Product Description

Aluminum Alloy 3003 Aluminum Coil for Refrigerator Back Panel

Thickness 0.35–0.5 mm | Width 1240 mm | PE Coating

Product Overview

The 0.35-0.5 mm 3003 PE coated aluminum coil is the global mainstream specification for refrigerator back panels (condenser guards, rear covers, or structural back sheets) among tier-1 appliance manufacturers.

Optimal Balance Achieved:

Adequate structural rigidity for large refrigerator bodies

Maximum weight reduction for energy efficiency and logistics

Outstanding heat dissipation from condenser coils

Cost-effective PE coating for kitchen humidity protection

Superior Material Properties

Compared to 1100 (softer) or 5052 (stronger but more expensive), 3003 aluminum alloy offers:

20% higher strength than 1100 for better dent resistance

Thermal conductivity ~160-170 W/m*K for fast condenser heat transfer

Excellent PE coating adhesion and long-term color stability

Advanced Coating System

18-25 μm high-durability polyester (PE) coating

Double-layer baking (primer + topcoat)

Standard colors: RAL 9003 signal white / RAL 7035 light gray

Warranty: 20-25 years indoor corrosion and color stability
