型钢是一种有一定截面形状和尺寸的条型钢材,是钢材四大品种(板、管、型、丝)之一。根据断面形状，济南型钢分简单断面型钢和复杂断面型钢（异型钢）。前者指方钢、圆钢、扁钢、角钢、六角钢等；后者指工字钢、槽钢、钢轨、窗框钢、弯曲型钢等。但各种型钢有哪些具体表示方法呢？

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?

H型钢

H-shaped steel

HW宽翼缘H型钢，HM中翼缘H型钢，HN窄翼缘H型钢。

HW wide flange H-shaped steel, HM medium flange H-shaped steel, HN narrow flange H-shaped steel.

表示方法：H型钢=h×b×t1×t2

Expression method: H-shaped steel=h × b × t1 × t2

h为截面高度

H is the section height

b为截面宽度

B is the section width

t1为腹板厚度

T1 is the web thickness

t2为翼缘厚度

T2 is the flange thickness

例如：H200×180×6×8表示H型钢的高度为200mm，宽度为180mm，腹板厚度为6mm，翼缘厚度为8mm。

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.

工字钢

I-beam

工字钢也称为钢梁,是截面为工字形状的长条钢材。工字钢分普通工字钢和轻型工字钢，H型钢三种。

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.

工字钢=h×b×d

I-beam=h × b × d

h表示工字钢的腰高

H represents the waist height of the I-beam

b表示工字钢的腿宽

B represents the leg width of I-beam

d表示工字钢的腰厚

D represents the waist thickness of I-beam

例如：160x88x6，即表示腰高为160mm，腿宽为88mm，腰厚为6mm的工字钢。

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.

工字钢的规格也可用型号表示，型号表示腰高的厘米数，如腰高160mm的工字钢表示为工16#。

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型钢

C-shaped steel

C型钢广泛用于钢结构建筑的檩条、墙梁，也可自行组合成轻量型屋架、托架等建筑构件。此外，还可用于机械轻工制造中的柱、梁和臂等。

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型钢=h×b×c×t

C-beam=h × b × c × t

h表示C型钢的截面高度

H represents the section height of C-shaped steel

b表示C型钢的截面宽度

B represents the section width of C-shaped steel

c表示C型钢的卷边宽度

C represents the curling width of C-shaped steel

t表示C型钢的厚度

T represents the thickness of C-shaped steel

以C80×40x20×2.5为例

C80 × 40x20 × 2.5 as an example

截面高度H=80mm

Section height H=80mm

截面宽度B=40mm

Section width B=40mm

卷边宽度C=20mm

Curl width C=20mm

厚度t=2.5mm

Thickness t=2.5mm

槽钢

Channel

槽钢是截面为凹槽形的长条钢材，属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为凹槽形。

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.

槽钢尺寸表示方法=h×b×tw

Dimension representation of channel steel=h × b × tw

h表示槽钢腰部的截面高度

H represents the cross-sectional height of the channel steel waist

b表示槽钢腿部的截面宽度

B represents the cross-sectional width of the channel steel leg

tw表示槽钢腰部的厚度

Tw represents the thickness of the channel steel waist

例如：100*48*5.3，表示腰高为100毫米，腿宽为48毫米，腰厚为5.3毫米的槽钢，或称10#槽钢。

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.

腰高相同的槽钢，如有几种不同的腿宽和腰厚也需在型号右边加abc予以区别，如25#a25#b25#c等。

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.
