Structural steel

A structural steel is a category of steel used to manufacture building materials in a variety of forms. Giving architects and civil engineers freedom in design.

The history of steel constructions begins in the 20th century. During the Second World War, steel became available at affordable prices, causing many contractors to choose it as a viable way to build.

The shapes, dimensions, chemical composition, mechanical properties of a structural steel are regulated by standards in most industrialized countries.

The steel used to make the metal constructions is part of the mild steel category with low carbon content.

Depending on the values ​​of the mechanical characteristics and the chemical composition, there are several brands for general purpose steels.

When choosing construction steels, the norms of the EN 10025 standard from 1-6 will be used, where:

1. establishes general delivery conditions.

2. establishes Technical Delivery Conditions for non-alloyed structural steels

3. establishes Technical Delivery Conditions for normalized fine-grained steels/weldable rolled steels.

4. establishes technical delivery conditions for thermomechanically rolled fine-grained steels.

5. establishes Technical Delivery Conditions for steels resistant to atmospheric corrosion.

6. establishes the technical delivery conditions for high yield strength steel plates.

While many sections are formed by hot or cold rolling, others are made by welding or bending steel sheets.

STRUCTURAL STEEL – THE MOST COMMON FORMS USED:

• U profiles;
• europrofile Inp, Ipe, Hea, Heb, Hem;
• corners;
• T profiles;
• pipes;
• boards and platbands;
• round and square bars.

Steel constructions are growing in popularity throughout the world, with every region benefiting from steel over the years. Many of the best architectural wonders have been built using steel.

One of the most important characteristics of steel is its ductility, which differs depending on the quality (brand) of the material, being reduced in the case of high-strength steels. The decrease in ductility makes the structural steel more sensitive to the presence of residual stresses and increases the risk of brittle breaks.

The appropriate choice of the quality of the structural steel is a particularly important issue from the point of view of ensuring the safety in operation of a metal construction, with the aim of avoiding the phenomenon of lamellar disintegration of the steel.
