A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below).
Despite their simple structure, Kingpost prefabricated trusses can be used for a variety of purposes. Their suitability to span up to 4 metres makes Kingpost trusses a favourite for use in the construction of small house extensions, garages, garden sheds and dormer windows.
A queen post is a tension member in a truss that can span longer openings than a king post truss. A king post uses one central supporting post, whereas the queen post truss uses two. Even though it is a tension member, rather than a compression member, they are commonly still called a post.
Characterised by its central vertical post, known as the king post, this truss type effectively supports the weight of the structure's roof or bridge span. Constructed with wood or metal, the king post truss serves as an efficient solution that distributes loads to support wide spans with fewer materials.
King post walls are a simple and quick installation method. They comprise drilling a hole with a high powered, continuous flight auger (CFA) piling rig, filling it with concrete, then installing an H beam. This allows concrete pre-stressed panels or sleepers to be inserted between the webs of the H sections.

King post truss: Disadvantages
While there are several advantages to using a king post truss, there are also some potential disadvantages that should be considered: Limited span: King post trusses have a relatively limited span, so they may not be suitable for larger buildings or spaces requiring longer spans.
The King Post Truss is configurable in a range of sizes with typical spans between 16'-26' (4.9-7.9 m) and overall heights of 2'8”-13' (.
A king post truss, or turkey track truss, is built with two principal rafters, a tie beam, a central vertical post, and two struts. The central vertical post is what gives the king post truss its triangle shape. For added support, one strut is placed at a 45° angle on each side.
(iv) Queen Post Truss - Span length is in between 8 to 12 meters. (v) Pratt Truss - Span length is in between 6 to 10 meters. (vi) Howe Truss - Span length is in between 6 to 30 meters.
King posts are isolated steel columns or beams that are installed along the line of the proposed retaining wall typically at centres between 1 and 3m. The space between the posts is filled, over the retained height, using a variety of different solutions but most commonly a precast concrete panel.
When properly constructed with tight-fitting, precisely cut joints, the through-tenon King Post Truss provides a sturdy roof structure. The forces follow a clear load path - down the rafters, into the king post, through the tenon, and into the tie beam.
The primary difference between the two is that a king post truss has a single supporting post and a queen post truss has two. Applications of each depend on the size of the roof span, with king post trusses spanning 5 to 8 meters. Due to the double posts, queen post trusses have a wider span, measuring 8 to 12 meters.
Purlin is a horizontal beam or bar used for structural support in structures, most often below the roof. Purlins are supported either by the building's rafters or its walls. These are most commonly used in metal buildings, but in wood-frame structures, these also replace closely packed rafters.

For Example: Calculate the length of the maximum height of the king post in a roof truss to ensure that the slope of the roof is less than 10°. The width of the house will be 40 feet. 40ft tan 8 = opp adj X tan 10° 20 ft 20 ft • tan 10° = x x = 3.52 ft Therefore the king post should be no longer than 3ft 6in.
The distance a 2×6 can span is determined by the species, grade, location, use, load, and spacing. Based on building codes, a 2×6 can span anywhere from 2'-1” to 20'-8” depending on the affecting factors. Ceiling joists don't normally have the same load restrictions, and so can span greater distances.”
Fink Roof Trusses consist of a network of triangles that distribute the load evenly across the structure, providing maximum strength and stability allowing for long spans that are often utilised in commercial buildings.
The triangular webbing pattern of roof trusses makes for a stronger, more load-bearing roof structure and roof deck that can support more expensive building materials. While rafters require additional support to keep the structure standing, trusses get the job done with fewer load-bearing walls.
Trusses cost more because they use the same amount of material, but you'll also be paying for the labor, as well as the delivery to your home. However, if you're having a contractor build the roof for you, then trusses will be less expensive, as the labor costs to build roof framing on-site will cost more.
