彎曲度：工字鋼高度小于或等于400MM時，每米彎曲度不得大于1.5MM，總彎曲度不得大于總長度的0.15%。高度大于400MM時，每米彎曲度不得大于1.0MM，總彎曲度不得大于總長度的0.1%。

Bending degree: when the height of the I-steel is less than or equal to 400MM, the bending degree of each meter must not be more than 1.5MM, and the total bending degree should not be more than 0.15% of the total length. When the height is greater than 400MM, the bending degree of each meter must not be more than 1.0MM, and the total bending degree should not be more than 0.1% of the total length.

H型鋼，是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面型材，因其斷面與英文字母“H”相同而得名。H型鋼的兩條外邊內(nèi)側(cè)沒有斜度，是平直的。這使得H型鋼的焊接拼接比工字鋼操作簡單，單位重量的力學(xué)性能更好，可以節(jié)省大量的材料和施工時間。

H steel is a more efficient and economical section with high section area distribution, because its section is the same as the English letter "H". The two sides of the H type steel have no slope inside the inner side, and they are straight. This makes the welding and splicing of H steel simpler than I-steel, better mechanical properties per unit weight, and can save a lot of material and ctruction time.

型材是鐵或鋼以及具有一定強(qiáng)度和韌性的材料通過軋制、擠出、鑄造等工藝制成的具有一定幾何形狀的物體。這類材料具有的外觀尺寸一定，斷面呈一定形狀，具有一定的力學(xué)物理性能。Ｈ型鋼的軋制不同于普通工字鋼僅用一套水平軋輥，由于其翼緣較寬且無斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時進(jìn)行輥軋。型材既能單獨(dú)使用也能進(jìn)一步加工成其他制造品，常用于建筑結(jié)構(gòu)與制造安裝。型材的材質(zhì)、規(guī)格尺寸等可參照相應(yīng)的國家標(biāo)準(zhǔn)。軋機(jī)結(jié)構(gòu)和軋機(jī)布置形式較多。在結(jié)構(gòu)形式上有二輥式軋機(jī)、三輥式軋機(jī)、孔型軋機(jī)、多輥孔型軋機(jī)、Y型軋機(jī)、45°軋機(jī)和懸臂式軋機(jī)等。
