  • The roll formed Z Section is often used as a wall girt or roof purlin in a structural system. Using thickness between 16 ga (0.060in) and 10 ga (0.135in), standard 

    section widths range from 6” to 14”. The manufacturing equipment allows for custom hole punching, notching, and section dimensions

    Z-section Dimensions and Properties

    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 (ie 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 (ie 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 ‘’ for a standard sleeve and ‘’ for a heavy end bay sleeve ie: PS 232 Z 18 standard 232 Z 18 sleeve 232 Z 18 heavy end bay 232 Z 18 sleeve.All Metsec Z-section product is manufactured from pre-hot dipped galvanised steel, G275 coating and with a minimum yield strength of 450 N/mm2
