What are they? What are they used for?

• A wood truss is a structure comprised of one or more triangular units and framing members, which are connected by metal plates at each joint.
• The triangle shape gives the truss strength and stability.
• Trusses are often referred to as an open web system due to the web-like appearance caused by the triangular patterns.
• Designed to transfer weight of supported load to the joints, rather than to the chords or webs.
• Inteded to give clear spans between the external supporting walls
• Typically, roof trusses are used in residential and commercial construction as an alternative to conventional stick roof framing.
