Conditions that are conducive to attack by fungal decay and termites also promote metal corrosion. Therefore, fasteners should be corrosion-resistant, such as:
| • hot-dipped galvanized | |
| • copper | |
| • silicon bronze | |
| • stainless steel 304 and 316 | |
| • other metals having corrosion resistance equal to that of hot-dipped galvanized |
Aluminum is subject to corrosion and should not be used in direct contact with CCA-treated wood.
