Structure

Columns

These are upright posts made of steel to which beams are bolted. They can be supported with bracing to improve the structure's rigidity.

Beams

Beams are the sections of steel that run across the top of the columns. They can be any length and are securely bolted to the columns.

Joists

These run at right angles to the beams and support the decking. They sit on top of the beams or can be located between the beam webs to reduce the floor's depth. Joists vary in length depending on the use of the floor.

Decking

Decking is the surface of the floor and is laid on the beams. It can be made from chipboard or steel.
