槽鋼主要是由唐鋼、包鋼、萊鋼、黃特、馬鋼、寶得、宣鋼、濟(jì)鋼、日鋼等幾家鋼廠生產(chǎn)。 在相同的高度下，輕型槽鋼比普通槽鋼的腿窄、腰薄、

重量輕。18―40號(hào)為大型槽鋼，5―16號(hào)槽鋼為中型槽鋼。進(jìn)口槽鋼標(biāo)明實(shí)際規(guī)格尺寸及相關(guān)標(biāo)準(zhǔn)。槽鋼的交貨長(zhǎng)度分定尺、倍尺二種，并在相應(yīng)的

標(biāo)準(zhǔn)中規(guī)定允差值。國(guó)產(chǎn)槽鋼的長(zhǎng)度選擇范圍根據(jù)規(guī)格號(hào)不同分為5―12m、5―19m、6―19m三種。進(jìn)口槽鋼的長(zhǎng)度選擇范圍一般為6―15m。

The trough steel is mainly produced by Tang steel, Baotou steel, steel, Huang, Maanshan, Baode, Xuande, Jigang, Japanese steel and other steel mills.

At the same height, light trough steel is narrower, waist and lighter than the legs of ordinary slot steel.No.18-40 are large groove steel, and grooves 5-16 are

medium groove steel.Import tank steel indicates the actual specifications and dimensions and relevant standards.The delivery length of slot steel is divided into

fixed rules and double feet, and the allowable value is specified in the corresponding standard.The length selection range of domestic tank steel is divided

into 5-12m, 5-19m and 6-19m according to the specification number.The length selection range of the inlet groove steel is generally 6-15m.
