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。TheflangeoftheHsteelisequalthickness,hasarollingcrosssection,andasectionof3plates。 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#。

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#.

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。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。按斷面尺寸大小分類(lèi)。

薄板的寬度為500~1500毫米；厚的寬度為600~3000毫米。薄板按鋼種分，有普通鋼、鋼、合金鋼、不銹鋼、工具鋼、耐熱鋼、軸承鋼、硅鋼和工業(yè)純鐵薄板等。

The width of the thin plate is 500~1500 mm, and the thickness is 600~3000 mm. The sheet is divided by steel, including ordinary steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat resistant steel, bearing steel, silicon steel and industrial pure iron sheet.

裝飾材料分為兩大部分：一部分為室外材料，一部分為室內(nèi)材料。室內(nèi)材料再分為石材，板材、片材、型材、線材五個(gè)類(lèi)型。

Decorative materials are divided into two parts: one is outdoor materials, the other is indoor materials. Indoor materials are further divided into five types: stone, sheet, sheet, profile and wire.
