If you want to build a flat roof then you will need to build a flat roof truss these are designed to span the space between two load bearing walls and take the weight from the roof onto these walls.
The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers.
They are commonly found in a wide range of building types such as factories warehouses agricultural buildings.
Alpine truss designs are engineered to meet specific span configuration and load conditions.
In the engineering and construction industry any truss spanning more than 60 feet is considered to be long span thus requiring engineering consideration per international building code ibc 2015 section 2303 4 trusses for design of.

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge.
A flat roof truss is also known simply as a flat truss and is not completely flat but rather slightly sloped in order to allow water to run off of the roof.
These steel joints are needed to support the overall truss.
