Brief Introduction

What is aluminium-zinc plated sheet

Aluminium-zinc plated sheet is a steel plate plating on the basis of zinc with the addition of aluminium (passivation protection), the general composition of 55% aluminium, 43.5% zinc, 1.5% silicon, with excellent resistance to atmospheric corrosion, corrosion resistance of galvanized sheet 2-5 times, but also has the high temperature corrosion resistance of aluminium plate, smooth surface, good appearance, but the formation of its plating and resistance to welding a little worse. In foreign countries generally about 40% of aluminium zinc plating used directly, about 60% of the plate is further as a colour coated substrate.

Uses: building roofs, walls, electrical cabinets, home appliances, automobiles, colour coated substrates, etc.

Aluzinc steel coils, also known as galvalume steel coils, are widely recognized for their exceptional corrosion resistance, durability, and aesthetic appeal. These properties make them highly versatile, leading to a broad range of applications across various industries. Here is a detailed overview of the primary applications and uses of Aluzinc steel coils:

1. Construction Industry

Roofing and Cladding:

- Residential Buildings: Aluzinc steel coils are extensively used in roofing and cladding for residential homes due to their long-lasting protection against the elements and attractive finish.

- Commercial Buildings: In commercial settings, they provide robust and aesthetically pleasing solutions for exterior walls and roofs, contributing to both durability and architectural design.

Architectural Panels:

- Facades: The material is used in creating modern facades for buildings, offering a sleek, metallic look that enhances the visual appeal of structures.

- Interior Design: Aluzinc steel is also used for interior panels in industrial and commercial spaces, providing a durable and stylish finish.

Structural Components:

- Framing: Aluzinc steel is used in the structural framework of buildings due to its high strength and resistance to rust and corrosion, ensuring longevity and structural integrity.

Base Metal Plate (Cold Rolled): It has the advantages of high strength, easy processing and economy, but it is prone to corrosion.

55% Alu-Zinc Steel Sheet: 55% Aluminium + 43.5% Zinc + 1.5% Silicon and other trace elements.

Alloy Layer: By forming a thin alloy layer between aluminium and iron, it inhibits the growth of brittle zinc-iron alloys and increases processability.
