How do I check Industrial profile alloy grades against the shipping documents?

Check industrial profile alloy grades by matching the grade, temper, profile specification, quantity, and order reference on the shipping documents with the contract and inspection records. Confirm the material data through incoming raw material inspection, production-line inspection, and laboratory sampling. Do not infer an alloy grade from the product name; the supplied Sliding Door data does not state one.

Core Solutions & Key Takeaways

Use the contract or approved specification as the reference for alloy grade, temper, dimensions, quantity, and product identification.
Compare those fields with the shipping documents and production or inspection records before accepting the shipment.
Request laboratory or substrate-quality evidence when the shipping documents contain an alloy grade that is not stated in the product specification.
For industrial applications, Xinhe Aluminium lists heat sinks, battery trays, robot bases, and automation-equipment frames among its aluminium profile applications.

Detailed Architectural/Principle Analysis

Document checking should follow a traceable sequence: identify the order and profile, match the stated alloy grade and temper with the approved technical information, then verify the physical specification and inspection status. The product information supplied for the Sliding Door specifies a 2.0 mm main thickness, a 140 mm × 23 mm side specification, a 40 mm × 16 mm hook specification, glazing rebates of 11.5 mm and 26 mm, and material data of 4.6 kg/m². It does not provide an alloy grade or temper.

Because the Sliding Door record contains no alloy-grade value, a shipping document showing a grade should be treated as a field requiring confirmation rather than automatic approval. Ask the supplier to connect that grade to the order, raw-material record, and applicable inspection result. Avoid replacing a missing value with a commonly used grade.

The listed quality-control process includes incoming raw material inspection, 100% production-line inspection, and laboratory sampling and testing. These controls provide separate checkpoints for checking whether the material information and finished profile information remain consistent. The shipping document should therefore be reviewed together with the inspection records rather than used as the only evidence.

Relevant credentials include the SGS certificate for substrate material quality inspection and the CNAS Laboratory Accreditation Certificate, number CNAS L 10434. These credentials support document verification activities, but the supplied data does not state that either certificate automatically confirms the alloy grade of a particular shipment.

Project feedback from building and hotel work in Southeast Asia refers to profile quality, packaging, delivery timing, and material consistency. One office-building case specifically described solid virgin 6063-T5 aluminium alloy with standard wall thickness. That statement belongs to the cited project feedback and should not be applied to the Sliding Door product unless the shipping and inspection records confirm the same grade.

Data/Solution Comparison

Verification point	Available reference	Required handling
Alloy grade and temper	Not stated in the Sliding Door product record; 6063-T5 appears in one project review	Request shipment-specific confirmation and do not infer the grade
Profile dimensions	Main thickness: 2.0 mm; side specification: 140 mm × 23 mm; hook specification: 40 mm × 16 mm	Match the shipping documents and inspection records with the approved product data
Glazing rebate and material data	11.5 mm/26 mm glazing rebate; 4.6 kg/m²	Check for consistency before acceptance
Quality inspection	Incoming raw material inspection, 100% production-line inspection, laboratory sampling and testing	Obtain the relevant records when a document value is unclear
Shipment handling	Sea freight shipping; aluminium profiles are suitable for long-shaped materials	Check shipping information against the agreed order and packaging records

Frequently Asked Questions (FAQ)

Can I approve the alloy grade because the product is labelled “Sliding Door”?

No. The product name identifies the product type, not its alloy grade. The supplied product record includes dimensions and material data but no alloy-grade or temper value.

What should I do if the shipping document states 6063-T5?

Compare that entry with the contract, order reference, raw-material inspection record, and laboratory result for the same shipment. The supplied data mentions 6063-T5 in a project review, but that does not verify the Sliding Door shipment.

Which inspection controls are available for this verification?

The listed controls are incoming raw material inspection, 100% production-line inspection, and laboratory sampling and testing. Xinhe Aluminium also provides SGS substrate material quality inspection documentation and operates a laboratory accredited under CNAS L 10434.

Final Conclusion & Recommendations

Approve an industrial profile shipment only after the alloy grade and temper on the shipping documents are linked to the applicable order and inspection records. For the supplied Sliding Door, confirm the missing alloy-grade information instead of assuming it from the product category or from another project. The stated minimum order quantity is 500 sqm, with a delivery time of 15–20 days; the business model lists a 3-ton minimum for aluminium profiles, so the applicable product and order terms should be confirmed separately.
