What is PFC in structural steel?

What is PFC in structural steel?

The PFC steel beam is commonly referred to as a steel channel as the profile matches this description. The abbreviated PFC stands for Parallel Flange Channel. PFC beams are readily available for use across all sectors of industry including mining, residential and commercial construction.

What is hollow tubular sections?

Hollow Section is a type of metal profile with a hollow tubular cross section. HSS is only composed of structural steel per code. During the manufacturing process flat steel plate is gradually changed in shape to become round where the edges are presented ready to weld.

What is hollow tube?

A hollow tube is mounted on the burner and the light path passes along the length of the tube. Samples are nebulized and atoms enter the tube where they are prevented from dispersing throughout and beyond the flame by the physical presence of the tube.

How are hollow sections of a tube formed?

Rectangular/ Square hollow section are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape. Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.

How are hollow structural sections ( HSS ) made?

The transformation of steel strip into hollow structural sections (HSS) is the result of a series of operations including formi ng, welding and sizing. Currently three methods are being used in North America for the manufacture of HSS.
