型材是鐵或鋼以及具有一定強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。型材既能單獨使用也能進一步加工成其他制造品,常用于建筑結(jié)構(gòu)與制造安裝。一般認(rèn)為,單重在5kg/m以下的是小型材,單重在5~20kg/m的是中型材,單重超過20kg/m的是大型材。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)。軋機結(jié)構(gòu)和軋機布置形式較多。在結(jié)構(gòu)形式上有二輥式軋機、三輥式軋機、孔型軋機、多輥孔型軋機、Y型軋機、45°軋機和懸臂式軋機等。
板材是指一般的壓型鋼板平板等,都是較薄的鋼板,通常都作為屋面或圍護墻等用型材是指熱軋的冷彎的如工字鋼H鋼C型鋼Z型鋼,通常都作主結(jié)構(gòu)用。
Plate refers to the general profiled steel plate, flat plate, etc., which are thin steel plates, usually used as roofing or retaining walls.
Profiles refer to hot rolled cold-formed ones, such as I-steel, H steel, C steel and Z section steel, which are usually used for main structure.
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.
