Steel joints are a direct derivative of the steel structures geometry and cross-sections.
Therefore, the changes made to the geometry of the steel structures and its cross-sections has a direct influence on the type of joints that can be designed. 

In the application found below, a typical K-joint of a truss is shown. In a K-joint, steel contractors generally prefer the joint to be a gap joints instead of an overlap joint. Gap joints are easier to built, since the members will be single cut and will therefore be less sensitive for tolerance. In overlap joints, one of the members will sawn with two cuts, making the joint sensitive for tolerance, since the member needs to be an exact fit.

The application shows how different variables are of influence in determining whether the joint is a gap joint or an overlap joint.
