At Simpson Steel Building Company, we specialize in delivering top-tier metal building solutions throughout Rhode Island. Since 1980, we have been manufacturing pre-engineered steel buildings and kits that combine strength, flexibility, and affordability. Whether you are seeking a storage facility, warehouse, agricultural building, or aircraft hangar, our steel buildings provide a durable solution tailored to your needs. Our goal is to make it simple for customers to get a quote, ask questions, or contact us directly for guidance.
Our steel building solutions are designed to provide the strength and reliability of traditional rigid-frame structures at about 30% lower costs. This is possible due to our patented steel truss frame design, which maximizes structural integrity without relying on heavy steel beams. From commercial warehouses to mini storage units, each metal building can be customized to meet local codes and regulations in Rhode Island.
We offer a wide range of pre-engineered buildings, including recreational structures, agricultural buildings, garages, airplane hangars, and more. While we are not a design firm, our kits allow minor modifications to suit your specific requirements. With our truss frame system, you can enjoy buildings up to 50 feet wide and 18 feet high, perfect for non-extreme snow and wind loads common in Rhode Island.
Whether you need a steel building for personal storage, a commercial warehouse, or an industrial facility, Simpson Steel Building Company provides flexible solutions. Our approach ensures you receive a high-quality structure that is cost-effective and easy to install.

Simpson Steel Building Company has been providing metal buildings to the great state of Rhode Island for over 40 years. We’ve become very familiar with and kept up with local building code changes that have come up over the years. Our patented truss design gives you all the benefits of a traditional red-iron structure for a much lower price point! If you are in the higher snow load areas of Rhode Island we offer a Rigid Frame building design that will meet any snow load requirement necessary while also still providing all of the functionality that you need.
Our bolt-together building kits are easy to assemble and only require a forklift or tractor with tongs to move around. This makes our building kit the perfect solution for any Rhode Island residents looking for an affordable DIY Kit for their project needs. Speaking of projects, our buildings work great for a multitude of uses, such as hay barns, stables, garages, shops, commercial buildings, and barndominium homes! In the event that you want someone to erect the building for you, we have a list of local contractors we can refer to help with that aspect of the project.
Simpson can provide complete engineered plans, engineered design calculations, and engineered foundation plans that are stamped by a licensed Rhode Island engineer in the event you need these items for permitting. Most projects in Rhode Island don’t even require engineer stamped items, and in these instances where non-stamped drafted plans will suffice, we’ll remove those unneeded engineering costs and pass those savings on to you!

Simpson Steel Building Company is able to manufacture our high-quality pre-fabricated buildings thanks to our unique steel truss designs. This metal truss is similar in shape to a wooden truss with a bottom cord except made entirely out of quality metal. We also use 26-gauge metal sheeting which is heavier and provides more durability. Twelve-gauge red iron structural steel is also used to provide additional strength and quality.
