How to Evaluate K-House Specifications Before Selecting a Modular Model

Selecting the right K-House model requires more than checking the floor area and purchase price. Buyers should review the modular sizing system, structural frame, environmental resistance, sandwich panel performance, floor capacity, electrical layout, assembly process, logistics, reuse potential, delivery schedule, warranty terms, and minimum order quantity. Comparing these factors helps ensure that the selected prefab house suits the site, climate, intended use, labor resources, and project timeline.

Selection Priorities at a Glance

• Start with the K and P sizing system. One K represents 1,820 mm in the length and width directions, while one P represents 950 mm in height. The system can be configured for one, two, or three floors.
• Review the complete structural specification, including galvanized steel member sizes, bolted connections, corrosion treatment, Grade 8 wind resistance, Grade 7 seismic resistance, and the stated ability to be dismantled and rebuilt 5 to 8 times.
• Choose the panel material and thickness according to thermal performance, fire safety, acoustic control, and budget. Available cores include EPS, rock wool, and PU in 50 mm, 75 mm, and 100 mm options.
• Relate the technical configuration to the planned application, such as worker accommodation, site offices, construction camps, emergency housing, tourism facilities, or new rural residences.

Modular Planning and Building Dimensions

The K-House design is based on two coordinated modules. The K module defines the building length and width at 1,820 mm per unit, while the P module determines height at 950 mm per unit. A standard single-story structure is 3P high, a two-story structure is 6P, and a three-story structure is 9P. The overall configuration can therefore be expressed as Width (MK) x Length (NK) x Height (AP), with M and N representing whole-number K multiples and A representing 3, 6, or 9.

Typical widths are available in 2K, 3K, 4K, and 5K, while the length can be extended in additional K increments. One listed standard model is 3K x 12K x 6P, with overall dimensions of 5,460 mm x 21,840 mm x 5,380 mm. Before ordering, compare these limits with the site boundary, room sizes, corridor arrangement, staircase position, required number of floors, and any plans for future expansion.

Frame Engineering and Site Resistance

The primary frame consists of 80 x 160 mm galvanized C-channel steel columns. Depending on the configuration, the column wall thickness is 1.8 mm or 2.0 mm. The roof top purlin uses C80 galvanized steel with a 1.5 mm wall thickness, and the bottom foundation 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 connecting components.

All major members are joined with bolts, allowing the house to be assembled without site welding. Pickling, phosphating, and electrostatic spraying are used as part of the corrosion-protection process, with a specified anti-rust service life of at least 10 years. The structure is rated for wind loads up to Grade 8 and seismic resistance up to Grade 7. These stated values should still be checked against local building codes, foundation conditions, wind exposure, seismic zoning, and the project engineer's calculations.

Panels, Floors, and Interior Services

Exterior wall and roof panels are made with 0.326 mm to 0.4 mm anti-fingerprint, color-coated galvanized steel sheets and have an effective width of 950 mm. EPS is generally positioned as a cost-conscious insulation choice, rock wool offers an A1 non-combustible fire rating, and PU delivers stronger thermal retention and sound-control performance. Panel thicknesses of 50 mm, 75 mm, and 100 mm allow the envelope to be matched to the required climate and performance level.

The floor assembly uses galvanized square-tube secondary beams spaced at 500 mm intervals, topped with a 15 mm cement fiberboard base. Finish options include 1.5 mm PVC vinyl flooring and anti-slip composite tiles. The stated floor live-load capacity is at least 180 kg per square meter, while the roof live load is at least 60 kg per square meter. Confirm these figures against occupancy density, storage needs, furniture, equipment, and any intended roof access.

Standard openings include a 900 x 2,100 mm steel composite security door fitted with a lock and anti-theft handle. Aluminum alloy sliding windows use tempered glass and integrated fly screens, and their width can be adjusted to suit the K-module arrangement. Electrical conduits are embedded in the wall panels before delivery, with LED ceiling lights, sockets, and a distribution box included. Electrical components can be adapted for power standards used in Southeast Asia, North America, and South America.

Assembly, Transport, and Reuse

Logistics and installation are closely connected in a relocatable building project. The K-House is dismantled and flat-packed for shipment, helping reduce container volume and ocean freight demand. According to the listed installation information, two or three workers can assemble one single module in approximately two hours. The system can be extended horizontally, stacked to three stories, moved to another location, and reused through repeated disassembly and reassembly.

For a temporary or phased project, buyers should confirm the available installation crew, lifting and unloading equipment, foundation preparation, container loading plan, transport route, and future relocation conditions. The stated reuse range is 5 to 8 assembly cycles, although actual service life will depend on handling, storage, site conditions, and maintenance.

Commercial Terms and Application Fit

The listed commercial information includes factory self-inspection, a one-year warranty that excludes man-made damage, a minimum order quantity of 100 square meters, and a stated delivery period of seven days. The supplier also lists CE certification No. 3N240819.GUTQO66 for modular container house products, including flat-pack, folding, expandable, Apple Cabin, and Space Capsule models. Buyers should request confirmation of the current production schedule, inspection documents, warranty coverage, and certification scope before placing an order.

K-Houses can be considered for worker dormitories, project offices, remote construction bases, post-disaster temporary housing, cultural and tourism facilities, and new rural villas. In one referenced Indonesian project, a local energy company purchased 2,000 sets for mining-worker accommodation. This example illustrates the relevance of transport efficiency, rapid assembly, repeat deployment, and horizontal expansion in large-scale workforce housing.

Frequently Asked Questions

What dimensions need to be confirmed before ordering?

Measure the usable site width and length against the K-module increments, then match the required storey height to the P system. The listed range includes widths from 2K to 5K, K-based length extensions, and total heights of 3P, 6P, or 9P. Room layout, corridors, stairs, setbacks, and service access should also be checked before finalizing the model.

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

EPS is presented as a more economical insulation solution with useful thermal performance. Rock wool is the preferred option where an A1 non-combustible fire grade is important. PU is suited to projects that place greater emphasis on heat preservation and sound insulation. The 50 mm, 75 mm, and 100 mm thickness options allow further adjustment to climate, code, and budget requirements.

What should be reviewed for a relocatable building?

Confirm the bolt-assembled structure, flat-pack shipping method, installation labor, unloading arrangement, container utilization, foundation conditions, and the dimensions of the next site. Also ask how the 5-to-8-time disassembly and reassembly specification is supported in practice, including component inspection, storage, replacement parts, and maintenance responsibilities.

Conclusion

The most suitable K-House model is the one whose dimensions, structural capacity, panel system, building services, logistics, and commercial terms align with the actual project requirements. Review local regulations and site conditions alongside the listed Grade 8 wind, Grade 7 seismic, floor-load, insulation, and reuse specifications.
