Corrosion Resistance and Service Life of Pre-insulated Aluminum Sheet

Compared with ordinary galvanized steel sheet insulation materials, aluminum alloy inherently possesses natural resistance to acids and alkalis, resistance to rain corrosion, and resistance to atmospheric oxidation. It is not prone to rust and corrosion even in humid environments or in areas with high salt spray from the sea.

The surface does not require regular painting maintenance. Its resistance to weathering and aging is outstanding, and under normal conditions, its service life can reach over 20 years.

In contrast, traditional iron sheet ducts are prone to rust and peeling, and need to be repaired and replaced within 3-5 years. In terms of overall comparison, the maintenance cost of pre-insulated aluminum plates is extremely low in the long term, and its overall cost-effectiveness is higher.

Market Advantages of Pre-insulated Aluminum Sheet

At present, building energy conservation and prefabricated buildings have become the mainstream in the industry. Prefabricated aluminum panels align with the modular and standardized construction trends, and have replaced the traditional duct insulation process as an industry trend.

They possess multiple functions such as structure, insulation, fire prevention, and corrosion resistance. The integrated design reduces the number of material layers and lowers the overall project cost. Whether for export or domestic project centralized procurement, they have strong market competitiveness and are the core preferred materials in the fields of HVAC insulation and building energy conservation.

The product is lightweight and easy to cut, bend and assemble. No additional insulation cotton or fiberglass cloth need to be wrapped. One-stop installation is achieved, significantly reducing the construction period and saving labor and auxiliary material costs.
