Columbarium units are typically constructed from three primary materials: pure aluminum alloy, galvanized steel, and aluminum composite panels. In this article, Sales Manager Mr. Luo from Jiangxi HuaHeng Columbarium Factory will explain the benefits of each material.

What Are the Advantages of Pure Aluminum Alloy?
Excellent Processability
By adding specific alloying elements, aluminum achieves superior castability, making it highly adaptable for manufacturing.

Strong Corrosion Resistance
Aluminum naturally forms a dense, protective oxide film on its surface, effectively shielding the material from corrosion.

High Plasticity
It can be easily shaped into various profiles and offers excellent electrical and thermal conductivity, as well as corrosion resistance—second only to silver, copper, and gold.

High Strength
Its strength is comparable to or even exceeds that of high-quality steel. Cold working can enhance its strength, and some aluminum alloys can be further strengthened through heat treatment.

Low Density
The density of aluminum and its alloys is approximately 2.7 g/cm³, about one-third that of iron or copper.

What Are the Advantages of Galvanized Steel?
High Toughness
The zinc coating forms a unique metallurgical structure that offers robust protection against mechanical damage during handling and use.

Long-Lasting Durability
In suburban environments, standard galvanized coatings can last over 50 years without requiring maintenance.

Superior Reliability
The zinc coating is metallurgically bonded to the steel substrate, making it an integral part of the surface and ensuring long-term durability.

Corrosion Resistance
Galvanized steel performs well in various environments and offers extended anti-corrosion protection, though actual longevity depends on specific conditions.

Time and Labor Efficiency
The galvanization process is faster than other coating methods and eliminates the need for on-site painting after installation.

What Are the Advantages of Aluminum Composite Panels?
Light Weight
Composed of aluminum layers and a low-density plastic core, these panels are lighter than aluminum sheets of the same rigidity or thickness.

High Rigidity
The structure follows the I-beam principle, providing unique mechanical properties. As the panel cools after forming, differences in shrinkage rates between the aluminum layers and the core create internal stress, resulting in high rigidity and resistance to deformation.

Strong Decorative Appeal
The surface can be customized in a wide range of colors and patterns. Advanced printing technology can mimic the appearance of granite, wood, or metal, offering high-quality visual effects that blend well with various architectural styles—ideal for modern Columbarium design.

The above overview by Mr. Luo highlights the distinct advantages of each material. At HuaHeng Columbarium Factory, we select the most suitable material based on specific requirements to ensure the durability and aesthetic quality of our Columbarium products. Each Columbarium niche is carefully crafted to offer both functionality and visual harmony.
