Should Steel Deck Framing Be Pressure Treated

When it comes to building a deck, one of the most important decisions is deciding on the type of framing to use. While there are many options available, one question that often arises is whether or not steel deck framing should be pressure treated.

There are definitely benefits to using pressure treated steel deck framing. By treating the steel with preservatives, it becomes more resistant to rot, decay, and insect damage. This can extend the lifespan of the deck, which is especially important in areas with high humidity or frequent rainfall. Additionally, pressure treated steel is less likely to warp or twist over time, which can help keep the deck level and stable.

However, it's important to note that pressure treatment is not always necessary. If you live in a dry climate, or if your deck is elevated and not in direct contact with soil or plants, then untreated steel framing may be perfectly suitable. Furthermore, adding pressure treatment can increase the cost of your deck.
