Metsec

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).

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:

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.
