voestalpine Metsec eaves beams are designed to provide an unobstructed side sheeting face by the use of counterformed web holes that accept 16mm diameter countersunk set screws.
The packing plate accommodates the counterforming and enables standard eaves braces to be fitted, though the overall length of the eaves brace needs to be reduced by 6mm.
Plain web holes can be supplied and in such cases, the packing plate is not required and conventional 16mm diameter XOX bolts are used.
Download our purlin technical manual in the downloads section at the bottom of the page for more information.
Side rail support systems up to a sheeting height of 10m (see page 39 for recommendations) can be suspended from the bottom flange of the eaves beam. In such cases, a stiffening cleat (galvanised finish) must be included and the eaves brace overall length reduced by a further 6mm (cleat thickness).
* Overall length of eaves beam is column centres less half column width each end less 20mm (i.e. 10mm each end).
Overall length of eaves beam is column centres less 6mm (i.e. 3mm each end).
End fixing cleat (supplied by others) bolted or welded to column.
Material – 6mm mild steel galvanised finish
Web holes can be plain or counterformed to suit the fixing requirement.
