THE COMPONENTS OF STEEL STRUCTURE

There are several components of steel structure which can be divided in two general types ; Main Frame & Connectors.

Main Frame ==> Beams, columns, girders, hollow section structural, bar, etc.

Wide Flange Beam(also known as W-Shape)

Connectors ==> Structural tee, angle, channel, plates, etc.


Structural Tee

Usually used as a connectors..but also can be used as tee beam or floor.


Channel (C-Shape)

Angle (L-Shape)
