AZ70 Green AFP Galvalume Steel GL 55% Aluzinc Steel Roof Panels

Used For Stone Coated Tiles Villa Roof DX51D ASTM A792M S280GD

1. Introduction

Aluzinc steel coil, also known as Galvalume, is extensively used in the production of stone-coated metal roof tiles. This material choice is driven by its superior performance characteristics compared to traditional galvanised steel. Stone-coated metal roof tiles are known for their durability, aesthetic appeal, and ability to withstand extreme weather conditions, making Aluzinc steel an ideal substrate for this application.

2. Why Aluminum-Zinc Coated Steel is Widely Used in Construction

1. Longevity: The aluminum-zinc coating significantly increases the lifespan of the steel, making it a cost-effective solution over time.

2. Low Maintenance: Buildings constructed with aluminum-zinc coated steel require less maintenance due to the material's resistance to rust and corrosion.

3. Aesthetic Appeal: The coating provides a smooth, shiny finish that can enhance the visual appeal of buildings.

4. Fire Resistance: Aluminum-zinc coatings offer better fire resistance compared to other coatings, providing an added safety feature.

5. Energy Efficiency: The reflective properties of the coating help in reducing heat absorption, thereby improving the energy efficiency of buildings.

3. Characteristic of Aluminium-Zinc Plated Steel (Galvalume):

- Corrosion Resistance: Aluminium-zinc plated steel offers superior corrosion resistance, three times that of pure galvanized steel. This is due to the formation of a dense aluminium oxide layer that prevents further corrosion.

- Aesthetics: It features attractive zinc flowers on the surface, making it suitable for use as building exterior panels.

- Designation: AZ150 is a common abbreviation for aluminium-zinc plated steel, indicating a specific coating weight.

- Durability: The aluminium component provides excellent protection against chemical corrosion and physical reactions, maintaining the keel's appearance and preventing rust over time.

- Field Testing: Aluminium-zinc plated steel has undergone over 20 years of outdoor exposure tests in various atmospheric conditions, proving its superior edge protection compared to galvanized steel.

Heat Reflectivity:

- Aluminium-zinc plated steel has twice the thermal reflectivity of galvanized steel, making it an excellent thermal insulator. This property enhances its suitability for applications where heat reflection is beneficial.
