Steel types & Sizes

About steel sizes

All steel sections are grouped by their section profile. Every profile has different geometrical and strength properties; therefore, their use is dependent on the type of load applied. Steel beams are normally shown on Structural Engineer’s drawings using a thick dashed line with a beam description next to it.

In most cases the steelwork shown is the steelwork at ceiling level for that drawing, e.g., steelwork shown on the first floor is the steelwork above head when standing on the first floor.
