Canary Wharf is a major business district in east London, within the London Borough of Tower Hamlets. It is one of the United Kingdom's two main financial centres â along with the City of London â and contains many of Europe's tallest buildings, including the second-tallest in the UK, One Canada Square.[1][2]
Trusses and rafters are both assembled ahead of being installed onto the roof. Trusses are assembled in a factory using pre-engineered structures and joints. On the other hand, rafters are assembled at the construction site. As trusses are assembled in a factory, a lot of time can be saved.
In houses, trusses are commonly used in the construction of the roof and the floor. In roofing, the truss may be used to frame the roof, while in flooring, a truss can be used to create a platform. Many large, open platforms can also be constructed with the use of trusses.
