The lifespan of non-galvanized nails in treated lumber is a cause for concern. While the rate of corrosion may be slower in dry applications, pressure-treated lumber will still cause corrosion over time. The chemicals in the treated lumber can corrode non-galvanized nails, and the moisture in the air can also contribute to the corrosion process. While the floor won't be flying off into orbit, as one Reddit user quipped, it is still important to address the issue. Standard steel nails will rust and corrode when exposed to moisture, and the chemicals in pressure-treated lumber can accelerate this process. While there are no definitive timelines for how long non-galvanized nails will last in treated lumber, estimates range from a few years to over a decade.

What You'll Learn
Non-galvanized nails will corrode in treated lumber
Galvanized nails are coated in zinc, which helps to protect the nail from corrosion and improves its durability. This coating allows galvanized nails to withstand exposure to moisture and other elements that could cause rust or structural failure. The zinc coating also helps to prevent staining or discoloration of the treated wood.
The lifespan of galvanized nails in pressure-treated lumber can vary depending on several factors, including the quality of the nails and the environment. In some cases, galvanized nails can last over 85 years, while in others, they may show signs of corrosion after just three years. For projects in highly corrosive environments, such as near the ocean, stainless steel fasteners are recommended.
While non-galvanized nails will eventually corrode in treated lumber, the failure of the nails may take several years. In the short term, the worst-case scenario is that the floor may start to squeak or lift, which can be fixed by driving stainless steel screws to secure it in place.
To prevent corrosion and ensure the longevity of your project, it is recommended to use galvanized nails or fasteners specifically designed for use with treated lumber.

The rate of corrosion depends on moisture exposure
The rate at which non-galvanized nails corrode depends on their exposure to moisture. Non-galvanized nails are standard steel nails that will rust and corrode when exposed to moisture. While pressure-treated lumber is resistant to rot and insects, it contains chemicals that can cause corrosion in non-galvanized nails.
The level of corrosion will depend on the amount of moisture the nails are exposed to. If the lumber is kept completely dry, corrosion will still occur but to a minimal extent. However, if the nails are exposed to moisture, either from the environment or the chemicals in the pressure-treated lumber, the rate of corrosion will increase significantly. In wet conditions, iron nails will rust quickly, weakening the structure and reducing its lifespan.
The presence of moisture, especially in damp climates, can accelerate corrosion. This is a crucial consideration for outdoor projects, where exposure to rain and humidity is inevitable. Additionally, the chemicals in pressure-treated lumber can also contribute to corrosion, even if the nails are not directly exposed to external moisture.
The rate of corrosion can vary depending on the specific environment and the treatment of the lumber. For example, in highly corrosive environments near the ocean, stainless steel fasteners are recommended. Additionally, factors such as acid rain can further exacerbate the corrosion problem.
To mitigate the effects of moisture exposure and corrosion, galvanized nails are recommended. The galvanization process involves coating the metal with a layer of zinc, which protects the nail from corrosion and extends its durability. Galvanized nails can withstand exposure to moisture and are specifically designed for use with pressure-treated lumber, making them a cost-effective and long-lasting option.

Galvanized nails are coated in zinc to prevent rust
Non-galvanized nails will last in treated lumber for as long as any galvanized nail. However, standard steel nails will rust and corrode when exposed to moisture, be it from exterior elements or the chemicals in pressure-treated lumber.
Galvanized nails, on the other hand, are coated in zinc to prevent rust and corrosion. The galvanization process involves coating the metal with a layer of zinc, which helps to protect the nail from corrosion and improves its durability. This allows galvanized nails to withstand exposure to moisture and other elements that could cause rust or structural failure.
There are two main types of galvanized nails: Hot-Dip Galvanized (HDG) and Electro-Galvanized (EG). The former involves cleaning the steel body, submerging the nail into molten zinc, and spinning it to remove excess coating. The latter involves using an electric current to charge the zinc acid and attach it to the nail's body. HDG nails offer the highest quality of galvanization, with a minimum zinc coating thickness of 1.7 mils, evenly covering all nail surfaces from head to tip. EG nails, while suitable for indoor applications, have a thinner coating of 0.36 mils maximum and a typical coating lifetime of 5-10 years.
Despite the benefits of galvanized nails, it is important to note that they are not entirely rust-proof. Over time, the zinc coating may corrode, exposing the underlying steel. However, galvanized nails often develop a form of corrosion called white rust, which appears as a powdery, whitish substance on the surface. If detected early, proper maintenance and remedial measures can prevent further deterioration.
To maximize the lifespan of galvanized nails, several measures can be taken, including regular inspections, prompt replacement of damaged or worn-out nails, avoiding exposure to corrosive substances, and applying additional protective coatings such as epoxy or paint.

Stainless steel is a more expensive but longer-lasting option
When it comes to choosing the right type of nails for your project, there are a few options to consider. While non-galvanized nails are an option, they may not be the best choice for long-term durability, especially when used with treated lumber. Standard steel nails, for instance, are susceptible to rust and corrosion when exposed to moisture, which can lead to structural failure.
Galvanized nails are a popular choice for treated lumber as they undergo a process called galvanization, where a layer of zinc is coated onto the metal, protecting it from corrosion and extending its durability. This coating helps galvanized nails withstand moisture and other elements that could cause rust. However, the effectiveness of galvanization can vary, and lower-quality galvanized nails may still rust and stain the wood over time.
Now, if you're looking for a more durable and corrosion-resistant option, stainless steel nails are the way to go. Stainless steel is highly resistant to corrosion and will completely prevent rust, ensuring your project's longevity. This is especially beneficial when working with certain types of wood, such as cedar or redwood, which can react with the zinc coating on galvanized nails and cause streaking and discolouration.
While stainless steel nails are more expensive than galvanized nails, they offer superior protection against corrosion and rust. For outdoor projects or those in moisture-prone areas, the added cost of stainless steel nails may be well worth it to avoid the hassle of replacing corroded nails and maintaining the structure's integrity.
Additionally, stainless steel nails can save you from potential callbacks or repairs due to rusted nails, which could end up costing more in the long run. By investing in stainless steel nails, you can have peace of mind knowing that your project will remain sturdy and aesthetically pleasing for years to come.

Coated outdoor screws are another alternative to nails
While galvanized nails are a great option for outdoor projects, they are not the only option. Coated outdoor screws are another alternative to nails and are ideal for pressure-treated wood and outdoor decking. They are designed to resist the chemicals in pressure-treated wood, as well as the tannin or tannic acid found naturally in cedar, and will not cause staining or corrosion.
There are a few different types of coated outdoor screws available. One option is to use screws that are coated with an epoxy-based polymer resin. These screws are often called "deck screws" and are made from corrosion-resistant materials like stainless steel or coated with epoxy. They are used for wood-to-wood fastening and have a sharp point, a coarse thread, and a partly unthreaded shank near the head. Deck screws are budget-friendly and come in a variety of head shapes, lengths, and diameters.
Another type of coated outdoor screw is the ceramic screw. These screws have a thin epoxy or ceramic coating that gives them greater resistance to rust than uncoated fasteners. They are also budget-friendly and come in a variety of designs for general exterior use. Ceramic screws can be used with a jig to drill angled pocket holes and form strong joints.
Additionally, stainless steel screws are another great option for outdoor use. There are two common types of stainless steel fasteners: stainless steel 304 and stainless steel 316. Stainless steel 304 fasteners are made from a combination of nickel and chromium, making them highly rust-resistant. They are perfect for drier climates and timber cladding and decking applications. On the other hand, stainless steel 316 fasteners, also known as "marine-grade fasteners," are recommended for humid climates and coastal areas. They are made from nickel, chromium, and molybdenum, which resist corroding and pitting from chlorides.
Coated outdoor screws may be more time-consuming to install than nails, but they can provide a more effective and long-lasting result. They are specifically designed to resist corrosion and staining, which can compromise the integrity of a structure.
