  • Stronger Frame

    Designed with strength and quality in mind, our sheds use top quality colorsteel. All of our sheds are fitted with a line of bracings around the height of the wall. For large sheds, there is arch support extending all the way to the ground.

  • 2m Tall Walls

    Steelmates garden shed has a minimum height of 2 meters for wall and door, which is the lowest height of the whole garden shed. There is robust headroom and allows you to move freely inside the garden shed.

  • Steel Thickness

    Most garden sheds use 0.22–0.25mm steel, while Steelmates uses a thicker 0.32mm steel — around 1.4× thicker than average. This added thickness delivers superior strength, rust resistance, and long-lasting durability in all weather conditions.

  • Free Anchor Kits

    Every Steelmates garden shed includes a free anchor kit, keeping your shed secure in all weather and saving you the cost of buying anchors separately.

Shed Foundation Basics

A foundation is essential for a garden shed because it keeps the structure stable, level, and securely anchored. It also raises the shed off the ground to prevent moisture damage, leaks, and door alignment issues over time.

Pretty sturdy shed that we are very happy with. Purchased the 3.39x2.55 and had the ""kitset assembly"" guy put it up. Rather than spend a frustrating number of days attempting it ourselves.

Good value for money, I definitely had to improvise a bit as the instructions were not clear but it is a pretty solid shed.

I began to know about your product when I visit one of my best friends, whose father recently bought one from you. Seeing the appearance and touching the external material, I quickly asked my friends the way to buy it. Unfortunately, maybe it is the best-selling one, no stock when I bought. The staff adviced me another similiar one. Like this one, outside is good and sturdy. Space can be saved now. If possible, the second one will be on the way.

Mmmmmmm.......didn't really go that great. Unfortunately for these guys the freight company (TIL) they use let them and all their customers down bigtime!!!
3 weeks till I finally got it and that was only because I was on their back every other day.
They apparently lost the first one!! Only weighs 100kg!!
They finally had to send it with Mainfreight and I still had to go pick it up!
Victor did however refund my freight charge and did try and get it sorted.

paid for the shed on the 7th was told it was shipped on the 11th but the rubbish freight company says they picked it up on the 20th by the 25th i starting asking more questions and even though i paid for delivery to my address i had to then go and collect it myself from the depot on the 26th. thats over 3 weeks to get the item i payed for immediately from Auckland to Palmerton North! Til is crap at their job so i guess this should probably be a red face feedback
