6. Coating and warranty terms. Gulf sun is the hardest test a coating faces. Ask which coil coating system is used and how many years the colour warranty runs in UAE exposure, and get the warranty conditions in writing. A 20 year warranty with impossible cleaning conditions is worth less than an honest 15.
7. Colour consistency. Ask how they guarantee batch to batch colour. Coil coated panels from one production run match. Mixed shipments do not. This is the single most common complaint we hear about imported stock.
8. Fabrication support. Can they cut, rout and fold, or connect you with fabricators who know their panel? A supplier with a fabrication network saves you from being alone between delivery and installation.
9. Project references you can visit. In the UAE the reference building is usually a short drive away. A supplier who names real projects is showing you a decade of their panels in the local climate.
10. Documentation without chasing. Technical Datasheets, test reports, approvals and colour charts should arrive the day you ask, not after three reminders. Try it before you order. Our own downloads page is public for exactly this reason.
