A folded plate roof is best described as an assembly of flat plates, or slabs, that are bent in different directions and joined at their longitudinal edges. The way the structural system is connected makes it capable of carrying loads without requiring the use of additional support beams.
These structures are typically built on-site of precast reinforced concrete, steel plates, or tempered glass. Various shapes include rectangles, pyramids, prisms, and non-rectangular shapes. Since folded plate architecture is less material-intensive than other types of roofing systems used for commercial applications, they’re also usually less expensive.
The folding plate structure originated in Germany in the 1920s when it was used for an aircraft hangar at the Orly Airport in Paris, France. The roofing type became commonly used for immense factory buildings and coal bunkers throughout central Europe. It was introduced to North America during the 1930s after World War II.
This roofing type is most often used for industrial and commercial applications. However, it can also be used for mid-century modern homes. We suggest contacting your local roofing experts if you’re interested in the folded plate roof design. They’ll be able to help you decide what would be best for your property.

Folded plate roofs can be constructed from a variety of high-quality materials. Ones that are the most often used include steel plate, reinforced concrete, or tempered glass. In the sections below, we’ll discuss each material in detail to help you make a more informed decision.
When you’re installing or replacing a roof, it’s a good idea to consult with an expert to determine which style of roof and material will work best for you. We recommend getting in touch with your local roofing contractor to get started with your project. They’ll be able to walk you through the process.
Material 1: Steel Plate
Steel is one of the most commonly used materials for this roofing type due to its strength and durability. Steel folded plate roofs not only provide an interesting appearance but also offer the option of having large column-free areas. As for design, a standard module that’s open to prefabrication was created. Design charts have been prepared by experts, and they can be used for the preliminary design of steel frame folded plate roofs without having to use rigorous computer methods. Property owners interested in using steel can contact their local roofing company to get started on their project.
Material 2: Reinforced Concrete
Reinforced concrete is another one of the most popular materials used for folded plate roofs. Like steel, it’s known for both its strength and durability. The basic idea of creating a concrete folded plate roof was to achieve more constructive height and better rigidity while reducing the overall weight of the structure. It’s noteworthy to add that the strength of this type of construction is achieved through the proper design rather than the materials that form it. If you’re interested in concrete folded plate roofs for your property, get in touch with a local roofing contractor as soon as possible.
Material 3: Tempered Glass
Last but not least, tempered glass is the third material that’s most often used for folded plate roofs among property owners. You can use either glass alone or combined with other materials to make various roof, wall, and floor constructions. Whether you select glass or another type of material for your folded plate roof, you can rest assured that the structure will have an intrinsic rigidity and high load-bearing capacity. If you’re a property owner who would like to install tempered glass on your home or business, please do not hesitate to call your local roofing contractors.
Once you’ve decided that you’d like to install a folded plate roof on your property and you select the material, then it’s time to determine which type of structure would work best for your building. The five main structure types include butterfly-shaped folding plates, V-shaped plates, tapered folding plates, trough-shaped folding plates, and hyped folding plates.
Folding plate structures are assembled using flat plates, then they are bent in different directions, and finally joined along their longitudinal edges. Modern ones are typically precast steel plates or reinforced concrete. As a shell structure, they consist of a series of thin plates, also known as hipped plates. Folding plates cover large areas, while bent plates are used to cover smaller areas.
In the next section, we’ll discuss each type in more detail to help you decide. You can also get in touch with your local roofing company to receive a consultation with an expert.
Butterfly-shaped Folding Plates
Butterfly-shaped folding plates may not be as widely applied as other types, but they still have their uses. It’s important to keep in mind that they’re commonly used to cover petrol pump roofs and factory roofs as well as provisions for windows.
Among the different types of folded plate structures, V-shaped tend to be the simplest. These types of plates are normally used for short spans since they don’t offer enough surface area for concrete, the bottom, and the top to resist compressive stresses.
Tapered Folded Plates
In many cases, tapered folding plates are mainly used for aesthetic purposes. It’s also important to remember that Z-shaped folding plates are only used for factory construction. The reason for this is that they provide a north-light roof.
Trough-shaped Folding Plates
Unlike V-shaped plates, trough-shaped folding plates will provide sufficient surface area for concrete at the top. They can also resist compressive stresses at the bottom. This type of plate can be used for a long time.
Hyped Folding Plates
Hyped folding plates are a structural type that’s mainly used for two types of projects. These projects include cooling towers in thermal power stations and also tent-shed roofs.
If you’d like to learn more about the different types of folding plates, schedule a consultation with your local roofing professionals.
Not a real zip code.
Not only are folded plate roofs easy for architects to design, but they also offer plenty of design options for property owners. The best part is that they can make any building visually appealing while remaining highly functional.
If you’re wondering what shape would work best for your building, you should research and review the different shapes and overall forms that are available to you. In the next section, we discuss three of the most popular shapes including prismatic, pyramidal, and prismoidal.
If you’re seeking the opinion of an expert, we recommend getting in touch with your local roofing contractor.
Prismatic (Rectangular plates)
Folded plate structures consist of flat components, known as plates, that are connected along their longitudinal edges. Prismatic is one of the primary types of plates that property owners can select for their roofing structure. What differentiates them from other types is the fact that the plates are rectangular as opposed to another shape. In modern construction, the folded plate structures that are most widely used are made of precast reinforced concrete or cast-in-situ.
Pyramidal (Non-Rectangular plates)
Pyramidal is another one of the main shapes used for folded plate roofing structures. It’s best described as a type of non-rectangular plate. Property owners who’d like to see how pyramidal plates would look on their building should get in touch with their local roofing contractor. Many contractors offer consultations to give owners an idea of what’s best for them as well as a price estimate.
Prismoidal (Triangular or Trapezoidal plates)
The third folded plate shape that we’re going to discuss in this section is called prismoidal. This type is best described as triangular or trapezoidal plates. Depending on the type of appearance you’re going for, prismoidal may be an ideal choice. A roofing professional will be able to review your options to determine which type would be best for the preferences for your building. Folded plate construction is beneficial because it’s simpler to manufacture and requires less material than other types of roofs.
If you’re interested in folded plate roofs, then you probably have plenty of questions. In this section, we’ll answer some of the questions that our team is most frequently asked about this type of roofing structure. If you’re still interested in this roofing style, don’t hesitate to get in touch with your local roofers to schedule a consultation.

These structures have a more intrinsic rigidity and higher load-bearing capacity than other types of roofing structures. They’re beneficial for property owners because they don’t require additional supporting beams along their mutual edges.
First introduced into the United States in the 1930s, this roofing system quickly became popular for large industrial and commercial buildings.
