Part 1: Architect’s Guide 1 - 10 3.2.1 Hot rolled long products Hot rolled long products (often referred to as ‘sections’ or ‘profiles’) are generally used for the main frame members (columns, beams, bracings).

In this way, cellular beams (Figure 3.3) can be fabricated from IPE or HE sections by oxy-cutting and welding.
