K-House System Buying Guide: Technical Details to Verify

Choosing a K-House system requires more than reviewing the advertised appearance and price. Before signing an order, verify the structural frame, connection design, panel materials, floor construction, dimensions, electrical setup, corrosion protection, transport method, and installation requirements. The available product data refers to a folding container house, so confirm in writing that its specifications match the specific K-House system and configuration you plan to purchase.

What to Confirm Before Ordering

• Review the frame size, steel grade, tube thickness, connection method, hinges, and supplied fasteners.
• Select wall and roof panel cores based on insulation, fire performance, climate, and budget. The listed choices are EPS, rock wool, and polyurethane.
• Check the unit dimensions, internal clear height, flooring system, doors, windows, and factory-installed electrical components.
• Verify folding, stacking, shipping, unloading, and installation arrangements, including the stated installation time and labor requirements.
• Request project-specific documents covering inspection, warranty, electrical compliance, delivery terms, and final configuration.

Structural and Construction Details

Frame, steel, and connections

The stated standard unit size is 6055 mm long, 2435 mm wide, and 2800 mm high, providing a 2500 mm clear interior height. The primary columns are identified as 140 × 140 mm hot-dip galvanized square tubes, with wall thickness options of 2.0, 2.3, or 2.5 mm. Q355 high-strength steel is listed for export models. Since the final performance depends on the selected thickness and configuration, these items should appear clearly in the purchase specification.

The structure is designed for bolted installation without on-site welding. Its folding hinges are described as cast-steel components with anti-rust treatment. Ask for drawings or technical documents that show the connection points, hinge construction, bolt grades, and any limits on repeated folding or deployment.

Corrosion control and rainwater management

The listed surface-treatment sequence includes pickling, phosphating, and electrostatic powder coating, with a stated coating thickness of at least 60 μm. The roof beams include concealed drainage channels, while downpipes are integrated into the four corner posts. Confirm that these measures are included in the supplied unit and are appropriate for the local humidity, rainfall, coastal exposure, or industrial environment.

Panels, floor, doors, and windows

Wall and roof panels are described as sandwich panels with double-sided 0.4–0.5 mm anti-fingerprint, color-coated galvanized steel sheets. EPS is presented as a cost-effective insulated core, rock wool as the fire-resistance-oriented option, and polyurethane as a low-thermal-conductivity insulation solution. The available data does not include comparative test values, so request thermal, acoustic, fire, and density information when these properties affect approval or occupancy.

The floor consists of a galvanized square-tube support grid with either an 18 mm cement-fiber board or MGO board. Listed finish options include PVC flooring and anti-slip ceramic tile. The standard entrance is a 960 × 2100 mm steel security door. Windows are aluminum-alloy sliding units with tempered glass and fly screens. Confirm opening locations, hardware, glazing requirements, accessibility needs, and any custom layout before production begins.

Electrical, Transport, and Site Compatibility

Pre-installed electrical equipment is listed as LED ceiling lights, power sockets, a distribution box, and conduits embedded within the wall panels. The supplier states that configurations can comply with electrical standards in Southeast Asia, North America, and South America. This should not replace project-level verification: confirm voltage, frequency, breaker configuration, grounding, socket types, cable specifications, and inspection requirements for the actual destination.

The unit is described as foldable and stackable for transport. The stated installation time is 10–15 minutes for two workers without heavy machinery, but the complete site plan still needs to address unloading equipment, truck access, foundations, leveling, utilities, weather conditions, and installation scope. Construction camps, temporary post-disaster accommodation, and cultural or tourism commercial areas may require different layouts, finishes, fire measures, and service connections.

Specification Comparison for Buyers

Supplier Documentation and Commercial Checks

The product information states that the supplier performs factory self-inspection and provides a one-year warranty, excluding damage caused by people. Guangdong Uni-House Technology Co., Ltd. also lists CE certificate No. 3N240819.GUTQO66, covering several modular container house products, including folding containers. Because a certificate or company-level claim does not automatically prove compliance for every configuration, request the certificates, test reports, drawings, and inspection records associated with the exact system being ordered.

A recorded Indonesian mining-worker dormitory project involved 2,000 sets. This demonstrates reported project experience, but the case information does not include product-specific test results or the precise configuration used. Ask the supplier to identify which technical specifications, materials, and quality records applied to that project if it is relevant to your planned application.

Frequently Asked Questions

Are the listed folding container specifications automatically K-House specifications?

No. The supplied data describes a folding container house rather than a formally identified K-House system. Use it as a reference only, compare it with the exact K-House model, and obtain written confirmation of all differences before placing an order.

How should I choose between EPS, rock wool, and polyurethane?

EPS may suit projects prioritizing cost and basic insulation, rock wool is generally considered where fire resistance is important, and polyurethane offers low thermal conductivity. The available information does not provide full comparative test data, so base the choice on local regulations, climate, occupancy, fire strategy, and supplier documentation.

What delivery and payment terms are mentioned?

The product listing states a minimum order quantity of one set and a seven-day delivery time. Company-level commercial information lists a 15-day delivery period, a 50% advance payment with the balance due before shipment, and 40HQ or 20FT ocean-container transport. Confirm which terms apply to the selected product, quantity, destination, and production schedule.

Final Buying Recommendations

Before approval, request one consolidated, project-specific specification. It should identify the frame steel and thickness, panel core, floor materials, openings, electrical design, coating system, drainage, dimensions, inspection process, warranty coverage, packaging, installation scope, payment terms, and delivery schedule. Written confirmation is especially important because the available product description may not represent every K-House configuration.
