Aluminum strips can be used for flooring in kitchens and bathrooms, but they are not the most common choice. They are known for their durability, resistance to moisture, and ease of cleaning, which are desirable traits for these areas. However, they can be slippery when wet, making them a less safe option for bathrooms. They also lack the warmth and comfort of other flooring materials, like tiles or wood. For kitchens, aluminum strips can be a good option for their low maintenance and resistance to spills, but they may not provide the aesthetic appeal that many homeowners desire. It's important to consider the specific needs and preferences of your space when choosing flooring materials.
