Flat sections are used anywhere where a connection between 2 beams is required. 

 

• Using the first measurement on the chart as an example; 

• ‘40 x 3 flat’

• 40mm = width

• 3mm = thickness 

•  

Here are some of what Flat sections are used for;

• Base plates

• End plates

• In some cases they add strength to a beam when welded along the length of a beam (top or bottom).
