Steel vs. Wood: Why Steel Wins in Construction Projects

Apr 23, 2024 | Construction Materials

For many construction projects, the choice between steel and wood comes down to tradition versus innovation. While wood has long been a popular material, steel offers several advantages that make it a superior choice for fences, decks, and sheds in the long run.

At Metal World, we are obviously a little bit biased when it comes to which is better, since we work predominantly with steel, but to help you make the best decision for your project, we’re going to look at the key differences between these two materials.

Strength and Durability

Strength and durability are both incredibly important factors because they will determine the integrity of the structure being built.

  • Wood: Prone to warping, cracking, and rotting due to moisture exposure. Susceptible to termite and insect damage. Strength diminishes over time, requiring repairs or replacements more frequently. Wood fences may struggle to support climbing vines or heavy privacy screens.
  • Steel: Impervious to moisture and pests. Significantly stronger than wood, allowing for larger spans and greater weight capacity. Steel framing for decks can accommodate heavier furniture and hot tubs compared to wood. Steel sheds can withstand strong winds and harsh weather conditions without sustaining damage. Maintains its structural integrity for decades, reducing the need for replacements and repairs.

Longevity and Maintenance

The next factors are also important, because they will affect the cost of your choice, in the long term.

  • Wood: Requires regular staining, sealing, or painting to maintain its appearance and prevent rot. This can be a time-consuming and ongoing chore. Wooden components, especially those exposed to the elements, may need to be replaced periodically due to wear and tear. This adds to the overall cost of ownership throughout the life of the structure.
  • Steel: Minimal maintenance required. An occasional cleaning with soap and water is sufficient to remove dirt and grime. Steel’s strength ensures it will last for the lifetime of the structure, eliminating the need for constant upkeep and saving you time and money in the long run.

Safety and Fire Resistance

This comparison is a natural consideration, as you will want to make sure that you opt for a material that will offer maximum safety.

  • Wood: Highly flammable, posing a significant fire hazard. Embers from a nearby fire can easily ignite a wooden fence, deck, or shed. Treated wood may contain chemicals that raise safety concerns, especially if the wood burns.
  • Steel: Non-combustible, providing superior fire resistance for added safety. This is a crucial factor to consider, especially in areas prone to wildfires. Steel fencing creates a fire barrier that can help protect your property from flames spreading from neighbouring areas. Steel sheds offer a secure fireproof storage solution for valuable possessions.

Environmental Impact

While this won’t affect the quality of the material, whether or not it is eco friendly is something that some companies like to know.

  • Wood: Requires harvesting trees, a finite resource. Deforestation for lumber production can have a negative impact on ecosystems. Treatment chemicals used on wood can leach into the soil and contaminate groundwater.
  • Steel: Made from recycled materials in large part. The steel industry has made significant strides in sustainability, with a high percentage of steel products containing recycled content. Steel is also highly recyclable at the end of its lifespan, minimising waste. By choosing steel, you’re contributing to a more sustainable building process.

Design Flexibility and Aesthetics

When building a home or a structure that will be seen regularly by others, you can to consider the aesthetics.

  • Wood: Offers a traditional aesthetic that complements some architectural styles. However, customisation options are limited, especially for fences and sheds. The natural look of wood may fade and weather over time.
  • Steel: Available in various colors and finishes to suit modern and contemporary design preferences. Powder-coated steel can mimic the look of wood with a more durable finish. Steel can be incorporated into sleek and stylish structures that complement a variety of architectural styles. For fences and decks, steel allows for more intricate designs and patterns compared to traditional wood construction.

Construction Considerations

Finally, you need to know which is easier to work with.

  • Wood: Generally requires more on-site construction and assembly, potentially leading to longer project timelines and higher labor costs. Cutting, treating, and staining wood can be a time-consuming process. Improper installation of wooden structures can compromise their strength and durability.
  • Steel: Many steel components are prefabricated in controlled environments, ensuring consistent quality and precise measurements. This allows for faster and easier assembly on-site, saving time and labor costs. Prefabricated steel structures are also less susceptible to installation errors compared to complex wooden frameworks.

The Verdict

While wood may have a certain rustic charm, steel’s superior strength, durability, and low-maintenance requirements make it the smarter choice for most construction projects. Steel structures offer lasting value, fire safety, design flexibility, and a minimised environmental impact. So next time you’re planning a fence, deck, or shed, consider the advantages of steel for a project that will stand the test of time and enhance the beauty and functionality of your property.
