One-stop shop

Coresteel is your designer, engineer, manufacturer, and builder all in one. Instead of dealing with multiple suppliers and conflicting timeframes, we will streamline the building process and make sure your steel shed is delivered with ease.




Over the years we have completed hundreds of metal sheds. Using our flexible designs and innovative construction methods, we cater to everything from large storage sheds to custom-made kitset sheds and everything in between.


Lasting strength

We pride ourselves on providing strong, durable, and structurally superior sheds. All of Coresteel’s steel sheds are pre-engineered to withstand site-specific wind and earthquake loadings, as well as local council requirements.
