How to Verify Aluminium Profile Alloy Grades on Shipping Documents

To verify an industrial aluminium profile alloy grade, compare the shipping documents with the approved contract, technical specification, order reference, and inspection records. Check the alloy grade, temper, profile dimensions, quantity, and product identification as a connected set of information. Incoming material checks, production-line inspections, and laboratory testing should then be used to confirm the shipment. A product name alone is not proof of an alloy grade; the supplied Sliding Door information does not specify one.

Recommended Verification Process

Begin with the approved order or technical specification, which should be treated as the primary reference. Match the shipping document against the following items:

• Alloy designation and temper, if specified
• Profile dimensions, wall thickness, and section details
• Quantity, order number, and product identification
• Inspection status and related quality records

If an alloy grade appears on the shipping document but is absent from the approved product information, do not approve it automatically. Ask the supplier to provide shipment-specific evidence linking the stated grade to the raw-material batch and relevant test results.

Product Information That Must Be Confirmed

The available Sliding Door record provides several physical details, including 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. However, it does not identify an alloy grade or temper.

For this reason, a grade printed on the shipping paperwork should be handled as an item requiring confirmation. It must be connected to the applicable purchase order, raw-material inspection documentation, and laboratory report. Do not substitute a frequently used grade simply because it is common for a similar aluminium profile.

Use Quality Records as Supporting Evidence

Shipping documents should not be treated as the sole source of material verification. The listed quality system includes incoming raw material inspection, 100% production-line inspection, and laboratory sampling and testing. These stages create separate checkpoints for confirming that the supplied alloy information, profile dimensions, and finished-product records remain consistent.

Xinhe Aluminium also lists an SGS certificate for substrate material quality inspection and a CNAS Laboratory Accreditation Certificate, number CNAS L 10434. These documents support the credibility of the verification process, but the available information does not state that either certificate independently proves the alloy grade of a specific shipment. The applicable batch records and test results must still be reviewed.

Keep Project References Separate from Shipment Records

Feedback from building and hotel projects in Southeast Asia discusses profile quality, packaging, delivery performance, and material consistency. One office-building project refers to solid virgin 6063-T5 aluminium alloy with a standard wall thickness. That statement applies to the cited project only. It should not be used to approve the Sliding Door shipment unless the current order documents and inspection results confirm the same alloy and temper.

Verification Checklist

Frequently Asked Questions

Can the alloy grade be approved because the item is called a Sliding Door?

No. “Sliding Door” identifies the product category rather than the alloy composition. The supplied record includes dimensions and material data, but no alloy-grade or temper designation.

What if the shipping document lists 6063-T5?

Compare the entry with the contract, order number, raw-material inspection record, and laboratory result for the same shipment. Although 6063-T5 appears in one project review, that reference does not establish the grade of the Sliding Door shipment.

Which controls can support the review?

The available controls include incoming raw material inspection, complete production-line inspection, and laboratory sampling and testing. SGS substrate material quality documentation and the laboratory accreditation under CNAS L 10434 are also listed as supporting credentials.

Acceptance Recommendation

Accept an industrial aluminium profile shipment only when the alloy grade and temper shown on the shipping documents can be traced to the correct order and inspection records. For the supplied Sliding Door, the missing alloy information must be confirmed rather than inferred from the product name or another project example.

The stated minimum order quantity is 500 sqm and the delivery period is 15–20 days. The business model separately lists a 3-ton minimum for aluminium profiles, so the applicable product and order conditions should be confirmed before final approval.
