Section reference

The section reference of a M-section 232mm deep and 1.8mm thick = 232 M 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 (i.e. M for M-section). The last two digits indicate the material thickness (i.e. 18 equals 1.8mm).
