![]() ![]() They are the most suitable solutions for construction projects that require long spans and flexible space. These are used in a wide range of industrial and commercial buildings. ![]() After being manufactured in factory-controlled environments and are delivered on-site in semi-assembled form, where final installation takes place Steel Roof TrussĪ lightweight steel roof truss does not provide too much of a strain on elements such as walls, ceilings etc. They are fitted according to all of the necessary design choices and modifications. Therefore, the trusses that arrive at the job site are constructed exactly as designed, with minute variations. Steel roof trusses are pre-fabricated in factories under stringent quality control. Web bracing: there are members that enable the joining of bottom chords together in a triangular pattern.Bottom chord: is the bottom horizontal that carries combined stress from both tension and bending of the truss.Top chord: it is an inclined or horizontal member used to create the upper perimeter of the roof to resist live load.Components of steel roof trusses Ī roof truss consists of three main components namely, top chords, bottom chords and web bracing Steel roof trusses main functions are to carry the roof load and to provide horizontal stability. All the joints in the truss members have pinned connections such that no shear or moment forces are transferred from member to member. Each triangle unit is constructed with two top chords, a bottom chord, and webs, all connected at the ends by joints. as the individual finished elements are large, transporting them to the construction site can be challenging.A steel roof truss is a structural member element that adds strength and support to roofs.for large or complicated roofs, steel trusses may prove to be an uneconomical solution,.steel trusses cost more than their wooden counterparts,. ![]() due to its low weight, heavy roofing, such as ceramic and especially cement tiles, cannot be laid on it,.although it does not require regular maintenance, regular inspections are required,.although the steel roof structure is effectively protected against corrosion, if this protective coating is scratched, it will become susceptible to corrosion,.corrosion proofing must be carried out,.Steel roof trusses also have their disadvantages. at the production stage, steel elements are covered with special additional protective and anti-corrosive coatings.ĭisadvantages of the steel roof structure.unlike wooden rafter framing, the one made of steel will definitely not be inhabited by insects, pests or parasites,.it has high resistance to adverse weather conditions,.moisture resistance (however, it must be properly prepared beforehand) – this prevents the appearance of mould or fungi,.steel roof trusses can be lighter than wooden rafter framing,.properties of steel – it does not require drying out or maintenance,.it is easy and quick to erect – compared to timber framing, its installation is less labour-intensive and does not require a large number of workers,.The steel roofing structure is delivered to the construction site semi-finished and then put together. ![]() Companies that manufacture and sell steel roof trusses usually also offer its installation. However, it is prepared according to the delivered design, taking into account specified dimensions. The steel roof truss is usually purchased as a finished product. Steel roofing is also used for large-area buildings, such as warehouses and supermarkets. In these cases, a lightweight steel roof structure is used, as it puts a minor load on the walls and ceilings. The steel roof truss is also used in roof rebuilding – particularly when a flat roof is converted into a pitched roof. So when is it used? Steel roof structures are primarily used in buildings and houses which walls are also based on a steel frame. We look at the use, advantages and disadvantages of a steel roof structure.Īs mentioned in the introduction, the steel roof truss is becoming increasingly popular. However, steel is an increasingly popular material for rafter framing. It is not only a traditional material but still the most commonly used. Traditionally, the roof structure – rafter framing – is made out of timber.
