To avoid warping or twisting of aluminum profiles during installation, ensure proper handling and support. Use sturdy brackets and supports to maintain alignment and prevent bending. Keep the profiles clean and free of debris that could cause uneven pressure. Avoid overtightening fasteners, which can cause stress and deformation. Use the correct tools and techniques for cutting and drilling to avoid damage. Maintain a consistent temperature and humidity during the installation process, as extreme conditions can affect the material's stability. Finally, inspect the profiles regularly for any signs of warping or twisting and address issues promptly.
