How to maintain and repair aluminum sheets after installation?

To maintain and repair aluminum sheets after installation, follow these steps: Regularly clean the surface with a soft cloth and mild detergent to remove dirt and grime. Avoid abrasive materials that can scratch the surface. For minor scratches or dents, use aluminum filler or touch-up paint that matches the sheet's color. Apply the filler or paint carefully, following the manufacturer's instructions. For more severe damage, consider hiring a professional to assess and repair the damage to ensure structural integrity. Always check for any signs of corrosion and address them promptly to prevent further damage. Regular maintenance will prolong the life of aluminum sheets and keep them looking their best.
