- Pre-punched oval holes 14 × 22 mm
Light, straight and pre-punched
C sections are roll-formed from galvanized coil and used as purlins, girts, eave struts and light framing. They are cut to length and punched to the connection layout in-line, so members arrive ready to bolt. Simple spans and short projects use C sections; continuous lapped systems usually use Z purlins.
