| ALUMINUM |
- ALUMINUM Specification
- ALUMINUM CHANNEL is officially classified in three categories
- When structural shapes were first produced in aluminum they were “rolled” similar to steel structural shapes and were thus also designed similar to them: these are “AMERICAN STANDARD”. With the development of the “extrusion” process it became evident that the “AMERICAN STANDARD” profiles do not utilize the metal efficiently so the “ALUMINUM ASSOCIATION” developed new sizes. These new sizes have better structural stability and the flanges match up better to beams of the same height.
