What are our customers saying?

“I am delighted with this shed. Fantastic size, great quality, easily constructed by the kitset man for a very reasonable price. I am going to replace our other old shed with a smaller version very soon, as I am so happy with it.”

“Great value for money. Two people constructed the shed. The materials supplied are well-suited to the job, and the shed is easy enough for a novice to construct. The shed is very smart and looks great.”

“I really enjoyed assembling this shed, with easy-to-read instructions. Went together well and sit well on the wooden floors I made.”

Frequently asked questions

What is the life expectancy of a steel shed?

Garden sheds made from high-quality galvanised steel can last between 20-30 years or even longer if properly cared for. On the other hand, neglected sheds made from low-quality materials will only last around 10 years, on average. At Trade Tested, we’re confident in our steel sheds’ reliability, which is why all sheds come with a 12-year guarantee.

Do you need a foundation for a steel shed?

Yes. All sheds require a solid foundation to keep them functional and in good condition. Foundations offer a secure, level base above steel to prevent moisture from pooling, while ensuring even weight distribution. For steel sheds, we recommend either concrete shed bases for something permanent and robust, or a timber base for a movable, lighter option.

Do metal sheds get too hot?

Yes, metal sheds can get hot on the outside and heat up the interior. To manage this, we recommend choosing a light coloured shed, picking a partially shaded placement for your shed and equipping it with insulation and ventilation.

What is the maximum shed size without a permit in NZ?

In NZ, you can install a detached, single-storey garden shed up to 10m² without council consent. At Trade Tested, none of our sheds require a permit. They’re good to go!

Do steel sheds get damp?

Yes, steel sheds can get damp from condensation, but with a proper shed foundation and some ventilation and insulation, your shed will be best positioned to stay protected against the effects.
