What are the best practices for using treated lumber for decks to ensure durability and longevity?

To ensure durability and longevity when using treated lumber for decks, it is important to follow these best practices:

1. Use pressure-treated lumber that is rated for ground contact.
2. Properly seal and stain the lumber to protect it from moisture and UV damage.
3. Regularly inspect and maintain the deck, including checking for any signs of rot or decay.
4. Use stainless steel or galvanized hardware to prevent corrosion.
5. Avoid direct contact between treated lumber and certain materials, such as aluminum or copper, to prevent chemical reactions.
