When it comes to exterior trim, it is important to select the right type of nails to ensure longevity. While galvanized finish nails are commonly used for outdoor projects, there are different types of galvanization to consider. Electroplated galvanized nails have a very thin layer of zinc that can be easily scratched, exposing the steel underneath to the elements and leading to oxidation. In contrast, hot-dipped galvanized nails have a much thicker zinc coating that provides better protection against corrosion. However, hot-dipped galvanized nails may not be suitable for all applications due to their rough surface and potential for nails to stick together. For exterior trim, it is crucial to avoid nails that will rust or react with the wood, and stainless steel nails are often recommended for their superior resistance to rust and corrosion.

What You'll Learn
Hot-dipped galvanised nails are better for exterior use
When it comes to exterior trim, hot-dipped galvanised nails are the preferred choice for their durability and resistance to the elements. Galvanised nails are coated in zinc, which helps to slow down the process of rusting and corrosion, thereby prolonging the nail's lifespan compared to non-coated alternatives.
Hot-dipped galvanised nails, in particular, offer a superior level of protection due to their thicker zinc coating. This is achieved by dipping the nails into molten zinc, resulting in a minimum thickness of 1.7 mils of zinc evenly covering all surfaces from head to tip. The process also involves cleaning the steel body and spinning the nail to remove excess coating. This ensures that the nails are well-protected and can withstand exposure to outdoor conditions.
In contrast, electroplated galvanised nails have a much thinner coating that is easily scratched or breached. A hammer striking the head of such a nail could expose the underlying steel to the elements, leading to oxidation and rust. While hot-dipped galvanised nails may have a rougher surface or bumps from the zinc coating, this does not compromise their functionality.
Hot-dipped galvanised nails are also cost-effective, striking a good balance between cost and quality. They are readily available at local building materials stores and offer a lifespan of 30-50+ years. For these reasons, hot-dipped galvanised nails are recommended for exterior use, ensuring the durability and longevity of outdoor projects.

Electroplated galvanised nails are not suitable for exterior use
While galvanised nails are commonly used for exterior applications, electroplated galvanised nails are not suitable for exterior use. This is because the electroplating process results in a very thin layer of zinc coating, which can easily be scratched or breached. Once the zinc coating is scratched or breached, the underlying steel is exposed to moisture and air, and will begin to rust and corrode.
Galvanised nails with a thicker zinc coating, such as Hot-Dip Galvanised (HDG) nails, are more suitable for exterior use as they provide better protection against rust and corrosion. HDG nails are created by dipping the nail in liquid metal, resulting in a rougher surface but a more durable coating. While they may be more challenging to work with due to their rough texture, HDG nails are a better choice for exterior trim as they will protect the underlying material from the elements.
It is worth noting that some sources suggest that electroplated galvanised nails can be used for exterior applications, such as roofing, and that they have a long lifespan of around 25 years. However, the packaging for these nails often indicates that they are for "interior use only" or should not be used "where surface rust is unacceptable". As such, it is recommended to opt for HDG nails or stainless steel nails for exterior trim to ensure a longer-lasting and higher-quality finish.
The main goal when choosing nails for exterior trim is to select fasteners that will not rust or react with the wood. While electroplated galvanised nails offer some protection against rust and corrosion, their thin coating makes them less suitable for exterior use compared to other options on the market. Therefore, it is advisable to choose HDG or stainless steel nails for exterior applications to ensure the best results and maintain the integrity of the structure.
In summary, while galvanised nails are commonly used for exterior projects, electroplated galvanised nails are not the best choice due to their thin zinc coating, which can easily be breached, exposing the nail to the elements. For exterior trim, it is recommended to opt for fasteners with thicker zinc coatings, such as HDG or stainless steel nails, to ensure a durable and long-lasting finish.

Stainless steel nails are more expensive but more resistant to rust
When it comes to exterior trim, the use of galvanized finish nails is a common topic of discussion. While galvanized nails are often used for outdoor projects, there are specific types that are more suitable for exterior use. Regular bright electro-galvanized nails, for instance, are typically intended for interior use only. This is because electroplated nails have a very thin layer of zinc protection, which can be easily scratched or breached during hammering, exposing the steel to the elements and leading to oxidation and rust.
Hot-dipped galvanized (HDG) nails, on the other hand, are considered suitable for exterior use. HDG nails have a much thicker zinc coating applied through a dipping process, making them more resistant to rust. However, they may result in a rough surface and the nails may sometimes stick together due to the zinc coating.
While HDG nails offer improved protection against rust, stainless steel nails take it a step further. Stainless steel nails are even more resistant to rust, making them ideal for exterior applications where rust protection is a priority. This added benefit comes at a cost, as stainless steel nails are generally more expensive than their galvanized counterparts.
The choice between HDG and stainless steel nails depends on the specific requirements of the project and the budget. If you're working on a coastal project or in a salt environment, the superior rust resistance of stainless steel nails may be well worth the extra cost. In such corrosive environments, even 304 stainless steel can suffer from corrosion, so opting for 316 stainless steel nails is recommended.
For projects where the risk of corrosion is lower or budget constraints are a factor, HDG nails can be a more economical choice while still providing adequate protection against rust for exterior trim applications.

Galvanised nails are not suitable for certain types of wood
While galvanised nails are suitable for exterior use, they are not suitable for certain types of wood. For example, galvanised nails should not be used with cedar, redwood, or treated lumber. If they are going to be used in pine, they should be countersunk and the heads should be caulked over.
The galvanisation process involves applying a protective zinc coating to the nail. When galvanised nails are electroplated, the plating material is very thin and can easily be scratched through. This means that when a hammer strikes the head of the nail, the zinc can be breached, exposing the steel to the elements and causing it to oxidise and rust.
Hot-dip galvanised nails, on the other hand, have a much thicker zinc coating applied by dipping the nail in liquid metal. These nails are suitable for exterior use and can be found at most local building materials stores. However, they may result in a rough surface and bumps of zinc on the nail.
For certain types of wood, such as cedar, redwood, and pressure-treated wood, stainless steel nails are recommended. Stainless steel nails are more resistant to rust and corrosion than galvanised nails, although they are more expensive.
In summary, while galvanised nails are suitable for exterior use, they should not be used with certain types of wood, such as cedar, redwood, or treated lumber. Hot-dip galvanised nails are a better option than electroplated galvanised nails for exterior use, but stainless steel nails are the most resistant to rust and corrosion.

Galvanised nails are not suitable for treated lumber
Galvanised finish nails are not always suitable for exterior use. While galvanisation adds a zinc coating to nails that protects them from corrosion, standard electro-galvanised nails are not recommended for exterior use. This is because the zinc coating is very thin and can easily be scratched, exposing the steel underneath to the elements and causing it to oxidise.
Hot-dipped galvanised nails, on the other hand, are suitable for exterior use. The hot-dipping process results in a thicker zinc coating that provides better protection against corrosion. However, hot-dipped galvanised nails are not suitable for all types of exterior applications.
When it comes to treated lumber, galvanised nails, in general, are not recommended. Treated lumber, such as pressure-treated wood, contains chemicals that can react with the nails and cause corrosion. This is especially true for standard steel nails, which will quickly rust and corrode when exposed to the chemicals in treated lumber.
To avoid these issues, it is recommended to use fasteners that are specifically designed for use with treated lumber. These fasteners are made from materials that can withstand the chemicals and moisture present in treated wood, preventing rust and structural failure. For example, stainless steel nails are more resistant to rust and are a better option for exterior trim. Additionally, ring shank nails are great for treated lumber as they have a textured edge that helps them grip firmly into the wood.
In conclusion, while galvanised nails can provide some protection against corrosion, they are not always suitable for exterior applications, especially when it comes to treated lumber. It is important to consider the specific type of galvanised nail and the environment in which it will be used to ensure the best results and avoid potential issues.
