A kind of strip steel bearing the section with two orthogonal side. It is divided into equal angle and unequal angle. The kind which has two equal upright border is equal angle, otherwise, if one border is longer and another is shorter, that is called unequal angle. Its specification can be described by border width * border width * border thickness (mm).
20-120#
H beam is developed and optimized from I beam, a kind of economical profiled steel with a better mechanics capabilities. The web plates and the flanges are in plumb.
large-scale building requiring large carrying capacity and good stability (e.g. high-rise building, workshop etc.), bridge, shipbuilding, crane, machinery foundation, trestle and foundation pile.
Channel is a kind of strip steel with a flute section. There is an instance for its size description now: 120*53*5, means the height of its waist is 120mm, the width of legs is 53mm and the thickness of waist is 5mm, or we can call it 12# channel. When there are kinds of channel with the same height of waist but different width of legs and thickness of waist, they must be differentiated by a b c, which is added to the right of the type no. Such as 25a# 25b# 25c# and so on.
Hot rolled round steel with d 5.5mm-d 14mm or deformed steel with less than 10mm diameter.
