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

Metal Greenhouses

We manufacture greenhouse buildings in all shapes and sizes. Our custom steel greenhouses come with a 50 year warranty so you can rest assured that they will stand the test of time. Typical greenhouse applications are hydroponic or non-hydroponic. Worldwide Steel Buildings’ focus is on the production greenhouse market for use as both hydroponic and non-hydroponic grow facilities. Through our 30+ year history in business, and the knowledge of this market, Worldwide supplies custom greenhouse building kits that can be adapted to any climate and conditions.


Because our columns and framing are made from 100% steel, our buildings are not susceptible to wood rot like conventional construction. 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.


Worldwide Steel Buildings’ design allows wider column spacing then the standard 5′-6′ spacing, giving you more space and light. 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. Our buildings are available in a gabled, single slope or asymmetrical design with option 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.
