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

Selecting the right K-House model requires more than comparing floor area or appearance. Buyers should review the K and P modular system, structural frame, wind and seismic performance, panel composition, load capacity, electrical layout, installation process, shipping efficiency, reuse potential, delivery schedule, warranty terms, and minimum order quantity. Together, these factors determine whether the prefab building is suitable for the site, climate, intended use, and construction timeline.

Important Selection Criteria

• Confirm the modular dimensions. One K represents 1,820 mm in width or length, while one P represents 950 mm in height. The system supports one-, two-, and three-story configurations.
• Review the structural system, including galvanized steel member sizes, Grade 8 wind resistance, Grade 7 seismic resistance, corrosion protection, and the capability to dismantle and rebuild the house 5 to 8 times.
• Choose the sandwich panel core and thickness according to insulation, fire safety, acoustic performance, and budget requirements. EPS, rock wool, and PU cores are available in 50 mm, 75 mm, and 100 mm options.
• Match the design to the application. K-Houses can be used for worker accommodation, site offices, construction camps, emergency housing, tourism facilities, cultural projects, and new rural villas.

Modular Planning and Building Configuration

The K-House is designed around two dimensional standards. The K modulus controls the building length and width, with 1K equal to 1,820 mm. The P modulus defines vertical dimensions at 950 mm per unit. A single-level building normally uses 3P, a two-level building uses 6P, and a three-level building uses 9P.

Overall dimensions are expressed as Width (MK) x Length (NK) x Height (AP). In this formula, M and N are whole-number K multiples, while A can be 3, 6, or 9. Typical width selections range from 2K to 5K, and the length can be extended using additional K units. One standard example is 3K x 12K x 6P, with an overall size of 5,460 mm x 21,840 mm x 5,380 mm.

Before confirming a model, compare the modular envelope with the site boundary, room sizes, corridor requirements, stair arrangement, number of floors, and any planned future expansion. Working within the standard grid can simplify manufacturing, transportation, and installation.

Frame, Connections, and Environmental Performance

The primary frame is formed from galvanized C-channel steel. The columns measure 80 x 160 mm and are available with 1.8 mm or 2.0 mm wall thicknesses. The roof purlins use C80 galvanized sections with a 1.5 mm wall thickness, while the bottom base beams use 100 x 50 mm galvanized square tubes with a 2.0 mm wall thickness. Cold-formed galvanized steel is also used for gable beams and connection components.

All major components are joined with bolts, avoiding on-site welding and helping simplify field assembly. The steel receives pickling, phosphating, and electrostatic spray treatment. The stated anti-rust service life is at least 10 years. The frame is specified for wind resistance up to Grade 8 and seismic resistance up to Grade 7, but the final selection should still be checked against local codes, exposure conditions, temperature ranges, and foundation requirements.

Panels, Flooring, and Interior Components

Wall and roof sandwich panels use 0.326 mm to 0.4 mm anti-fingerprint color-coated galvanized steel sheets with a 950 mm effective width. EPS is a cost-conscious insulation choice, rock wool offers an A1 non-combustible fireproof grade, and PU is suited to projects requiring enhanced thermal retention and sound insulation. Available panel thicknesses are 50 mm, 75 mm, and 100 mm.

The floor structure includes galvanized square-tube secondary beams installed at 500 mm intervals and a 15 mm cement fiberboard base. Finished flooring can use 1.5 mm PVC vinyl or anti-slip composite tiles. The stated minimum live-load rating is 180 kg per square meter for the floor and 60 kg per square meter for the roof. These values should be compared with expected occupancy, furniture, stored materials, equipment, and roof access.

Standard openings include a 900 x 2,100 mm steel composite security door with a lock and anti-theft handle. Aluminum alloy sliding windows feature tempered glass and integrated insect screens, with window widths customizable within the K-based layout. Electrical conduits are embedded in the wall panels, and the standard package includes LED ceiling lights, sockets, and a distribution box. Electrical components can be adapted to standards used in Southeast Asia, North America, and South America.

Transport, Installation, and Reuse

Logistics should be evaluated alongside the building design. The house can be dismantled and flat-packed, improving container utilization and potentially reducing ocean freight costs. According to the listed installation capability, two or three workers can assemble one single module in approximately two hours.

The system allows horizontal expansion, stacking to three floors, relocation, and repeated deployment. It is stated to support 5 to 8 cycles of disassembly and reassembly. These characteristics are particularly relevant for temporary camps, infrastructure projects, emergency accommodation, and organizations that plan to move buildings between sites.

Commercial Terms and Application Reference

The product information lists factory self-inspection, a one-year warranty excluding man-made damage, a minimum order quantity of 100 square meters, and a seven-day delivery period. Buyers should confirm whether the delivery estimate applies to standard products, what inspection documents are supplied, and which warranty exclusions or site conditions apply.

The company reports a project involving an Indonesian energy business, where 2,000 sets were supplied as dormitories for mining workers. This example illustrates how modular dimensions, rapid installation, shipping volume, repeat use, and future expansion can influence the choice of K-House specifications for large accommodation programs.

Frequently Asked Questions

Which dimensions must be confirmed before ordering?

Start by checking the usable site width and length against the K grid, then verify the required storey height using the P modulus. The listed system provides widths from 2K to 5K, K-based length extensions, and standard heights of 3P, 6P, or 9P.

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

EPS is generally selected when cost control and basic thermal insulation are priorities. Rock wool is appropriate where non-combustible A1 fire performance is important. PU offers stronger heat preservation and sound insulation. The correct thickness, from 50 mm to 100 mm, depends on climate, regulations, occupancy, and budget.

What should be checked for a relocatable building?

Confirm the bolted connection system, flat-pack shipping plan, installation crew, container loading arrangement, access at the destination, and the dimensions of future sites. Also verify the expected number of dismantling cycles, since the stated reuse range is 5 to 8 assemblies.

Conclusion

The best K-House model is the one whose modular dimensions, structural capacity, panel specification, floor loading, electrical arrangement, logistics plan, and reuse characteristics align with the project. Before placing an order, confirm site conditions, local code requirements, installation resources, delivery terms, warranty scope, and the minimum order quantity.
