z-section

The section reference of a Z-section 232mm deep and 1.8mm thick would be 232 Z 18. The first 3 digits of the section reference indicate the depth of the section in millimetres (i.e. 232 equals 232mm deep).

The fourth digit is a letter that signifies the profile type (ie Z for Z-section). The last two digits indicate the material thickness (i.e. 18 = 1.8mm).

Take a look at our purlins technical manual located in the downloads section below for more information.

Sleeves

The sleeve reference is the same as the purlin it is being used in conjunction with, except that it is prefixed with ‘PS’ for a standard sleeve and ‘HEBS’ for a heavy end bay sleeve ie:

  • PS 232 Z 18 standard 232 Z 18 sleeve
  • HEBS 232 Z 18 heavy end bay 232 Z 18 sleeve

All Metsec Z-section product is manufactured from pre hot dipped galvanised steel to BS EN10346:2015, Z275 coating and with a minimum yield strength of 450N/mm².
