K-House Purchase Checklist: Factory Records to Verify

What to Check Before Ordering K-House Units

Factory documentation helps you confirm that the K-House units you are buying match the agreed design, can be produced and inspected as planned, and are covered by clear delivery and warranty terms. Before placing an order, compare the supplier’s records with your required quantity and site conditions. Guangdong Uni-House lists factory self-inspection, a stated seven-day product delivery time, and a one-year warranty that excludes man-made damage. Ask the supplier to confirm which terms apply to your specific order.

Begin with the Order Configuration

Request drawings and a material schedule for the units being quoted. The product information describes a modular system based on 1K = 1,820 mm for length and width, and 1P = 950 mm for vertical height. It also lists galvanized steel framing, bolt connections that do not require on-site welding, sandwich-panel options, and floor systems with stated live-load ratings.

Have the factory document the exact configuration, including dimensions, frame thickness, panel core and thickness, flooring, doors, windows, and any pre-installed electrical fittings. Check that these details agree with the purchase agreement and drawings before production begins.

Verify Structural and Quality Evidence

The product information states wind resistance up to Grade 8, seismic resistance of Grade 7, and an anti-rust service life of at least 10 years. Treat these as product claims until the supplier provides relevant supporting test or inspection records. Confirm the conditions covered by those records and whether the proposed configuration is appropriate for the intended site.

Factory self-inspection is listed for the product, but the available information does not explain the inspection stages, acceptance criteria, or report format. Ask for the checklist and completed results for your order, and agree in writing how defects or other nonconformities will be addressed.

Check Capacity, Credentials, and Project Experience

Guangdong Uni-House Technology Co., Ltd. describes itself as a foreign-trade company under Guizu Group. Its profile says group factories support design, research and development, production, installation, and after-sales service. The company reports a 30,000-square-meter single-plant production base and annual capacity of 10,000 sets.

The company lists CE certification No. 3N240819.GUTQO66 for modular container-house products, including prefab K-house-related categories. Its experience record includes a 2,000-set worker-dormitory project for a coal mine in Indonesia. Use these details as background, and verify that the certification scope and project configuration are relevant to the units you plan to buy.

Compare the Records with Your Order

Delivery, Warranty, and Minimum Order Terms

The product record states a seven-day delivery time, while the company-wide business-model information lists 15 days. These figures may apply to different circumstances, so obtain a written schedule for your order that reflects its quantity and specifications. The product information also describes shipping in 20-foot or 40-foot high-cube ocean freight containers; clarify packing and delivery responsibilities in the contract.

The stated warranty lasts one year and excludes man-made damage. Before purchase, confirm when the warranty begins, which components it covers, what exclusions apply, and how to submit a claim. Minimum order information also differs: the company’s industry-trade integration model lists a minimum of one set, while the product-specific record states a minimum of 100 square meters. Ask which minimum applies to your purchase.

Frequently Asked Questions

What should I ask the factory for first?

Start with the order-specific configuration drawings and material schedule. Then request the self-inspection checklist and completed inspection results. Since the published product information does not describe the inspection process, confirm the factory’s criteria directly.

Which delivery time should I use?

The product information lists seven days, whereas the company business-model information lists 15 days. Ask the supplier to confirm the applicable lead time for your order and record the agreed schedule in the purchase documents.

What warranty is listed for K-House units?

The stated warranty is one year, excluding man-made damage. Confirm the coverage, exclusions, start date, and service process in writing before ordering.

Final Buyer Checklist

Before committing to K-House units, match the configuration and material records to the contract, review inspection evidence for the units being produced, and request support for structural-performance claims.
