Is 'structural steel' the same as 'rebar'?

No. Structural steel refers to shaped members (I-beams, columns) that form the main framework. Rebar (reinforcing bar) is steel rod used inside concrete to give it tensile strength.

Can 'structural steel' be plural?

It is generally an uncountable/mass noun (like 'concrete' or 'wood'). You refer to quantities of it (tonnes of structural steel) or specific pieces (structural steel beams). You would not say 'structural steels'.

What are common shapes for structural steel?

Common shapes include I-beams (universal beams), H-sections, channels, angles, tees, and hollow structural sections (HSS) like square and rectangular tubing.
