Temper (Condition)
| Temper | Description |
|---|---|

For most metal aluminium diamond plate sheets 4×8, 3003-H14 is a common choice.
Types of Alloys and Tempers
The strength and flexibility of the sheet depend on the alloy used. Most suppliers offer two main grades.
1. Alloy 3003-H22 aluminum sheet

This is the most common alloy for cosmetic and light-duty use. It is easy to bend and has a very bright, shiny finish. You will often see this on truck toolboxes and wall accents.
2. Alloy 6061-T6 aluminum sheet

This is a structural grade. It is much stronger than 3003. It is used for loading docks, stairs, and heavy-duty flooring and harder to bend but can support much more weight.
