MAXIMUM AND MINIMUM THICKNESS OF FIXED ELEMENTS:
  • h min – when connecting steel sheets together is the minimum thickness of those sheets. when connecting steel sheets to wooden substrate is the minimum thickness of the steel sheet that can be fixed
  • h max – when connecting steel sheets together is the maximum thickness of those sheets. when connecting steel sheets to wooden substrate is the maximum thickness of the fixed elements. Is the sum of: the thickness of the steel sheet and the thickness of components located between the substrate and steel sheet or the thickness of the air gap. The minimum embedment depth in wood was already counted
