What are the different types of aluminum profiles used for roof insulation systems?

Aluminum profiles for roof insulation systems are designed to provide structural support and thermal insulation. Common types include: 1) U-channels, which are used as support beams; 2) C-profiles, used for connecting and securing insulation boards; 3) H-profiles, serving as main rafters or purlins; 4) Z-profiles, often used as secondary rafters or for sealing; 5) T-profiles, used for creating airtight seals at the edges; and 6) L-profiles, which can be used for corner reinforcements. These profiles come in various sizes and thicknesses to suit different roofing specifications and insulation requirements.
