Custom RAL Color Coating Aluminum Prepainted Aluminum Coil Sheet Strip for Construction Decoration Roller Shutter

1. Core Advantages

1. Full product forms one-stop supply：Cover three main forms: prepainted aluminum coil (raw roll), color flat sheet (cut finished plate), prepainted narrow strip (slitted mini coil). Unified coating production line, same color system, no batch color difference, save customers multi-supplier procurement cost.

2. Dual coating grade selection：PE polyester coating for indoor low-budget projects, cost-effective, 8-10 years service life; PVDF fluorocarbon coating with super anti-UV & anti-salt spray, 20-30 years outdoor service life, suitable for coastal & heavy industry areas.

3. Rich surface effects：Solid matte/gloss color, metallic silver/gold/bronze, transfer printing wood grain, marble stone grain, camouflage grain. All RAL standard colors covered, custom special color matching available.

4. Double baking process guarantee：Primer + topcoat double coating & double high temperature baking, compact paint layer, strong adhesion, 180° bending without paint crack or peeling, better weather resistance than single coating products.

5. Unified quality standard：All color coating aluminum products adopt same pretreatment and coating production line, coating thickness, adhesion, anti-aging performance completely consistent, convenient for customers matching use in one project.

6. Eco-friendly & durable：Water-based environmental paint, no formaldehyde & heavy metal, meets RoHS & REACH standards; aluminum substrate 100% recyclable, low carbon energy saving building material.

2. Production Process

Raw aluminum coil uncoiling → surface degreasing & cleaning → chromate passivation pretreatment → primary primer coating → first baking curing → top finish color coating → second baking cooling → online thickness & color detection → protective film lamination → different forms processing (coil rewinding / sheet cutting / strip slitting) → finished product inspection → export packaging.

Full automatic closed production line, constant temperature & humidity workshop ensures stable quality for every batch.
