To prevent damage to your aluminum sheets during installation, follow these steps: Use protective gloves to avoid scratches from hand contact. Handle the sheets with care, especially at the edges and corners. Keep the surface clean and dry to prevent any dirt or moisture that could cause damage. Use appropriate tools designed for aluminum to avoid marring the surface. Ensure the installation site is free from debris that could cause scratches or dents. Install the sheets in a controlled environment to avoid exposure to harsh weather conditions. Finally, consider using a protective film or cover on the aluminum sheets until they are fully installed.
