How much bearing for the panel sitting on beams do I need?

The minimum bearing required is 30mm. However, for added safety and to prevent any possibility of panel displacement, we strongly recommend using the shear stud on steel beams or the rebate wall on concrete beams to ensure a secure fit. For instance, consider a scenario where a Mek-Dek panel becomes dislodged and moves towards the shear stud, which is positioned 70mm from the face of the stud to the edge of the beam. To determine the recommended bearing length at each end of the panel, simply add the 70mm distance to the minimum requirement of 30mm and then divide by 2. This calculation yields a recommended bearing length of 50mm for each end of the panel, ensuring a stable and secure placement.
