PE PVDF Prepainted Aluminum Coil Color Coated Aluminum Coil Roll for Building Roof Wall Cladding Roller Shutter

1. Core Advantages

1. Dual coating system：PE polyester coating for indoor decoration, cost-effective, 8-10 years service life; PVDF fluorocarbon coating with super anti-UV & anti-salt spray, 20-30 years outdoor service life, perfect for coastal & high temperature areas.

2. Double baking process：Primer + topcoat double coating & double baking, compact paint layer, strong adhesion, 180° bending without paint crack or peeling, better quality than single coating products.

3. Rich color options：Full RAL solid colors, metallic silver/gold/bronze, transfer printing wood grain & stone grain. Custom color matching against customer sample within 3-5 days, batch color difference controlled within Grade 1.

4. Super weather resistance：PVDF coated coil passes 1000 hours neutral salt spray test, no rust, blister or fading; anti-chalking performance prevents surface powder falling under long sunlight.

5. Excellent processing performance：Good flexibility, supports bending, stamping, rolling forming, cutting, punching processing without damaging coating layer. Suitable for roller shutter, roof panel, curtain wall forming production lines.

6. Eco-friendly material：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 → acid & alkali washing → chromate passivation pretreatment → primary primer coating → first high temperature baking → top finish color coating → second baking & cooling → online coating thickness test → protective film lamination → rewinding → finished coil inspection → export packaging.

Full automatic closed production line, constant temperature & humidity workshop ensures consistent coating quality batch by batch.

FAQ

Q1: What's the core difference between prepainted aluminum coil and color aluminum sheet?

A: Prepainted coil is whole roll raw material, can be slitted into strip or cut into sheet; color aluminum sheet is finished flat plate cut from coil, ready for direct installation.

Q2: Which coating should I choose for seaside construction project?

A: Must select PVDF fluorocarbon prepainted aluminum coil, super anti-salt spray and anti-UV, 20-30 years service life for coastal environment.

Q3: How many colors can you produce for prepainted coil? Can you match custom color?

A: All RAL standard colors available. We can also develop special color based on your physical sample, make trial color sheet for confirmation before mass production.

Q4: Will the paint crack after bending the prepainted coil?

A: Our double coating & double baking process ensures excellent flexibility, 180° tight bending test without paint crack or peeling, normal forming processing will not damage coating.

Q5: What's the delivery time for custom color prepainted aluminum coil?

A: Standard stock colors ship within 5 days; custom color sample confirmation + mass production lead time 10-15 working days.
