See How Our Greenhouse Is Built

An independent YouTuber shows exactly how our greenhouse is constructed — no edits, no shortcuts.

Versatile Growing Space

Sleek aluminium finish blends well with contemporary gardens and backyards.
Ideal for vegetables, herbs, seedlings, and flowers in all seasons.


6mm Twin Wall

A twin wall is a common configuration in greenhouses, but the thickness of the panel varies. Our polycarbonate panels are 6mm thick, which sounds like a small difference than 4mm, but it creates 20% effectiveness in heat protection, 5-10% less light transmission. It will also last longer, especially in the variable climate of New Zealand.

Improved Wind Resistance With Door Lock

The greenhouse is able to withstand strong wind from the outside, however, if wind gets inside through the door, the greenhouse becomes vulnerable and some panels may be lifted off. For this new series of greenhouses,, we have added a door lock to keep the door securely closed.

Extensive Reinforced Bracing

Every panel has extra diagonal bracing behind their back, protecting them in severe weather conditions. There are also horizontal bracings added under the peak, which stabilize the structure of the whole greenhouse.

Stainless Steel Fasteners

Upgraded stainless steel bolts and nuts, they are rust proof as the aluminium profiles. It will support the greenhouse for many years to enjoy with peace of mind.

Optimal Ventilation

A well-ventilated greenhouse maintains stable temperatures and healthy humidity levels, helping prevent overheating, condensation, and disease.

These easy-to-open vents can be operated with one hand, or you can get an automatica vent opener.

Polycarbonate vs Glass Greenhouse

Poly Greenhouse


✔ Excellent Insulation: Polycarbonate panels provide superior heat retention compared to glass, helping maintain stable temperatures and extend your growing season.


✔ Impact-Resistant & Virtually Unbreakable: Designed to withstand hail, strong winds, and accidental knocks.


✔Diffused Light for Healthier Plants: The twin-wall structure gently diffuses sunlight, reducing harsh shadows and preventing plant burn.


✔ Energy Efficient & Cost Effective :Better insulation means reduced heat loss, helping you save on heating costs during colder months.


✔ Easy Installation: Lightweight panels are easier to handle and install, simplifying assembly and reducing setup time.

Glasshouse


✔ Maximum Light Transmission: Tempered glass allows more natural sunlight to reach your plants, promoting stronger growth, healthier leaves, and better yields throughout the seasons.


✔ Safer by Design: If broken, tempered glass shatters into small, blunt pieces, making it a safe choice for families


✔ All-Weather Reliability: Built to handle temperature changes, strong winds, and harsh outdoor conditions, tempered glass keeps your greenhouse dependable.


✔ Premium Look & Feel: Tempered glass gives your greenhouse a professional, high-end appearance that blends beautifully into any garden setting.


✔ Easy to Clean & Maintain: Smooth, non-porous surfaces resist staining and can be cleaned quickly

We bought a small Greenhouse from Steelmates and we could not be happier. It is extremely well designed from the aluminium frame right down to the stainless steel fixings. Would definitely recommend

You can see in the picture, regarding the color, structure, and quality, nice quality for the size and price. During the process of assembling, I turned my neighbours to ask for some help. They are so nice and helped me finish it. Thanks to my kind neighbours. Without their help, I might not have had such beautiful greenhouse. Excellent product! Nice neighbours!

So pleased with the greenhouse I bought, so beautiful and so delicated. Well worth the price. Instructions are also easy to follow. I finished it within a full day. You can see in the picture what the greenhouse looks alike. Isn't perfect? For me, it is too much practical, where I can plant. A little pity is that I bought a small one. After thinking for a while, I decided to buy the second that should be bigger.

I previously bought a cheaper greenhouse but the quality of it was extremely worse. Not long ago, I had dinner in a restaurant and saw it used this for outdoor seating during the winter so I determinded to buy a better greenhouse. My expectation is that it was insulated, ventilated, and warm. The greenhouse meets all my expectation and is a desirable one. The design is high quality. Price is worthwhile.
