![]() This is quite a popular truss structure and can be easily identified by its construction of equilateral triangles. Howe truss styles have very wide spans, ranging between 6 and 30 meters, which makes them very versatile and suitable for a wide range of applications. Most of the truss is made of wood, while the vertical or tension members are made of steel, offering additional support. Howe truss shapes is essentially a combination of wood and steel, which makes the design elegant and appealing. Pratt trusses can be used for spans ranging between 6 to 10 meters. This produces a very efficient design and helps to reduce the self-weight and cost and also helps to ease the structure’s constructability. Pratt types of trusses consists of vertical members, which are in compression and the diagonal members, which are in tension. This is among the most popular steel roof trusses and is very cost effective. This is an effective truss method that has been in use for more than two centuries. The queen post roof truss designs offers a good span of around 10 meters and the simple design makes it excellent for a wide range of applications. It consists of a vertical upright and two triangles on either side. Generally, queen post trusses are simple, reliable, yet versatile roof trusses that can be used any time at all. Several old buildings also feature visible king post trusses. King post roof truss types are usually used for short spans, which makes it ideal for smaller houses, porches, garages, outbuildings, etc. The king post truss is usually made of wood however, sometimes it is also made of a combination of wood and steel. Read on to get a complete lowdown on the different kinds of roof trusses and their applications. These parts of a roof frame not only matter for structural integrity but for attics or storage space, heat dissipation, and more. ![]() It is very important to select the right kind of roof truss that will suit both your project, as well as your budget. The goal is to distribute load and reduce forces like torsion, tension, compression, shearing, and bending. This is all material science and civil engineering built into trusses. So, whether you are building a large-sized agricultural structure, a home or any other project, roof trusses are a very important part of the style, structure and cost of the building. The types of roof trusses you choose can impact the final building. However, not all roof trusses are the same and they come in varied sizes and shapes. The key function of roof trusses is that they carry the loads from the over-structures and provide lateral stability to the whole structure. Since the roof truss has to support the entire weight of the roof of the building, they must be extremely strong and stable. Triangles are generally quite efficient, allowing good load control and so, they are commonly used in construction. Trusses are the most popular form of roof framing and provide a more flexible, affordable and quicker installation of roofs.Ī truss is basically a triangular construction, which includes triangular shapes in different configurations to fit the design, size and pitch of the roof. Roof trusses are of two types: pitched and flat. Also called trussed rafters, all of the various roof types of trusses are essentially prefabricated structures that help to support the roof on a building.
