How long do steel sheds last?


3 min read

There are many kinds of materials you can use to build your shed. Timber, resin, and aluminium are all materials to choose from. However, at Sheds Direct, we think the best option for durable, long-term use is steel sheds. We focus exclusively on steel kitset sheds because of their versatility and durability. But how long do steel sheds last? And what factors can affect their lifespan? We cover a few things to keep in mind when choosing the material for your shed. 

Steel framing for sheds

As the bones of your shed, the framing is extremely important. If the framing falls apart, so will the entire shed. It’s essential to choose framing that will last. 

Wood-framed sheds are prone to rotting, especially if the wood isn’t treated properly. Insects can also get into the wood and make nests directly in the material, which can significantly reduce the lifespan of the framing if left untreated. 

Steel framing has no risk of rot and has extreme durability against the wind. A well-built steel-framed shed isn’t going anywhere except in the most extreme conditions. Steel doesn’t bend easily and is also resistant to heat beyond the temperatures we ever see in NZ. Water can be a potential problem because of rust but additives can make it so that rust is practically a non-issue in most situations. 

All of these advantages mean that the steel framing of a well-built shed can last upwards of 50 years. 

Steel paneling and walls

While the framing is the most essential component of the shed, walls and paneling also need to be long-lasting. One benefit of using steel is that components can be cut precisely for a perfect fit. They can also be built in any weather without any changes from warping. Steel also provides superior protection from the elements so wind and water won’t leak through. 

Steel keeps up rather well with minimal maintenance as well. This helps them to last a long time without having to do regular upkeep. Occasional hosing down and cleaning out gutters (if you design has them) is about all they need to last for many years. 

Steel sheds are stable and secure

One reason steel sheds last so long is that they are more secure than other types of sheds. Breaking through the walls is challenging for both weather and intruders so your contents will stay safe. 

Fire isn’t as much of an issue for steel sheds either. Steel has a very high melting point and is non-combustible, so it won’t catch fire from external sources. The toughness of steel also means it can withstand higher forces like debris from windstorms without taking critical damage. 

Steel shed guarantees

Because steel lasts long and works in so many different environments, most shed suppliers offer a long-lasting warranty for steel framing. It’s not uncommon to have a warranty of 25 or 30 years for the framing. 

Here at Sheds Direct, we’re confident that our steel sheds will continue to last because our sheds use 40% more steel than some other suppliers. That’s why we offer a 50-year structural warranty on steel framing. All our colorsteel sheds also come with a 15-year warranty so that you can be confident that your shed will last and continue to look great.
