How to Compare Technical Specifications When Selecting a K-House Model

Selecting the right K-House model requires more than comparing appearance or floor area. Buyers should review the K and P modular system, structural frame, resistance to wind and earthquakes, sandwich panel composition, floor capacity, electrical layout, installation process, shipping method, reuse potential, lead time, warranty, and minimum order quantity. Together, these specifications show whether a prefab unit is suitable for the site, climate, intended use, and construction schedule.

Key Selection Criteria for a K-House

• Verify the modular dimensions. The system defines 1K as 1,820 mm for width and length, while 1P equals 950 mm in height. Configurations are available for one, two, or three floors.
• Review the frame and connection system, including galvanized steel sizes, corrosion treatment, Grade 8 wind resistance, Grade 7 seismic resistance, and the stated ability to be dismantled and rebuilt 5 to 8 times.
• Select the panel core and thickness according to insulation, fire safety, acoustic performance, and budget. EPS, rock wool, and PU cores are available in 50 mm, 75 mm, and 100 mm options.
• Consider the application before finalizing the model. K-Houses can be used for worker accommodation, site offices, construction camps, emergency housing, tourism projects, cultural facilities, and new rural villas.

Modular Dimensions and Layout Planning

K-House planning is based on two coordinated modules: K controls the building width and length, while P determines the vertical dimension. One K measures 1,820 mm and one P measures 950 mm. A single-story building is generally 3P high, a two-story building is 6P, and a three-story building is 9P.

The overall configuration can be expressed as Width (MK) x Length (NK) x Height (AP). M and N are whole-number K multiples, and A is normally 3, 6, or 9. Standard widths include 2K, 3K, 4K, and 5K, while the length can be extended by adding K modules.

For reference, the classic 3K x 12K x 6P model measures 5,460 mm x 21,840 mm x 5,380 mm. Before ordering, compare the proposed room sizes, corridors, stairways, number of floors, and site boundaries with the available modular combinations. This step helps prevent layout changes after production begins.

Frame Design and Site Resistance

The primary frame is built with galvanized C-channel steel columns measuring 80 x 160 mm. Depending on the design, the column wall thickness is 1.8 mm or 2.0 mm. The roof top purlin uses a C80 galvanized section with a 1.5 mm wall thickness, while the bottom base beam uses a 100 x 50 mm galvanized square tube with a 2.0 mm wall thickness. Cold-formed galvanized steel is also used for gable beams and connection components.

All major parts are joined with bolts, so on-site welding is not required. Pickling, phosphating, and electrostatic spraying are used as corrosion-control treatments, with a specified anti-rust service life of at least 10 years. The listed performance reaches Grade 8 wind resistance and Grade 7 seismic resistance. These figures still need to be checked against local building codes, exposure conditions, foundation design, and project-specific engineering requirements.

Panel Performance and Interior Comfort

Wall and roof sandwich panels are manufactured with 0.326 mm to 0.4 mm anti-fingerprint color-coated galvanized steel sheets. Their effective width is 950 mm, which corresponds to the modular planning system.

EPS is commonly selected when controlling project cost is important while maintaining thermal insulation. Rock wool is suitable where fire protection is a priority and is identified with an A1 non-combustible fireproof grade. PU offers stronger thermal retention and sound insulation. Available panel thicknesses are 50 mm, 75 mm, and 100 mm, so the choice should reflect the local temperature range, fire regulations, noise conditions, and energy requirements.

Floor, Roof, Doors, Windows, and Electrical Systems

The floor structure includes galvanized square-tube secondary beams spaced at 500 mm and a 15 mm cement fiberboard base. Typical finishes include 1.5 mm PVC vinyl flooring and anti-slip composite floor tiles. The stated floor live-load capacity is at least 180 kg per square meter, while the roof live-load capacity is at least 60 kg per square meter. Buyers should compare these values with occupancy levels, furniture, equipment, storage requirements, and any planned roof access.

A standard unit includes a 900 x 2,100 mm steel composite security door with a lock and anti-theft handle. Aluminum alloy sliding windows use tempered glass and integrated fly screens. Window widths can be adjusted according to the K module.

Electrical conduits are installed in advance inside the wall panels. The standard electrical package includes LED ceiling lights, power sockets, and a distribution box. The configuration can be adapted to electrical standards used in Southeast Asia, North America, and South America, but the voltage, frequency, protection devices, and final connection requirements should be confirmed before production.

Installation, Shipping, and Reuse

Logistics and installation should be evaluated as one part of the purchasing decision. The house is dismantled and flat-packed for shipment, helping reduce container usage and ocean freight volume. According to the listed installation information, two to three workers can assemble one single module in approximately two hours.

The system allows horizontal expansion and vertical stacking of up to three floors. It can also be relocated and used on multiple projects. The bolted construction supports repeated dismantling and assembly, with the stated reuse range reaching 5 to 8 cycles. For a temporary camp or phased development, confirm the available labor, lifting tools, foundation conditions, packing method, and future relocation route in advance.

Commercial Terms and Project Verification

Frequently Asked Questions

What dimensions must be confirmed before ordering?

Measure the usable site width and length against the K modulus, then match the required floor height to the P modulus. Confirm the planned story count as well. The listed system supports widths from 2K to 5K, K-based length extensions, and heights of 3P, 6P, or 9P.

How do EPS, rock wool, and PU panels differ?

EPS is positioned as a cost-conscious insulation choice. Rock wool is the preferred option when non-combustible fire performance is important, with an A1 fireproof grade. PU provides stronger heat preservation and sound insulation. The appropriate thickness, 50 mm, 75 mm, or 100 mm, depends on the climate and performance target.

What should be checked for a relocatable building?

Confirm the bolted connection system, flat-pack shipping dimensions, assembly workforce, container arrangement, lifting equipment, future site access, and foundation conditions. Also verify the expected number of dismantling and reassembly cycles. The listed system supports 5 to 8 cycles, horizontal extension, and stacking up to three floors.

Conclusion

A suitable K-House model should be selected by comparing the modular grid, structural resistance, panel properties, load capacity, electrical package, installation method, transportation plan, and reuse objectives. Commercial details are equally important. Guangdong Uni-House lists a minimum order quantity of 100 square meters, a 7-day delivery period, factory self-inspection, and a one-year warranty that excludes man-made damage.

The company also identifies CE certification No. 3N240819.GUTQO66 for modular container house products, including flat-pack, folding, expandable, Apple Cabin, and Space Capsule models. One reported cooperation project supplied 2,000 sets for mining workers' dormitories for an Indonesian local energy company, demonstrating the relevance of the system to large-scale accommodation and remote-site projects.
