1. Warranty period
Warranty periods follow Quang Minh Aluminium's published policy for each product group and are stated on the product page or quotation (where applicable).
Finishing coat
The Jotun/PPG powder coating is warranted for up to 20 years against fading, peeling and abnormal deterioration, provided the product is installed, cleaned and used per the guidelines. This covers coating defects, not mechanical damage after installation.
Aluminium profiles & alloy
Extruded aluminium bars are guaranteed to the correct alloy grade (A6061/A6063/A6005S), T5 heat treatment, cross-section tolerance and thickness published for each system at the time of dispatch.
Accessories & gaskets
Accessories, hinges, locks and gaskets supplied are genuine, matched to the system and free of defects at delivery. Natural wear during use is not covered by the long-term warranty.
2. Warranty scope
Covered
- Material or fabrication defects from the factory
- Products not matching the agreed specification or quality grade
- Profiles bent, dented or with flaking coating at delivery (recorded on receipt)
- Functional failure under normal, rated use within the warranty period
- Incorrect or missing documents (CO/CQ, conformity certificates) — reissued free of charge
Note: Standard warranty terms apply when the product is installed, cleaned and used per the guidelines. Highly corrosive environments (coastal, chemical) may require a dedicated coating and separate terms — contact us for advice on the right solution.
3. Not covered by the warranty
The warranty does not apply to damage or deterioration caused by:
- Incorrect installation, handling or storage of the product
- Loads beyond the design rating, or installation and use contrary to instructions
- Exposure to corrosive environments or conditions beyond the product's design
- Natural wear of accessories and gaskets during use
- Physical damage, impact or scratches after delivery
- Modification, alteration or repair by an unauthorised party
