Angle and Channels
What is angle/channel?
Angles are commonly used in the construction of buildings, equipments, vehicles and other objects that we use in our everyday lives. They are very cheap and quite reliable for use as supporting structures in construction. Angles are steel structures with L cross section in which the length of the legs could either be equal or unequal and the angle between the legs is 90 degree.
A channel is a hot-rolled mild steel structure that is C-shaped. The structure has a long vertical web and two flanges. Channels can be used both in indoor and outdoor applications. Steel channels are much lighter and flexible than other structures but it usually experiences twisting under certain loading types.
Manufacturing of angle/channel
Angle irons are manufactured using a roll former. A roll former has several rollers and these rollers are used to turn a bar of metal into an angle iron. Using this machine, one is guaranteed a product of the highest quality and of uniform dimensions.
Steel channels are mild steel structures that have been hot-rolled and shaped into having C cross section. Steel channels are usually produced to conform with the grade ASTM A36.
