At some point, either as a contractor or homeowner, you may need to order a roof truss. Whether the roof is a simple timber roof or an elongated complex attic, it is helpful to know what information the agricultural designer may need.
Most likely, your construction will come from an architect's drawing and most of the details you will need will be listed there. In more complex cases, there may be technical specifications that include details such as fixing winds and determining loads. A discussion of the different types of timber roof truss structures is beyond the scope.
1. Brief anatomy of the roof structure
You can think of a simple general roof truss as a triangle with two upper chords (rods) of the same height, which meet at the top and are connected at the base by the lower string (top joint). This "close-fitting system" is the main form of most roof structures being developed.
2. General coverage of the roof truss
When measured in millimeters, the total distance to the roof structure is the area above the wall panels. It is defined as the distance between the outer edges of two load-bearing wall panels. The lines of the overhang and roof provide the width of the disclosure; planks are installed under the roof to hide timber.
Facade panels are horizontal panels that are installed along the length of the building and fixed at the end of the agricultural overhang. The fascia itself is usually made of a plastic derivative that is bonded to sun damage.
