Prepainted Aluminium Stripe Color Coated Narrow Aluminum Strip Coil for Roller Shutter Door Decorative Edge Trim Lamp Housing Hardware Stamping

1. Core Advantages

1. Precision slitting processing：Imported alloy slitting knife, minimum slitting width 10mm, edge burr-free, width tolerance ±0.1mm, stable automatic feeding for customer stamping machines.

2. Stable coating & consistent color：Base coil completed double high-temperature baking before slitting, coating strong adhesion, no edge paint peeling. Matte & glossy surface optional, unified coating production line ensures zero obvious color difference between batches.

3. Two anti-corrosion coating options：Standard PE polyester coating for regular outdoor use; upgraded PVDF fluorocarbon stripe for coastal salt spray & chemical corrosive environment, anti-fade service life over 10 years.

4. Good forming performance：1060 O soft temper supports deep drawing & repeated bending; 3003 anti-rust alloy for long-term outdoor structural accessories, coating intact after all cold processing.

5. Mini coil customized design：Small inner diameter mini coil 50-500kg, match small automatic rolling shutter & stamping equipment, save storage space for small factories.

6. Eco-friendly paint material：Water-based non-toxic color coating, pass RoHS & REACH test, no heavy metal, safe for indoor furniture & lighting decoration.

2. Production Process

Full-width prepainted coil incoming inspection → uncoiling → surface defect online detection → precision slitting → constant tension rewinding into mini stripe coil → plastic end cap protection → multi-layer anti-rust film wrapping → pallet stacking & export packaging.
