What are the different shapes and sizes of aluminum profiles commonly used in construction?

Aluminum profiles used in construction come in various shapes and sizes to cater to different structural needs. Common shapes include angles, channels, I-beams, H-beams, T-profiles, and rectangular or square tubes. Sizes vary based on the thickness of the aluminum and the dimensions of the profile, such as width, height, and length. For instance, an H-beam might have a depth ranging from 100mm to 900mm and a width from 50mm to 300mm. The selection of the right profile depends on the specific requirements of the construction project, such as load-bearing capacity, aesthetic considerations, and cost efficiency.
