• Recommended working loads valid for fastened materials as shown above.
• For intermediate sheet thicknesses, use recommended load for next smaller thickness.
• For stainless steel sheet, use same loads as for carbon steel sheet.
• Recommended loads include an overall safety factor applied to the characteristic strength.
Static test: Nrec = Ntest,k / 3.0 Vrec = Vtest,k / 3.0
• These recommended loads are appropriate for Eurocode 1 (or similar) wind loading designs.

* Fastened parts: thicker steel components (clips, brackets, etc.)

• Failure of fastened material is not considered in Nrec and Vrec.

• Loads valid for predominantly static loading.

Forces of constraint
When fastening large pieces of steel or aluminium, the possibility of shear loadings from
forces of constraint should be considered in the fastening design. Either allow for movement
or avoid exceeding Vrec!

Deflection due to primary loading Temperature effect
