Reliable and Cost-Effective Storage Unit Buildings

Custom Metal Storage Unit Builders

Storage units have become a very popular real estate investment in Iowa and Illinois because they usually pay themselves off in less than five years. The storage unit business is unique in that the building itself is your feature product, making it perhaps the most important part of your business.

The Benefits of Metal Storage Units in Iowa and Illinois


Whether owning standard or mini storage facilities, it is important to have a durable, climate-controlled storage building that is large yet does not require a lot of maintenance. Our metal constructions provide benefits such as:

  • Economic advantages: Steel is not only strong, durable, and extremely long-lasting, but it is also environmentally friendly. Additionally, it is easy to construct and keeps the cost to build your storage units low.
  • Ongoing cost efficiency: We use the most reliable and effective insulation techniques, to help lower the utility bills for your climate-controlled storage building.
  • Safety and Control: The durable material that we use keeps out bad weather and unwanted insects and pests. It also resists mold and mildew, keeping your facility clean and fresh without significant maintenance.

When done right, building storage units can be a simple process and a great investment that will bring you much profit. With unmatched service, quality materials, and an expert in-house crew, you can trust Greiner Buildings with your standard or mini storage unit construction. Contact us to get started!
