Does Aluminium U Channel Rust or Corrode?

Aluminium U Channel does not rust like ferrous metals such as iron or steel. Aluminium naturally forms a thin protective oxide layer when exposed to air, which helps protect the material from corrosion. Powder-coated or anodised aluminium can provide additional surface protection and improve durability, making it suitable for frameless glass balustrades used indoors and outdoors. However, aluminium can still experience corrosion under certain environmental conditions, particularly where it is exposed to aggressive chemicals, salt, or incompatible metals. Correct installation and suitable material selection help maximise its lifespan.

Is aluminium U channel suitable for outdoor glass balustrades?

Yes. Aluminium U Channel is commonly used for outdoor frameless glass balustrades because it is lightweight, durable, and naturally resistant to corrosion.

How do you maintain aluminium U channel?

Clean the channel regularly with water and a suitable mild detergent, remove dirt and debris, and inspect the channel and fixings for signs of damage or corrosion. Avoid abrasive cleaning products.
