High Bay/Internal Walling Load Table

< Back to Load Tables

For uniform horizontal pressures greater than 0.45kN/m² use external walling tables.

Where height exceeds practical rolling length a splice detail will be required. If this is the case consult our technical department.

Maximum heights in above table based on:

  1. Unfactored horizontal pressure.
  2. Deflection limited to height/240.
  3. Blocking and strapping at mid height.
  4. Studs are boarded with a minimum of one layer of 12.5mm (min) plasterboard to both sides.
  5. Studs fixed into 1.2mm base track.
  6. 100mm, 150mm and 200mm studs fixed to Metsec Slotted Deflection Head Track.
  7. 70mm, 250mm and 300mm studs fixed at head using standard 2.0mm head track with blocking and strapping detail.
