Purlins

Metroof Zed Purlin

Zed Purlins are manufactured from MS and pre-galvanised steel coil to BS EN 10147.1992 specification giving guaranteed minimum required yield strength, cut to exact length and suitably packed.

The overlap Connection System is mostly used for long spans in large buildings as it gives additional strength and stiffness over the rafter area. METROOF's loading tables are provided and purlins are prepunched as per METROOF's standard punching. The data are only applicable for buildings with 3 bays or more. The loads are those which may actually be applied, the purlin weight has already been deducted.
