The concept of using steel instead of wood for a roof truss is not new. A few years ago, it was considered a good option for the environment because it does not require the use of a lot of wood, which is a resource that is not only expensive but also harmful to the environment. However, in the past few years, this technology has received a bad reputation because some of its products are not safe for use. For example, there is a risk of the truss becoming contaminated by the elements because the truss is made of steel.

What is the difference between steel and wood?

The main difference is the way in which the truss is made. With steel, you have to use a special process for making the truss, which makes it lighter. In addition, you have to be careful when installing the truss, and you have to make sure that the joint is well sealed. With wood, on the other hand, you can simply use a normal roof joint, which is a good option for the environment.
