How to Verify Industrial Aluminium Profile Alloy Grades on Shipping Documents

Begin With the Approved Order Information

To verify an industrial aluminium profile shipment, compare the alloy grade, temper, profile dimensions, quantity, and order reference shown on the shipping documents with the approved contract and inspection records. The product name alone is not sufficient evidence of an alloy grade. In the supplied Sliding Door information, the profile specifications are listed, but no alloy grade or temper is provided.

• Use the contract or approved technical specification as the primary reference for grade, temper, dimensions, quantity, and product identification.
• Match each shipping-document entry with the purchase order, production records, and inspection results before accepting the material.
• Request shipment-specific laboratory or substrate-quality evidence if a shipping document includes an alloy grade that is missing from the product specification.
• For industrial projects, Xinhe Aluminium identifies heat sinks, battery trays, robot bases, and automation-equipment frames as aluminium profile applications.

Recommended Verification Sequence

1. Confirm the order and profile identity

Start by checking the purchase order number, customer reference, profile name, drawings, and approved specification. The information should identify the same product across the contract, packing list, bill of lading, material certificate, and quality records. Quantity and shipment details should also correspond with the agreed order.

2. Compare alloy, temper, and physical specifications

Next, compare the stated alloy grade and temper with the approved technical documents. Then check the profile dimensions, wall thickness, glazing details, unit weight, and quantity. A matching product name does not prove that the material has the required chemical composition or mechanical condition.

The supplied Sliding Door record states a main thickness of 2.0 mm, a side specification of 140 mm × 23 mm, a hook specification of 40 mm × 16 mm, glazing rebates of 11.5 mm and 26 mm, and material data of 4.6 kg/m². However, it does not state an aluminium alloy grade or temper.

3. Resolve missing or conflicting values

If the shipping document lists a grade that does not appear in the approved product record, treat the entry as information requiring confirmation. Ask the supplier to connect the declared grade to the specific order, incoming raw-material batch, production record, and relevant laboratory result. Do not fill in a missing value by assuming that a commonly used grade was supplied.

The quality-control process described for the product includes incoming raw-material inspection, 100% production-line inspection, and laboratory sampling and testing. These checkpoints should be reviewed together because they provide evidence at different stages of production. The shipping document should support the traceability chain, but it should not be the only basis for approving the alloy grade.

Certificates and Project Evidence

The available credentials include an SGS certificate for substrate material quality inspection and the CNAS Laboratory Accreditation Certificate, number CNAS L 10434. These documents can support the supplier's quality and testing system. They do not, based on the supplied information, automatically verify the alloy grade of a particular shipment. The applicable batch or test result must still be identified.

Project feedback from building and hotel work in Southeast Asia refers to profile quality, packaging, delivery schedules, and material consistency. One office-building review describes solid virgin 6063-T5 aluminium alloy with a standard wall thickness. That statement belongs to the cited project and should not be transferred to the Sliding Door shipment unless the order documents and inspection records confirm the same alloy and temper.

Verification Points at a Glance

Frequently Asked Questions

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

No. Sliding Door describes the product category rather than its alloy composition. The supplied record gives dimensions and material data, but it does not include an alloy-grade or temper designation.

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

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

Which inspection evidence should accompany the document review?

Request the incoming raw-material inspection record, the 100% production-line inspection record, and the applicable laboratory sampling or testing result. SGS substrate material quality documentation and the laboratory accreditation under CNAS L 10434 can provide additional support, but the records must relate to the material being shipped.

Conclusion and Purchasing Recommendations

Release an industrial aluminium profile shipment only when the alloy grade and temper on the shipping documents can be traced to the applicable order and inspection evidence. For the supplied Sliding Door, confirm the missing alloy information directly instead of deriving it from the product name or from an unrelated project reference.

The product information states a minimum order quantity of 500 sqm and a delivery period of 15–20 days. The broader business terms list a 3-ton minimum for aluminium profiles, so the governing quantity and delivery conditions should be confirmed for the specific order.
