Some Common types of Steel Trusses

Most roof trusses are easy to customise, but as there are many to choose from it all comes down to you and the building design. Work with a SSS Steel Structures and we will advise on the most suitable steel roof truss for your building in Gauteng. The design options and types of steel trusses are not limited to the ones mentioned below There are also saw-tooth, bowstring, warren, etc. The building type determines what steel trusses will be used
  • The north light: Suitable for the larger spans that go over 20m and get up to 30m. This type of truss gets its name from the placement setup. This method is one of the oldest, as well as most eco-nomical ones that you will find on the market, as it allows for proper ventilation. It is known for its dura-bility and versatility The steel structure has a trian-gular shape with a long gentle slope and a short slope. The short side is generally north facing. Thesetrusses are often used in workshop buildings
  • The pratt: This is one of the most popular steel roof truss types and it is pretty economical. This steel truss is also referred to as the ‘N’ design because of its shape when the structure, often a bridge, is as-sembled. The vertical members provide tension, while the diagonal ones are bringing in compression.In Pratt design, multiple vertical chords are welded to a single diagonal chord which is attached from thetop of one vertical chord to the bottom of another, forming an ’N’ shape.
  • Queen post truss: The Queen Post Truss is designed to be a very reliable, simple and versatile type of steel roof truss that has become very popular. It of-fers a good span, around 10m, and it has a simple setup which makes it perfect for a wide range of building designs
  • The scissor: This steel truss design is used in large buildings such as churches or cathedrals. It doesn’t require beams or bearing walls, however it doesn’t leave that much space for insulation which makes itsenergy efficiency very poor. On the other hand, the upside here is that the ceiling gets vaulted and you receive more space in the attic. The design has two sloping sides in the centre of a large empty ceiling.
  • The Fink: The chords of this design are arranged in easier patterns and shorter distance. This design is good to be used in small buildings such as work-shops
  • Fan truss: You will often see from many steel roof truss designs using the Fan Truss as it is a very simple design. The top chords are split into smaller lengths, as this allows the construction to obtain roof framing members that span parallel to the building eave, and support the roof decking or sheeting. It is possible to get a medium span with this steel fan trusses, around 10-15m, which is ideal for most projects.
