Figure 5.3 Hot-rolled structural steel sections.
A range of comparatively small section ‘joists’ are also available, which have shallowly
tapered flanges and are produced for use as beams for small to medium spans. The series
of structural T’s is produced from cuts that are half the web depth of standard universal
beams and columns. The range of standard hot-rolled structural steel angles and channels
has tapered flanges. The standard rolled steel sections are usually supplied in strength grade
43A material with strength grades 50 and 55 available for all sections at an additional cost
per tonne. All of the standard sections are available in Cor-Ten B weathering steel.
