What are rolled structural steel sections?

The steel sections manufactured in rolling mills and used as structural members are known as rolled structural steel sections. The steel sections are named according to their cross sectional shapes.

What are the most commonly used rolled steel sections?

∴ The rolled steel I – sections are most commonly used as beams because these provide a large moment of inertia with the less cross-sectional area and greater lateral stability.

What are rolled sections?

What is a rolled beam?

Plate girder and rolled beam (also known as wide flange shapes) are common superstructure elements for short span steel bridges. A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape.

Why are built-up sections used?

The built-up beams are used when the span, load and corresponding bending moment are of such magnitudes that rolled steel beam section becomes inadequate to provide required section modulus. Built-up beams are also used when rolled steel beams are inadequate for limited depth.

Which is the Free Library for steel sections?
