Notes:

1. Values have been calculated as described in the‘European Recommendations for the Design of Sandwich Panels’ (ECCS), taking imposed loads, temperature and creep into account.
* The values shown are SLS loads. (Service limit state or “Working” loads)

2. For each value individual and combined load cases with appropriate load factors and temperatures have been considered.

3. The table is for medium and light coloured panels, as recommended for roofing purposes.

4. The following deflection limits have been used:
    Downward loading L/200
    Suction loading L/150

5. For intermediate values linear interpolation may be used.

6. The actual wind suction load resisted by the panel is dependant on the number of fasteners used and the material of the purlin. The fastener calculation should be carried out in accordance with the appropriate standard. For further advise please contact Ward Technical Services.

7. The allowable steelwork tolerance between bearing planes of adjacent purlins is +/-5mm.

8. Load span tables for panel specifications not shown are available from Ward Technical Services.
