Aluminum sheet profiles come in a variety of types, suitable for different applications. Some common types include: 1. Flat Sheets: These are simple, flat aluminum sheets with no bends or curves. 2. Corrugated Sheets: These have a wavy or ridged pattern, providing strength while allowing flexibility. 3. Perforated Sheets: These have holes punched in a regular pattern, useful for ventilation or decorative purposes. 4. Embossed Sheets: These have a raised pattern on the surface, often used for aesthetic or functional reasons. 5. Extruded Profiles: These are complex shapes created by pushing aluminum through a die, suitable for structural applications. 6. Expanded Metal Sheets: These have a diamond-shaped pattern, providing strength and rigidity. 7. Checkered Plates: These have a raised, non-slip pattern, often used for flooring. Each type has its own specific uses and properties, and the choice depends on the requirements of the project.
