How Long Do Metal Pergolas Last?

An outdoor pergola is the perfect way to transform your garden into an outdoor oasis. And while you can’t go wrong with a wood pergola, metal has become a strong and durable alternative.

Metal pergolas provide an elegant and stylish complement to any property, particularly those with a modern aesthetic. And when properly treated by the manufacturer, metal pergolas should last for decades, making them excellent value for money.

Most homeowners looking to purchase a metal pergola decide on either aluminium or galvanised steel. While both materials are pleasing to the eye, their different properties have a huge impact on the durability and longevity of your pergola. To ensure you can enjoy yours for as long as possible, here are some of the key differences between an aluminium and galvanised-steel pergola.

Strength and Stability

Some people favour aluminium pergolas for their lower price and lighter weight. Unfortunately, these qualities come at the cost of strength and stability, which in turn makes aluminium pergolas less resistant to heavy wind. 

Galvanised-steel, on the other hand, is a much stronger material. This gives your pergola significantly higher weatherproofing and allows you to leave it up all year round in any climate. 

To give your pergola the longest possible lifespan, we test and certify our products against wind and rain damage to bring you the ultimate in stability and durability. Our PRO-TECT™ Tested and Proven provides peace of mind that your pergola can withstand winds up to 100 mph when properly anchored. 

Rust and Corrosion

Those who favour aluminium pergolas often claim that aluminium doesn’t rust, whereas steel does. That’s not exactly true.

The galvanised steel we use is coated with a thin layer of zinc that stops water and oxygen from reaching the underlying metal. That makes it extremely resistant to rust and corrosion. On top of that, Backyard Discovery steel pergolas are powder-coated to provide additional protection and extend their maximum lifespan.

In general, neither aluminium nor steel pergolas require much maintenance, making them very easy to care for. All you need to do is wash the frame on a regular basis to remove debris. Backyard Discovery pergolas take this a step further.

We’ve designed our galvanised steel pergolas to be completely maintenance-free. That means you don’t need to re-stain or reseal them at any point, no matter where, when or how often you use it. And as well as offering superior rust resistance, our powder coating prevents chipping, scratching and UV harm for total protection and convenience.
