型鋼是一種有一定截面形狀和尺寸的條型鋼材,是鋼材四大品種(板、管、型、絲)之一。根據斷面形狀，濟南型鋼分簡單斷面型鋼和復雜斷面型鋼（異型鋼）。前者指方鋼、圓鋼、扁鋼、角鋼、六角鋼等；后者指工字鋼、槽鋼、鋼軌、窗框鋼、彎曲型鋼等。但各種型鋼有哪些具體表示方法呢？

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型鋼

H-shaped steel

HW寬翼緣H型鋼，HM中翼緣H型鋼，HN窄翼緣H型鋼。

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

表示方法：H型鋼=h×b×t1×t2

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

h為截面高度

H is the section height

b為截面寬度

B is the section width

t1為腹板厚度

T1 is the web thickness

t2為翼緣厚度

T2 is the flange thickness

例如：H200×180×6×8表示H型鋼的高度為200mm，寬度為180mm，腹板厚度為6mm，翼緣厚度為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.

工字鋼

I-beam

工字鋼也稱為鋼梁,是截面為工字形狀的長條鋼材。工字鋼分普通工字鋼和輕型工字鋼，H型鋼三種。

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.

工字鋼=h×b×d

I-beam=h × b × d

h表示工字鋼的腰高

H represents the waist height of the I-beam

b表示工字鋼的腿寬

B represents the leg width of I-beam

d表示工字鋼的腰厚

D represents the waist thickness of I-beam

例如：160x88x6，即表示腰高為160mm，腿寬為88mm，腰厚為6mm的工字鋼。

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.

工字鋼的規格也可用型號表示，型號表示腰高的厘米數，如腰高160mm的工字鋼表示為工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型鋼

C-shaped steel

C型鋼廣泛用于鋼結構建筑的檁條、墻梁，也可自行組合成輕量型屋架、托架等建筑構件。此外，還可用于機械輕工制造中的柱、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型鋼=h×b×c×t

C-beam=h × b × c × t

h表示C型鋼的截面高度

H represents the section height of C-shaped steel

b表示C型鋼的截面寬度

B represents the section width of C-shaped steel

c表示C型鋼的卷邊寬度

C represents the curling width of C-shaped steel

t表示C型鋼的厚度

T represents the thickness of C-shaped steel

以C80×40x20×2.5為例

C80 × 40x20 × 2.5 as an example

截面高度H=80mm

Section height H=80mm

截面寬度B=40mm

Section width B=40mm

卷邊寬度C=20mm

Curl width C=20mm

厚度t=2.5mm

Thickness t=2.5mm

槽鋼

Channel

槽鋼是截面為凹槽形的長條鋼材，屬建造用和機械用碳素結構鋼，是復雜斷面的型鋼鋼材，其斷面形狀為凹槽形。

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.

槽鋼尺寸表示方法=h×b×tw

Dimension representation of channel steel=h × b × tw

h表示槽鋼腰部的截面高度

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

b表示槽鋼腿部的截面寬度

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

tw表示槽鋼腰部的厚度

Tw represents the thickness of the channel steel waist

例如：100*48*5.3，表示腰高為100毫米，腿寬為48毫米，腰厚為5.3毫米的槽鋼，或稱10#槽鋼。

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.

腰高相同的槽鋼，如有幾種不同的腿寬和腰厚也需在型號右邊加abc予以區別，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.
