工字鋼如名所示，是一種“工”字形截面型鋼，上下翼緣內(nèi)表面有傾斜度，一般為1：6，使得翼緣外薄而內(nèi)厚，因此造成工字鋼在兩個主平面的截面特性相差巨大，在應(yīng)用中難以發(fā)揮剛才的強(qiáng)度特性。雖然工字鋼市場上上也出現(xiàn)了加厚工字鋼，但工字鋼的結(jié)構(gòu)已經(jīng)決定了其抗扭性能短板。細(xì)木工板握螺釘力好，強(qiáng)度高，具有質(zhì)堅(jiān)、吸聲、絕熱等特點(diǎn)，而且含水率不高，在10%—13%之間，加工簡便，用途最為廣泛。

I like the name suggests, is a kind of I-shaped section steel flange on the inner surface of slope is generally 1:6, the flange and the thickness of thin, resulting in two main characteristics of I-beam section plane is huge, just to play strength characteristics in the application. Although the I-steel market has also appeared to be thickened I-steel, the structure of I-steel has already determined its torsional performance.

工字鋼的邊長小，高度大，只能承受單方向的力。  H型鋼槽深，厚度大，可以承受兩個方向的力。

工字鋼只能用于橫梁，而H型鋼才能用于結(jié)構(gòu)的承重柱。

The length of the I-steel is small and high. It can only bear the force of the single direction. The H steel groove is deep and thick, and can bear the force of two directi.

I-steel can only be used for crossbeams, and H steel can be used for structure bearing columns.

工字鋼也稱為鋼梁（英文名稱 I Beam)，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。工字鋼廣泛用于各種建筑結(jié)構(gòu)、橋梁、車輛、支架、機(jī)械等。

I-steel beam (also known as English name I Beam), is an H-shaped steel strip section. I-steel is divided into three kinds: ordinary I-steel and light I-steel, H type steel. I-steel is widely used in various architectural structures, bridges, vehicles, stents, machinery and so on.

普通工字鋼和輕型工字鋼的型號是用其腰高厘米數(shù)的阿拉伯?dāng)?shù)字來表示，腹板、翼緣厚度和翼緣寬度不同其規(guī)格以腰高×腿寬(b)×腰厚(d)的毫數(shù)表示，如“普工160×88×6”。

The ordinary beam and light I-beam model is the digital Arabia with its waist high cm number to represent, web and flange thickness and flange width of different specificati to the waist high (H) * (b) * waist leg width thickness (d). The number of said, such as "general 160 x 88 x 6"
