K-House Steel Traceability: What Certificates Can the Supplier Provide?

A K-House supplier can provide product certification and technical evidence, but the available information confirms a CE certificate for the modular container house range rather than a separate traceability certificate for every steel member. The supplier publishes details about steel grades, component sizes, galvanizing, corrosion protection, and factory capabilities. However, buyers must verify the availability of mill certificates, heat numbers, batch records, and related inspection documents before placing an order.

Certification Scope and Main Findings

• The K-House structural system uses galvanized light-steel parts, including C-channel columns, purlins, ground beams, gable beams, and connection fittings.
• CE certificate No. 3N240819.GUTQO66 is identified for a range of modular container house products, including prefab and flat pack models.
• The supplied information does not confirm component-level records such as steel heat numbers, original mill certificates, or batch tracking documents.
• The system is intended for construction sites, worker accommodation, temporary camps, prefabricated housing, and similar applications.

Steel Structure and Production Details

The K-House frame consists of galvanized steel members manufactured in several profiles. The listed components include 80 x 160 mm galvanized C-channel vertical columns with 1.8 mm or 2.0 mm wall thickness, C80 galvanized purlins with a 1.5 mm wall thickness, and 100 x 50 mm galvanized square-tube ground beams with a 2.0 mm wall thickness. The gable beams and connection fittings are also made from cold-formed galvanized steel.

Installation is based on bolted connections, so on-site welding is not required. The stated surface-protection process includes pickling, phosphating, and electrostatic spraying, with an indicated anti-rust service life of at least 10 years. Product information also refers to performance for up to Grade 8 wind loads, Grade 7 seismic resistance, and five to eight cycles of dismantling and reassembly without construction waste.

These specifications explain the type, size, and treatment of the structural materials, but they do not establish a complete chain of custody for each steel component. If traceability is necessary, the purchaser should request mill test certificates, heat or batch identification, supplier delivery records, inspection reports, and a clear method for matching those documents to the delivered members.

What the CE Certificate Covers

Guangdong Uni-House Technology Co., Ltd. holds CE certificate No. 3N240819.GUTQO66. The certificate is listed for the EU, Australia, North America, South America, Southeast Asia, and the Middle East. Its product scope includes Detachable Container, Flat Pack Container, Slide Folding Container, Folding Container, Expandable Container, Apple Cabin, Space Capsule, and Shipping Container. This is evidence relating to the product range and should not be treated as proof that every steel component has an independent traceability certificate.

Manufacturing Capability and Project Evidence

The supplier reports automated laser cutting, robotic welding, fully automated spraying, and CNC control across the production process. Its research and development activities include structural optimization, enclosure modal analysis, fatigue-life testing, airtightness testing, and independent raw-material development. These resources support production quality and engineering development, but factory automation and testing capacity alone do not verify heat-level or batch-level traceability.

One documented project involved an Indonesian energy company purchasing 2,000 sets for accommodation at a mining workers' dormitory project. This example demonstrates the use of the K-House system in an Indonesian mining environment. However, the available project description does not confirm that heat certificates, mill documents, or component-level tracking files were included with the order.

Traceability Evidence Review

Frequently Asked Questions

Does the K-House CE certificate guarantee traceability for every steel part?

No. The certificate applies to the listed modular container house products. The available information does not say that it includes heat numbers, mill test certificates, batch histories, or a component identification system.

Which steel details are provided for the K-House system?

The published specifications identify galvanized C-channel columns, galvanized purlins, galvanized square-tube ground beams, cold-formed galvanized parts, wall thicknesses, bolted assembly, and corrosion-protection procedures.

What documents should a buyer request?

A buyer requiring traceable steel should request material certificates, heat or batch references, supplier records, inspection reports, and documentation showing how each record corresponds to the structural members delivered to the project. The current product information does not confirm that these records are automatically included.

Conclusion and Purchasing Recommendation

Guangdong Uni-House Technology Co., Ltd. provides substantial product and structural information for its K-House solution, including galvanized steel specifications, manufacturing details, and CE certification. Nevertheless, the available evidence does not demonstrate traceable certification for individual steel components. Buyers should include mill certificates, batch records, and component identification requirements in the technical specification, purchase contract, and inspection plan. The stated business model combines industry and trade integration, with a minimum order of one set and an indicated delivery period of 15 days.
