Wood trusses used in the same material must meet very specific criteria regarding their moisture and composition. The top and bottom are called “strings”. The vertical and angled wood, between the upper and lower chords, is known as “lattice”. Wood truss is held together by metal plates that are pressed when the timber is on the board where it is assembled. The wooden trusses can be ordered Architectural degree, so that their components have a finished look and can be left exposed.
King and queen
The king post truss and post queen is very similar to a type of roof supports used in post and beam construction, and are generally specific for short periods, below 22 feet (6.7 m). The lower cord and the fabric is left often exposed to create a vaulted ceiling with detailed architectural. Modified versions of this truss allows them to cover greater distances. There is also queen scissor trusses that offer higher load capacities Some standard scissor trusses.
Scissors, inverted twice, raised central bay three-piece
These trusses and vaulted ceilings create “cathedral”, with large spaces. Scissor truss is usually used in homes, while the double inverted and raised central bay three pieces trusses are used for commercial purposes and for churches.
Fink, Howe, Fan
These are the workhorses of modern trusses and can support a variety of spaces and loads, especially roofing. The amendments increase their capacity and cargo space. Modified versions of these trusses include double Fink, double Howe, as amended Fan, triple triple Fink and Howe.
Single and double
Simple trusses are often used to shed style roofs where the roof slope falls in one direction, usually the front of the building back. The double has two steep slopes at different lengths. These are the most common in pitched roofs where the ridge of the roof is off-center.
Gambrel room, attic, Polynesian
The gambrel roof creates a barn type with three different peaks. By its nature, the trusses have trusses that stand intentions to do something in the attic space. That problem is solved with the truss attic room with its large open center and its bottom with a sufficient load-bearing floor size cord. Polynesian truss creates a single line of Asian roof with two subordinate ridges below the high central ridge.
These trusses result in flat roofs and floors and come in many arrangements to accommodate loads, spaces and building designs. They are often applied with a resin when used for roofing, to help move moisture drainage points along the edges.
