What is Aluzinc Steel Coil?
Aluzinc steel coil, also known as aluminium-zinc coated steel, is a type of steel product that features a coating made from an aluminium-zinc alloy. This coating typically consists of 55% aluminium, 43.4% zinc, and 1.6% silicon. The combination of these metals in the coating provides the steel with enhanced properties, making it suitable for various industrial and construction applications.
Aluzinc steel coil is a premium coated steel product that offers significant advantages over traditional galvanized steel. Its superior corrosion resistance, excellent heat reflectivity, enhanced durability, and aesthetic appeal make it a preferred choice for a wide range of applications, including construction, roofing, siding, and industrial uses. The combination of aluminium and zinc in the coating ensures long-lasting performance, making Aluzinc steel coils a valuable material for demanding environments.
- Description: Coated with an alloy of aluminum and zinc, typically 55% aluminum, 43.4% zinc, and 1.6% silicon.
- Characteristics:
- Corrosion Resistance: Superior, often three times more than galvanized steel.
- Durability: High, with a lifespan that can exceed 50 years.
- Reflectivity: High thermal reflectivity, making it energy-efficient.
- Cost: Higher than galvanized steel, but offers better performance.
- Applications: Ideal for harsh environments, including industrial and coastal areas.
- Pros:
- Excellent corrosion resistance.
- Long lifespan and low maintenance.
- Cons:
- Higher initial cost.
- More limited availability.
1. Superior Corrosion Resistance: The aluminium content in the coating provides enhanced corrosion resistance, especially in harsh environments.
2. Heat Resistance: Better performance in high-temperature conditions due to the aluminium component.
3. Longer Service Life: The combined protective properties of aluminium and zinc result in a longer lifespan compared to regular galvanized steel.
4. Enhanced Reflectivity: The aluminium-zinc coating provides excellent reflectivity, making it suitable for roofing and siding applications where heat reflection is beneficial.
1. Corrugated Steel Tiles
- Description: These are traditional roofing sheets with a wavy pattern, offering good water drainage and aesthetic appeal.
- Applications: Used for industrial, commercial, and residential roofing.
2. Trapezoidal Steel Tiles
- Description: Featuring a trapezoidal shape, these tiles provide excellent strength and durability.
- Applications: Ideal for industrial buildings, warehouses, and large commercial structures.
3. Tile-Effect Steel Tiles
- Description: Designed to mimic the appearance of traditional clay or concrete tiles while providing the benefits of steel.
- Applications: Popular in residential buildings and commercial buildings for aesthetic purposes.
4. Standing Seam Steel Tiles
- Description: These tiles have a raised seam running vertically up the roof, providing a sleek, modern look and superior weather resistance.
- Applications: Used in contemporary residential buildings and high-end commercial projects.
5. Sandwich Panel Steel Tiles
- Description: Composed of a core insulating layer sandwiched between two steel sheets, offering excellent thermal and acoustic insulation.
- Applications: Used in cold storage, warehouses, and buildings requiring temperature control.
