With the increasing popularity of composite decking, homeowners are exploring alternative options for the framework beneath their deck surfaces. Traditional pressure-treated wood framing is currently under evaluation in contrast to its steel alternative. Deciding on the optimal material for your deck requires a closer look at crucial factors. Come along as we examine the considerations between wood and steel framing.

Durability

The lifespan of your deck hinges significantly on the resilience of its supporting framework. As composite decking gains popularity, homeowners frequently encounter issues with the deterioration of their frames preceding that of the deck surface. This underscores the significance of a robust frame, such as steel framing.

Renowned for its remarkable durability, steel surpasses both wooden frames and composite decking in longevity. In contrast to wood, steel remains impervious to warping, rot, or cracking. While wooden frames typically endure for 10 to 40 years, depending on wood quality and maintenance, steel frames can effortlessly extend beyond 25-50 years, requiring no maintenance whatsoever.

Maintenance

Maintenance becomes a crucial consideration, particularly when dealing with wood framing. There are additional concerns to bear in mind, as it can become a breeding ground for insects or mold, leading to potential damage over time. Wood is also susceptible to rot, especially in damp or humid conditions. Consequently, regular inspections are even more critical to detect potential issues early.

Addressing any identified issues promptly is essential. Remediation may range from a straightforward treatment with a cleaning product to more intricate procedures, such as engaging a pest control company. These potential problems not only require your time but can also contribute to additional expenses within your deck maintenance budget.

Insect Resistance

Wood is vulnerable to termites, carpenter bees, and other wood-eating insects. While pressure-treated wood can offer some protection against this issue, it's not entirely foolproof.

On the flip side, steel, being a non-organic material, is resistant to insects. Opting for steel framing, like with composite decking, ensures you won't need to concern yourself with termite damage or issues related to insects.

Fire Resistance

The fire rating holds significant importance for safety considerations. Typically, most wood types are assigned a class C fire rating, indicating a moderate resistance to fire.

In contrast, steel does not combust. With a class-A fire rating, the highest attainable rating, steel provides unparalleled fire protection.

Visual Appeal

Wood, with its textured grain and inherent charm, can introduce a unique character to your outdoor area. Yet, it's important to acknowledge that the allure of wood framing diminishes relatively quickly over time. Within 10-15 years, discoloration and evident signs of wear will become noticeable.

Conversely, steel maintains its color and form, maintaining a fresh and new appearance for decades after installation. Often in a sleek black hue, it contributes a modern and high-quality aesthetic to any deck.

Financial Considerations

Budget plays a crucial role in the decision between wood and steel framing for your deck. Generally, wood comes with a more affordable upfront cost compared to steel. This makes wood a favorable option if you are working within budget constraints, allowing you to create a larger deck without exceeding your financial limits.

However, the financial landscape shifts when considering the long term. Wood framing demands more maintenance and potential repairs, leading to increased costs over time.

In contrast, despite its higher initial cost, steel offers durability and minimal maintenance, proving to be a cost-effective choice in the long run. If your deck surface ages faster than the steel frame, a resurfacing job—considerably cheaper than a full replacement—will suffice.

Depending on the specific products and your contractor, constructing a deck with a steel frame may cost approximately 20-30% more than one built with a wooden frame.

Choosing Between Wood and Steel Framing: Final Thoughts

Deciding between a wood and steel deck involves considering various factors. Steel, with its exceptional durability and minimal maintenance requirements, can prove to be a wise investment despite its higher initial cost. On the other hand, wood, with its lower upfront cost, may be an attractive option for those on a tighter budget or those who appreciate its natural appeal.
