Columbarium units are typically made from three types of materials: pure aluminum alloy, galvanized sheet, and aluminum-plastic composite panel. Today, Sales Manager Mr. Luo from HuaHeng Columbarium Factory, Jiangxi, China will walk you through the features of each material.

What Are the Advantages of Pure Aluminum Alloy?

Excellent Workability
By adding specific alloying elements, aluminum can be given excellent casting properties, making it easy to mold and process.

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

Good Plasticity
It can be processed into various shapes 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 processing can further enhance its strength, and some grades can also be 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 Sheet?

High Toughness
The zinc coating forms a unique metallurgical structure that withstands mechanical damage during transportation and use.

Long-Lasting Durability
In suburban environments, standard galvanized anti-rust layers can last over 50 years without needing repair.

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

Strong Corrosion Resistance
Galvanized sheets are widely popular due to their adaptability to various environments and long anti-corrosion lifespan, though performance may vary depending on conditions.

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

What Are the Advantages of Aluminum-Plastic Panels?

Lightweight
Composed of aluminum and a low-density plastic core, aluminum-plastic panels are lighter than aluminum sheets of the same rigidity or thickness.

High Rigidity
These panels utilize the mechanical principles of I-beam structures, giving them unique mechanical properties. As the panel cools after forming, differences in shrinkage rates between the aluminum layers and the core create stable internal stress, resulting in high rigidity. Compared to single-layer aluminum sheets, they have a higher elastic limit, resist deformation, and maintain flatness over time under normal conditions.

Strong Decorative Appeal
The surface of aluminum-plastic panels can be customized in a variety of colors and patterns to suit different applications, including Columbarium design. Photographic reproduction technology can also imitate textures such as granite, wood grain, and metal, providing high-quality, detailed designs that solid colors cannot achieve. The wide range of colors and patterns allows the panels to harmonize with various architectural styles and environments, offering a visually pleasing experience.

The above is an introduction to Columbarium materials by Mr. Luo. Each material has its own advantages, and manufacturers at HuaHeng Columbarium Factory, Jiangxi, China should select the most suitable material based on specific requirements.
