Difference between channels, angles ,and square steel

Channel:

Channel is a groove -shaped cross-section of the steel strip .Common channel and sub channel light channel . Hot-rolled channel steel specifications for 5-40 # . After the agreement between the supply of hot alternative channel specifications 6.5-30 # . Channel mainly used for building structure , vehicle manufacturers and other industrial structures , channels and beam often used in conjunction.

iron angle:

Commonly known as angle iron angle , perpendicular to each other on both sides of a triangular strip of steel . There equilateral angle and unequal angle of the points.Models do not represent different sides of the same thickness of size models , which will be in the document contracts angles of edge width, edge thickness dimension fill is complete, to avoid alone model representation . Hot-rolled equilateral angle specifications for the 2 # -20 # .

square cross-section:

Rolled steel or processed into a square cross-section.The density of steel is : 7.851g / cm3Square steel can be divided into two kinds of hot and cold ; hot-rolled square steel side length 5-250mm, cold drawn steel side length 3-100mm.
