A key element of every roof, but also the entire building, is the rafter framing. Traditionally, the roof structure – rafter framing – is made out of timber. It is not only a traditional material but still the most commonly used. However, steel is an increasingly popular material for rafter framing. We look at the use, advantages and disadvantages of a steel roof structure.
Steel roof structure – key information
As mentioned in the introduction, the steel roof truss is becoming increasingly popular. So when is it used? Steel roof structures are primarily used in buildings and houses which walls are also based on a steel frame. The steel roof truss is also used in roof rebuilding – particularly when a flat roof is converted into a pitched roof. In these cases, a lightweight steel roof structure is used, as it puts a minor load on the walls and ceilings.
Steel roofing is also used for large-area buildings, such as warehouses and supermarkets. The steel roof truss is usually purchased as a finished product. However, it is prepared according to the delivered design, taking into account specified dimensions. Companies that manufacture and sell steel roof trusses usually also offer its installation. The steel roofing structure is delivered to the construction site semi-finished and then put together.
