Polished Aluminum Angles- A Comprehensive Buying Guide


Polished aluminum angles are a versatile and durable building material used in various applications, from construction and architecture to transportation and manufacturing. This comprehensive guide provides everything you need to know about polished aluminum angles, from their properties and benefits to their selection and installation.

Properties and Benefits of Polished Aluminum Angles

Excellent Corrosion Resistance: Aluminum’s natural oxide layer and the polishing process enhance its resistance to corrosion and oxidation, making it suitable for outdoor applications.

High Strength and Durability: Polished aluminum angles offer exceptional strength and rigidity, providing structural support and resisting deformation.

Lightweight: Aluminum is a lightweight material, reducing the overall weight of structures and making them easier to handle and install.

Reflective Surface: The polished finish creates a highly reflective surface that can reflect light and heat, reducing energy consumption and improving aesthetics.

Fire Resistance: Aluminum has a high melting point and does not support combustion, providing fire resistance and safety.

Key Considerations for Selecting Polished Aluminum Angles

Alloy Selection

The alloy composition determines the strength, corrosion resistance, and other properties of polished aluminum angles. Common alloys for polished angles include 6061, 6063, and 5052.

Temper Designation

The temper designation indicates the heat treatment process undergone by the aluminum angle. Different tempers offer varying degrees of strength and hardness. Common tempers for polished aluminum angles include T4, T5, and T6.


Polished aluminum angles are available in various dimensions, including width, thickness, and leg length. The appropriate dimensions will depend on the specific application requirements.

Surface Finish

The polishing process produces a smooth and glossy surface, enhancing the angle’s appearance and durability. Different polishing methods and grit sizes can achieve varying degrees of reflectivity.

Installation of Polished Aluminum Angles

Cutting: Use a saw or specialized cutting tool to cut the aluminum angle to the desired length.

Drilling: Drill holes for fasteners using a drill bit suitable for aluminum.

Fastening: Secure the polished aluminum angle to the structure using bolts, screws, or rivets.

Sealing: If necessary, apply a sealant around the fasteners to prevent water penetration.

Maintenance: Regularly clean and inspect the polished aluminum angle to maintain its appearance and integrity.


Polished aluminum angles are an ideal material for a wide range of applications due to their exceptional properties and durability. By carefully considering the alloy selection, temper designation, dimensions, surface finish, and installation methods, you can ensure the optimal performance and longevity of your polished aluminum angle project.
