Section beam

Section beam

Section Beams are made of steel and they have a specific lengths and shapes like I-beam, L , channel and I flanged beam. These types of section are usually used in steel structures and they are connected by plates of steel too.

Joints

There are three methods of connection and they are :

* Rivets
* Nails
* Welding

The strongest method of connection is the riveted method and it is the most used one. Fact|date=November 2007

There are some methods of calculation to see if the design of the truss or the construction is safe or not. Fact|date=November 2007
