工字鋼：工字鋼鋼質(zhì)型材的一種，也稱(chēng)鋼梁，是截面為工字形的長(zhǎng)條鋼材--由此得名“工字鋼”。 工字鋼 規(guī)格及型號(hào) 其規(guī)格以腰高的毫數(shù)表示，如“工160×88×6”，即表示腰高為160毫米，腿寬為88毫米，腰厚為6毫米的工字鋼。 標(biāo)稱(chēng)規(guī)格 工字鋼的規(guī)格也可用型號(hào)表示，型號(hào)表示腰高的厘米數(shù)，如工16#。型材按生產(chǎn)方法可以分成熱軋型材、冷彎型材、冷軋型材、冷拔型材、擠壓型材、鍛壓型材、熱彎型材、焊接型材和特殊軋制型材等。

I-steel: a steel bar of I-steel, also known as steel beam, is a long steel section of the cross section, which is called "i-i-steel". The specificati and types of I-steel are represented by the number of waist height, such as "160 x 88 x 6", that is, I-bar with waist height of 160 mm, leg width of 88 mm and waist thickness of 6 mm. The specificati of the nominal size of the I-steel can also be expressed by the model, and the size of the height of the waist is centimetre, such as the 16#.

槽鋼分普通槽鋼和輕型槽鋼。熱軋普通槽鋼的規(guī)格為5-40#。經(jīng)供需雙方協(xié)議供應(yīng)的熱軋變通槽鋼規(guī)格為6.5-30#。槽鋼主要用于建筑結(jié)構(gòu)、車(chē)輛制造、其它工業(yè)結(jié)構(gòu)和固定盤(pán)柜等，槽鋼還常常和工字鋼配合使用。

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled ordinary channel steel is 5-40#. The specification of hot rolled and variable channel steel supplied by both suppliers and suppliers is 6.5-30#. Channel steel is mainly used in building structure, vehicle manufacturing, other industrial structure and fixed disk cabinet, and channel steel is often used in conjunction with I-steel.

型材按使用部門(mén)分類(lèi)有鐵路用型材（鋼軌、魚(yú)尾板、道岔用軌、車(chē)輪、輪箍）、汽車(chē)用型材（輪輞、輪胎擋圈和鎖圈）、造船用型材（L型鋼、球扁鋼、Z字鋼、船用窗框鋼）、結(jié)構(gòu)和建筑用型材（H型鋼、工字鋼、槽鋼、角鋼、吊車(chē)鋼軌、窗框和門(mén)框用材、鋼板樁等）、礦山用鋼（U型鋼、槽幫鋼、礦用工字鋼、刮板鋼等）、機(jī)械制造用異型材等。按斷面尺寸大小分類(lèi)。挑選時(shí)，膠合板要木紋清晰，正面光潔平滑，不毛糙，要平整無(wú)滯手感。
