Introduction

The 3105 aluminum coil (0.6–1.0 mm thickness, 100–1650 mm custom width, 25 μm food-grade PE moisture-proof layer) is the ultimate solution for frost-free, hygienic cold storage walls.

• Alloy 3105-H46: 15 % stronger than 3003, perfect rigidity for large panels.

• PE film + sealed edges: blocks 99.9 % water vapor, <0.01 g/m²·24 h permeation.

• Bright white or mirror finish options: easy cleaning, GMP/FDA compliant.
  Result: bone-dry walls at –40 °C, 70 % less cleaning time, 25 % faster installation than stainless steel.
