Safe and Secure Growing Options

At American Steel Structures, we provide high-quality, steel buildings for use as indoor marijuana growing structures. Our buildings can provide a weather-controlled atmosphere in which to grow and cultivate your crops with added 2" vinyl-backed fiberglass insulation. The clear-span interior provides adequate space for ventilation, lighting, irrigation systems and humidity monitoring systems. It also ensures that you have plenty of room for your growing tables. A steel building works well with security features to prove you with a high level of protection, ensuring that your crops and equipment remain safe.

Steel Marijuana Buildings offer Versatile Design Options


One of the essential accessories for marijuana grow houses is insulation. It is necessary, particularly for buildings situated in areas that have warm temperatures and high humidity. Insulation is crucial since it keeps the growing environment free of condensation and airtight. Condensation can be a big problem in buildings, and a vapour barrier can reduce the amount of condensation inside the insulated steel structure.

In colder climates, the insulation provides protection against condensation caused by exposure to frost, ice, and drastic temperature changes. For those in warmer climates, it helps to reduce heat generated by solar radiation. You are able to purchase insulation from us that is specifically measured to fit your structure and suited for your area and needs.


Structures used to grow marijuana need ventilation as the plants require fresh air to thrive. Vents are necessary to regulate odour, humidity, and temperature. Vents are essential in warmer climates since they reduce heat buildup inside the steel building. Bad air quality can negatively affect the growth and development of marijuana plants. Vents only allow air to pass through, which reduces heat buildup and keeps out insects and birds that can interfere with the growth of marijuana plants.


When growing marijuana plants, sunlight is crucial. With skylights, you will have plenty of natural light in your grow building. Our skylights can resist the effects of high winds, flying debris, and even dangerous hail. Our team will help you determine the ideal locations for installing skylights inside your marijuana steel building.

Steel Marijuana Buildings Can Help in Micromanagement

Steel buildings make micromanagement much easier. Every marijuana strain needs different atmospheric conditions and regulation of these conditions to guarantee healthy growth and development. For growers with multiple marijuana strains, a single grow facility will require varying humidity levels, temperatures, and different stages of growth co-existing in the same steel building.

Cultivating cannabis also necessitates equipment mounted from or on the ceilings, such as HVAC systems, lighting systems, plumbing, mechanical, electric, watering systems, indoor blowers, and condensing units. These devices will significantly increase your collateral load and need a structure that can withstand everything. The durability, affordability, and performance characteristics of metal structures make them ideal for your cannabis needs.

The Advantage of Steel

Compared to structures made from more traditional materials, a steel building goes up faster and doesn’t require architects or large construction teams. They are also quite cost-efficient and offer value and reliability for long-term performance. Should you need additional space in the future, your metal building can also be expanded quite easily to accommodate more abundant crops, processing and selling facilitiesoffices and storage.

Our metal growing facilities can also be used for traditional crops as garden centers and nurseries.
