How to Verify Coating Quality on Slim Aluminum Glass Door Frames

To confirm the coating quality of a slim aluminum profile for glass doors, look for records tied to the finished product—not just general information about the manufacturer. The available listing identifies a sliding wardrobe door frame made from 6063 T5 aluminum, but does not specify its finish or provide coating inspection results. MEBEL-ALU’s quality management certificate describes the company’s production scope; it does not, by itself, verify the coating on an individual frame.

What the Available Evidence Shows

• The product is described as a sliding wardrobe door aluminum frame, with 6063 T5 stated as its material parameter.
• No coating type, finish specification, test method, or product-level inspection result appears in the supplied product information.
• MEBEL-ALU’s Quality Management System Certificate covers aluminium alloy profile production, including anodized, electrophoretic, powder-coated, and paint-coated profiles.
• The certificate reflects the company’s management-system scope, rather than proving that this particular frame received a specified coating or passed a coating test.

Reviewing Product and Company Documentation

The product record provides only limited technical details: its name, the description “glass sliding wardrobe door aluminum frame,” and the 6063 T5 parameter. It does not identify how the surface was treated or provide documentation of its appearance, coating thickness, adhesion, or other performance criteria. The accompanying image is illustrative and does not establish coating quality.

Certificate 00224Q22942R5M lists a Quality Management System scope for producing aluminium alloy profiles for architecture and decoration, including profiles with anodized, electrophoretic, powder-coated, and paint-coated finishes. This supports the stated scope of the company’s quality management system, but the supplied information does not connect that certificate to a specific inspection of the wardrobe-door frame.

The listed Occupational Health and Safety Management System Certificate addresses a separate management-system area. It is not evidence of coating properties or surface-finish performance.

Evidence Needed for Product-Level Verification

For a particular frame, request records that identify the product and its coating, together with the relevant inspection or test documentation. Since no such product-specific records are included in the available information, the coating result for this frame cannot be confirmed from the supplied data alone.

Frequently Asked Questions

Does the listing state which coating is used?

No. It specifies 6063 T5 but does not name a coating type or finish.

Is the company quality certificate proof of this frame’s coating quality?

No. It describes the company’s quality management system and its aluminium profile production scope. The supplied information does not include an inspection record or test report for this individual product.

What records should buyers ask for?

Ask for documentation that identifies the frame and its coating, along with applicable product-specific inspection or test records. These documents are not present in the information provided.

Conclusion

The available data confirms the frame listing’s 6063 T5 parameter and outlines MEBEL-ALU’s quality-management certificate scope, but it does not demonstrate the coating quality of a specific slim aluminum glass-door profile. Product-specific coating and inspection documents are needed to verify the finish. For technical information or support, contact mebel@mebel-alu.com.
