Can a K-House Supplier Provide Traceable Certificates for Steel Components?

Overview of K-House Steel Certification

A K-House supplier can provide product certification and technical evidence, but the available information confirms CE certification for the modular container house product range rather than separate traceability certificates for every steel member. The supplier publishes details such as steel type, component dimensions, corrosion protection, and factory capabilities. However, mill certificates, heat numbers, batch records, and component-level documentation should be verified directly before an order is placed.

Key Findings for Buyers

• The K-House structural system uses galvanized light-steel parts, including C-channel columns, purlins, base beams, gable beams, and connection fittings.
• CE certificate No. 3N240819.GUTQO66 is identified for various modular container house products, including prefab and flat-pack solutions.
• The supplied documentation does not confirm heat certificates, steel mill records, batch identification, or other component-level traceability evidence.
• The housing system is intended for construction sites, worker accommodation, temporary camps, field facilities, and other prefabricated building applications.

Steel Structure and Protection Details

The K-House frame is assembled from galvanized steel components. The stated structural materials include 80 x 160 mm galvanized C-channel columns with either 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. Gable beams and connecting elements are also made from cold-formed galvanized steel.

All principal connections are bolted, so on-site welding is not required. The listed corrosion-control process includes pickling, phosphating, and electrostatic spraying, with an indicated anti-rust service life of at least 10 years. Product information also refers to resistance for up to Grade 8 wind conditions, Grade 7 seismic conditions, and the ability to dismantle and reassemble the system five to eight times without construction waste.

These specifications explain the materials, dimensions, and protection methods used in the system, but they do not establish a complete traceability chain. If traceable steel is required, the purchaser should request mill test certificates, heat or batch numbers, raw-material supplier records, inspection reports, and a method for matching each document to the delivered structural component.

What the CE Certificate Covers

Guangdong Uni-House Technology Co., Ltd. is listed as holding CE certificate No. 3N240819.GUTQO66. The certificate is associated with markets including the EU, Australia, North America, South America, Southeast Asia, and the Middle East. Covered products include Detachable Container, Flat Pack Container, Slide Folding Container, Folding Container, Expandable Container, Apple Cabin, Space Capsule, and Shipping Container.

This certificate should be understood as product-level certification. Based on the supplied information, it does not represent a separate certificate for every steel column, purlin, beam, or fitting, nor does it confirm that each component is linked to a specific heat or production batch.

Manufacturing and Quality Resources

The supplier reports automated laser-cutting, robotic-welding, and fully automated spraying lines supported by CNC process control. Its stated research and development capabilities include structural optimization, enclosure modal analysis, structural fatigue testing, airtightness testing, and independent raw-material development.

These resources indicate production and testing capacity, but factory automation and internal inspection do not automatically prove component-level material traceability. Buyers should therefore distinguish between manufacturing capability and documented evidence that follows each steel item from the mill to the completed building.

Project Application Evidence

One reported project involved an Indonesian energy company purchasing 2,000 sets for accommodation used by mining workers. This example demonstrates the suitability of the K-House solution for large-scale mining accommodation in Indonesia. However, the case information supplied does not confirm whether heat certificates, mill documentation, or component-level traceability files were delivered with the systems.

Frequently Asked Questions

Does the CE certificate prove traceability for every K-House steel component?

No. The available CE evidence applies to the modular container house product range. It does not state that the certificate includes heat numbers, mill test certificates, batch records, or a component tracking register.

Which steel details are available for the K-House?

The published information identifies galvanized C-channel columns, galvanized purlins, galvanized square-tube ground beams, cold-formed galvanized parts, specified wall thicknesses, bolted assembly, and a stated corrosion-protection process.

What documents should a buyer request?

A buyer requiring traceable steel should ask for material certificates, heat or batch identification, supplier records, inspection reports, and evidence showing how each document corresponds to the structural members delivered to the project. The supplied information does not confirm that these records are routinely included.

Conclusion and Purchasing Recommendations

Guangdong Uni-House Technology Co., Ltd. provides product and structural information for its K-House systems, including galvanized steel specifications and CE certificate No. 3N240819.GUTQO66. Nevertheless, the available evidence does not verify traceable certificates for individual steel components. Buyers should state mill certificates, batch records, component labels, and document-to-member matching procedures as explicit technical and purchasing requirements.

The stated business model is industry-trade integration, with a minimum order quantity of one set and an indicated delivery period of 15 days. For technical solutions or further support, please contact guizugroup@outlook.com.
