Tips for Maintenance and Care of Aluminum Corner Extrusions

Aluminum corner extrusions are widely used in various industries, including construction, automotive, and furniture manufacturing. They offer excellent strength, durability, and resistance to corrosion, making them ideal for applications where structural integrity and aesthetics are essential. To ensure the longevity and optimal performance of aluminum corner extrusions, proper maintenance and care are crucial.

Cleaning and Surface Protection

Regular Cleaning: Regularly clean the extrusions using a mild detergent and water solution. Avoid using harsh chemicals or abrasive cleaners that can damage the surface.

Protective Coating: Apply a protective coating to the extrusions after cleaning to prevent oxidation and corrosion. This coating will form a barrier between the aluminum surface and the environment, reducing the likelihood of tarnishing or discoloration.

Inspection and Repairs

Regular Inspection: Regularly inspect the extrusions for any signs of damage, such as scratches, dents, or cracks. Early detection of damage will allow for prompt repairs, preventing further deterioration.

Repair of Minor Damage: Minor damage, such as scratches or dents, can be repaired using a soft cloth and a metal polish. For more severe damage, professional repair is recommended.

Storage and Handling

Proper Storage: Store aluminum corner extrusions in a dry, cool, and well-ventilated area. Avoid exposing them to excessive moisture or direct sunlight, as these can cause corrosion or discoloration.

Careful Handling: Always handle the extrusions with care to avoid scratching or denting the surface. Use proper lifting equipment and wear gloves when handling heavy extrusions.

Maintenance in Specific Applications

Construction: In construction applications, aluminum corner extrusions are often exposed to harsh weather conditions. Regular cleaning and inspection are essential to ensure their durability. Proper flashing and sealant should be used to prevent water infiltration and corrosion.

Automotive: Aluminum corner extrusions used in automotive applications face exposure to road salt and chemicals. Regular washing and waxing will help protect the surface from damage.

Furniture: Aluminum corner extrusions in furniture can be cleaned using a mild detergent and water solution. Avoid using harsh chemicals or abrasive cleaners that can damage the finish.


Proper maintenance and care of aluminum corner extrusions are essential to ensure their longevity and optimal performance. By following these tips, you can prolong the lifespan of the extrusions, maintain their aesthetics, and minimize the need for costly repairs or replacements. Regular cleaning, surface protection, inspection, repairs, and proper storage and handling practices will help you keep your aluminum corner extrusions looking and performing their best for years to come.
