1)  Anti-rust: Aluminum alloy material is not afraid of moisture and salt spray. After surface treatment such as anodizing, it will not rust for 20 years.

2)  Lightweight & Installed Easily: It is extremely light and does not require welding or large machinery for installation, making it especially suitable for construction at high altitudes or in remote areas.

3)  Water-permeable: The hollow grid can drain water quickly, thus preventing stagnant water from breeding mosquitoes and reducing the risk of diseases such as dengue fever, making it suitable for tropical areas.
