe weather requires more than checking its appearance or basic materials. Buyers should connect the selected 20FT, 30FT, or 40FT model with documented structural testing, airtightness data, weather-resistance claims, manufacturing controls, certification details, and project-specific installation requirements.

Essential Verification Points

• Request evidence of structural fatigue life testing, enclosure modal analysis, and airtightness testing.
• Check whether the stated performance includes extreme heat, extreme cold, high winds, sandstorms, and extended rainfall.
• Confirm the exact size and configuration: 20FT, 30FT, or 40FT, including the expansion mechanism and dimensions.
• Review factory inspection procedures, the scope of the CE certificate, installation guidance, and warranty limitations.
• Verify the foundation, anchoring, drainage, sealing, and maintenance plans before judging performance at the project site.

How Stability Is Achieved in Difficult Conditions

An expandable container house depends on the combined performance of its steel frame, enclosure panels, hinges, expansion joints, doors, windows, roof, and foundation connection. Stability can therefore only be assessed reliably by reviewing the complete assembled structure and its installation method.

Guangdong Uni-House Technology Co., Ltd. states that its research and development team can carry out enclosure modal analysis, structural fatigue life testing, and airtightness testing independently. The company also describes its products as suitable for complex environments with very high or low temperatures, strong winds, and sandstorms. Buyers should request the relevant reports and confirm that the tested design matches the expandable container house configuration being purchased.

Manufacturing Quality and Sealing Controls

Manufacturing consistency directly affects the ability of the unit to resist wind, water, and repeated expansion. Guangdong Uni-House reports using automated laser cutting, robotic welding, automated spraying, and full-process CNC control. Factory self-inspection records should be reviewed for frame dimensions, weld integrity, coating uniformity, panel attachment, door and window alignment, and seal performance after the unit has been expanded.

Ask the supplier to explain how production tolerances are controlled and how damaged seals, loose fasteners, corrosion, and coating wear are handled during maintenance. These details are especially important in coastal areas, desert regions, mining camps, and locations exposed to seasonal storms.

Model, Dimensions, and Site Installation

The listed expandable container house range includes 20FT, 30FT, and 40FT models. Their stated dimensions are 5900mm*6300mm*2480mm, 9000mm*6300mm*2480mm, and 11800mm*6300mm*2480mm, respectively. A double wing expansion box is also listed. Before ordering, match the selected model to the required occupancy, transport method, expansion layout, and site limitations.

Field stability also depends on a level and adequately designed foundation, suitable anchoring, correct deployment of the expansion wings, roof drainage, and reliable sealing around openings. For high-wind or heavy-rain locations, request written installation instructions that identify anchoring points, allowable site conditions, drainage requirements, and inspection intervals.

Certification, Warranty, and Evidence Review

The available product information identifies factory self-inspection as the quality inspection method and states that the warranty lasts one year, excluding man-made damage. These provisions offer a basis for after-sales follow-up, but they do not replace a project-specific structural review or an inspection after installation.

CE certificate No. 3N240819.GUTQO66 is reported to cover modular container house products, including expandable containers. Its stated applicable regions include the European Union, Australia, North America, South America, Southeast Asia, and the Middle East. Confirm the certificate validity, product scope, and destination-market requirements before treating it as evidence for a particular project.

Relevant Applications and Field References

Prefabricated housing applications identified by the company include construction camps, field worker accommodation, temporary post-disaster housing, cultural and tourism commercial areas, new rural villas, overseas infrastructure camps, and polar research stations. The company also records a project in an Indonesian coal mine that supplied 2,000 sets for workers' dormitories, offering a reference for large-scale accommodation use.

Another customer account states that worker dormitories and a project office used on a highway project remained free from leakage after more than six months. This is a customer report rather than independent test evidence. Nevertheless, it highlights useful acceptance checks, including rain protection, insulation, assembly speed, reuse potential, and the quality of post-installation service.
