Chapter 45: Structural steel

This chapter concentrates on the specification of hot-rolled and tubular steel structures to BS EN 10025 and BS EN 10210 and their corresponding design standards, BS EN 1993: Eurocode 3 and formerly BS 5950. It also covers other types of steel, such as cold-formed steel to BS EN 10346 and stainless steel to BS EN 10880. The manufacture of steel in terms of metallurgy and process is reviewed which links to the ways of satisfying toughness and weldability criteria. A description of the specification of different modern steel grades is presented and is linked to former standards. Different types of steel sections are presented and their manufacturing process is described. A detailed section on stainless steel reviews the modern steel grades, and particular issues as regards mechanical properties, environmental conditions, connections, etc. Other sections in this chapter provide information on corrosion protection, fire protection and site installation, which are important aspects of steel construction.
