Section steel is a kind of strip steel with a certain cross-sectional shape and size, which is one of the four major types of steel (plate, tube, profile, and wire). According to the section shape, Jinan section steel is divided into simple section steel and complex section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc; The latter refers to I-shaped steel, channel steel, steel rails, window frame steel, curved section steel, etc. But what are the specific representations of various steel sections?
HW wide flange H-shaped steel, HM medium flange H-shaped steel, HN narrow flange H-shaped steel.
Expression method: H-shaped steel=h × b × t1 × t2
H is the section height
B is the section width
T1 is the web thickness
T2 is the flange thickness
Example: H200 × one hundred and eighty × six × 8 indicates that the height of H-shaped steel is 200mm, the width is 180mm, the thickness of the web is 6mm, and the thickness of the flange is 8mm.
I-beam, also known as a steel beam, is a long strip of steel with an I-shaped cross-section. There are three types of I-beam: ordinary I-beam, light I-beam, and H-beam.
I-beam=h × b × d
H represents the waist height of the I-beam
B represents the leg width of I-beam
D represents the waist thickness of I-beam
For example, 160x88x6 refers to an I-beam with a waist height of 160mm, a leg width of 88mm, and a waist thickness of 6mm.
The specification of I-beam can also be represented by model, which indicates the number of centimeters of waist height. For example, I-beam with a waist height of 160mm is represented as I-16 #.
C-shaped steel is widely used in purlins and wall beams of steel structures, and can also be self assembled into lightweight roof trusses, brackets, and other building components. In addition, it can also be used for columns, beams, and arms in mechanical light industry manufacturing.
C-beam=h × b × c × t
H represents the section height of C-shaped steel
B represents the section width of C-shaped steel
C represents the curling width of C-shaped steel
T represents the thickness of C-shaped steel
C80 × 40x20 × 2.5 as an example
Section height H=80mm
Section width B=40mm
Curl width C=20mm
Channel steel is a long strip steel with a groove shaped section, belonging to carbon structural steel for construction and machinery. It is a complex section steel with a groove shaped section.
Dimension representation of channel steel=h × b × tw
H represents the cross-sectional height of the channel steel waist
B represents the cross-sectional width of the channel steel leg
Tw represents the thickness of the channel steel waist
For example, 100 * 48 * 5.3 represents a channel steel with a waist height of 100 mm, a leg width of 48 mm, and a waist thickness of 5.3 mm, or 10 # channel steel.
For channel steels with the same waist height, if there are several different leg widths and waist thicknesses, it is also necessary to add abc to the right of the model to distinguish them, such as 25 # a25 # b25 # c.
