How Roof Trusses Are Made

March 6, 2018 0 Comments roof-trusses

In previous posts, we have explained the anatomy of a roof truss and the difference between site-made and prefabricated roof trusses.  In this post, I will explain how roof trusses are made.

The process will vary slightly depending on available equipment, but the principles will stay the same globally. However, there are a few basic steps that will stay the same regardless of where you are.  Here is a short description of our manufacturing process:


After consulting with the client, architect and builder, site measurements are taken and the information is conveyed to a qualified designer for processing.  Using sophisticated software, a complete roof is designed according to all relevant specifications and Building Codes.  A Cutting bill is generated for each individual truss in the roof which is then sent to the factory. 


Timber is selected according to size and grade specified on the cutting bills.  Each member of the truss is then pre-cut to the specified length and angles using cutting equipment specifically designed for the roof truss industry.  


Magnetic based pedestals are accurately positioned on a steel floor to form a jip or template in which all the pre-cut components are assembled, much like a jigsaw puzzle.


The designed nail plats are placed in position and a gantry mounted c-clamp hydraulic press is used to press the nail plates into the timber. In some cases, a timber template is used for assembly purposes, in which case the nail plates are pressed in using a roller press.
