We Manufacture Your Steel Building Kits in the USA & Ship Direct...Worldwide!

Metal Greenhouses

Worldwide Steel manufactures steel-frame greenhouse buildings in all shapes and sizes. Because our greenhouse kits are fully-customizable, you can decide what you want to grow, how much space you’re going to need, and (thanks to our easy assembly greenhouse kits), DIY the construction all on your own – even if you’re a beginner. 

Over our 30+ years in business, Worldwide consultants have developed deep knowledge of the greenhouse market, and use that knowledge to help you design exactly the custom greenhouse kit you need, no matter your climate, conditions or goals. 

While we can help you design anything from backyard greenhouse sheds to very large greenhouses, Worldwide Steel Buildings’ focus is primarily on the production garden greenhouse market for use as both hydroponic and non-hydroponic grow facilities. Both our framing and our polycarbonate paneling are extremely heavy-duty and built to last, so your plants are safe from the elements, moisture, and structural failure.

Steel Frame Greenhouse Kit Durability

Because our greenhouse kit secondary framing materials are galvanized, they are not susceptible to wood rot, pests, or moisture damage like conventional construction greenhouse structures. Our production greenhouses and grow houses are tailored to your specific needs, so no matter what you’re growing, you can rest assured that your greenhouse is built to last.

Even though a greenhouse kit is made of less steel than a typical steel building, because it’s sheeting is polycarbonate, your greenhouse structure’s steel frame material is heavy-duty enough to handle whatever the environment throws at it. This is in contrast to a standard PVC greenhouse, which may be marketed as less expensive, but is much more likely to require repair and maintenance over the years. When you want your growing seasons to last, a steel greenhouse frame is the way to go. 

Plus, all our custom steel greenhouses come with a 50-year warranty so you can rest assured that they will stand the test of time.

Versatility of our DIY Metal Greenhouse Designs

Whether you’re expanding your commercial greenhouse or just starting to explore the world of hobby greenhouse growing, you know how important sunlight is to your growing space.

Worldwide Steel Buildings’ clear span design allows wider column spacing than the standard 5′-6′ spacing, giving you more clear cover space and allowing more light into your greenhouse. 

We supply complete framing kits allowing you to use the solid or transparent panels of your choice. We can also coordinate directly with our polycarbonate panel supplier, allowing for a more complete package.

Plus, our buildings are truly customizable, no matter what you’re looking to DIY. From hobby greenhouses and backyard greenhouses to commercial garden greenhouses, from portable greenhouses to large walk-in greenhouses, Worldwide Steel can help you custom-design greenhouse features for the growing space you need. 

All of our metal frame buildings are available in a gabled, single slope or asymmetrical roof design with options to add a lean-to and overhangs. Main frames can be supplied galvanized or painted with a choice of secondary framing in galvanized tubing, cees or wood.

And here’s a little secret – our DIY greenhouse kits aren’t just for greenhouse growing space. If you’re looking for a sun room for your home, you can work with us to design a steel-frame structure with polycarbonate sheeting to attach to your house. From there, you can even hide the structure’s more typical greenhouse features by paneling sections of it in wood.

At Worldwide Steel, our building kits are truly customizable – to the benefit of greenhouse plants and their owners.
