Butt Purlin System

Butt Purlin System

Single/odd BaysLayout and Detailing.

The butt system is suitable for buildings with single bays or more, up to and including 25° roof pitch.

The butt system offers a simple cleat connection and is intended for smaller buildings, short or uneven spans, or light loading conditions.

The butt system caters for spans of up to 12m depending on the load to be applied and where the cladding or liner tray offers adequate lateral support by virtue of its screw fixings at 600mm maximum spacings to the purlins. This system can cater for single bays and can therefore be used in conjunction with other Metsec systems, or as a system in its own right.

Computer controlled production techniques apply the client’s individual mark numbers to all purlins automatically during the manufacturing process.
