Aluminum profiles for flooring are designed to provide structural support and stability to the flooring system. Common types include: 1. T-profiles, which are used as support beams and can be easily connected to create a grid structure. 2. U-profiles, often used as edge trims or for creating a border around the flooring area. 3. H-profiles, which are suitable for heavy-duty applications and provide high load-bearing capabilities. 4. L-profiles, used for creating corners or edges in flooring systems. 5. C-profiles, which are used for covering or hiding the edges of the floor. Each type offers different benefits and is chosen based on the specific requirements of the flooring project, such as load capacity, aesthetic considerations, and ease of installation.
