Steel Building Construction

Substantial anchorage of any building eave and ridge ends is required for adequate purlin bracing within steel building systems. Sag angle and/or strapping in basic parallel rows, a customary building technique, does not necessarily stop breakdown and collapse of this procedure.

A row of purlin bracing needs to be adjoined to a sound ridge angle or a channel along the ridge. To help with counteraction to the pressure developed by the accrued force of bracing from a double-sloped rooftop is why this is crucial. It is not enough to install a basic sag angle along the ridge.
