Today, “sustainability” is so much more than a buzzword among the next generation of homeowners. A 2024 third-party study found that 73% of Gen Zs and 77% of Millennials take tangible steps to minimize their impact on the environment. This action-oriented mindset extends to the building products they use when upgrading their outdoor living spaces… from the railing that encloses their deck to the type of fencing that demarcates their property line.

So, what is the most environmentally friendly fencing? A wood-alternative option, steel fencing is a sustainable choice that tops treated wood fencing. Plus, thanks to its premium performance qualities and visual appeal, a steel fence makes it possible for homeowners to make an environmentally responsible purchase without compromising on their vision for their backyard.

Steel fencing made from recycled and recyclable materials

A product that is made from recycled materials and similarly, can be recycled at the end of its service life, is going to score high marks on its “sustainability factor.” This is where pressure-treated wood fencing falls short. For example, a 100-foot-long cedar fence built at 6 feet high will consume about 10 mature trees. It may take a combined 600 years to grow those 10 trees back. Take a minute to reflect on the impact of that choice.

An eco-friendly option, steel is one of the most recycled materials on the planet. Made from recycled content, steel fences contribute to the circular economy: a model in which products and materials are kept in circulation as long as possible and then recycled and reused to create new goods. The process repeats over and over again. This means that after its long service life, steel fencing can contribute to the circular economy logic.

Steel fences are resilient and built to last

Speaking of… a product's service life is another key factor to consider when it comes to determining the most environmentally friendly fencing. A fence that deteriorates quickly ends up costing more in upkeep (will need to regularly purchase stain and sealant), materials (replacement boards and eventually a new fence), and environmental impact.

Because wood is susceptible to the damaging effects of weathering, it is not uncommon to see wooden fences starting to look rough (think warping, rotting and deterioration) after just a few years of exposure to the elements. Even with regular maintenance, most traditional wood fences need to be replaced every 10 years or so.

But fencing that leverages the tried-and-true performance of steel is going to stand strong year after year. Incredibly durable, a steel fence won't succumb to warping, rotting or deterioration after long-term exposure to the weather like a wood fence will. Tough and built to last, steel fences purchased from an industry-leading manufacturer are also going to be backed by a strong warranty, which should give the homeowner peace of mind in the integrity of their purchase.

Protecting the natural ecosystems in the backyards with steel fencing

Keep in mind that treated wood fencing uses toxic preservatives to help prevent rotting caused by moisture absorption and insects. The harmful chemicals that are used can end up in groundwater, harming the local ecosystem. Plus, treated wood can no longer be recycled and reused. Instead, it typically ends up in a landfill.  

High-quality steel fencing, on the other hand, does not require the use of treatment chemicals to deliver enhanced weatherability. And when it comes to expectations around upkeep, homeowners won't need anything but soap and water. Talk about low maintenance. Most importantly, this fencing choice helps environmentally conscious homeowners keep toxic chemicals out of their backyard and the local water supply.

Steel is an environmentally friendly fencing choice

Thanks to its many sustainable qualities, steel fencing tops old-school treated wood fencing as the most environmentally friendly fencing option.
