槽鋼按形狀又可分為4種：冷彎等邊槽鋼、冷彎不等邊槽鋼、冷彎內(nèi)卷邊槽鋼、冷彎外卷邊

依照鋼結(jié)構(gòu)的理論來說，應(yīng)該是槽鋼翼板受力，就是說槽鋼應(yīng)該立著槽鋼，普通槽鋼規(guī)格而不是趴著。

According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled steel, cold bending edge edge

According to the theory of steel structure, it should be the force of the channel steel wing plate, that is to say the channel steel should stand the channel steel, ordinary channel steel specification rather than lie.

型材按斷面尺寸可分為大型、中型和小型型材，其劃分常以它們分別適合在大型、中型和小型軋機上軋制來分類。大型、中型和小型的區(qū)分實際上并不嚴格。另外還有用單重（kg/m）來區(qū)分的方法。一般認為，單重在5 kg/m以下的是小型材，單重在5～20 kg/m的是中型材，單重超過20 kg/m的是大型材。因此又可以進一步分成凸緣型材、多臺階型材、寬薄型材、局部特殊加工型材、不規(guī)則曲線型材、復(fù)合型材、周期斷面型材和金屬絲材等等。Becauseofthereasonableshapeofthesection,theycanmakethesteelplayamoreeffectiveroleandimprovethebearingcapacity。

按專業(yè)用途分，有油桶用板、搪瓷用板、彈板用板等；按表面涂鍍層分，有鍍鋅薄板、鍍錫薄板、鍍鉛薄板、塑料復(fù)合鋼板等。

According to professional use, there are oil  board, enamel plate, bulletproof plate and so on. According to surface coating, there are galvanized sheet, tin plate, leaded sheet, plastic  steel plate and so on.

細木工板握螺釘力好，強度高，具有質(zhì)堅、吸聲、絕熱等特點，而且含水率不高，在10%—13%之間，加工簡便，用途為廣泛。

The woodworking board has good grip strength, high strength, strong quality, sound absorption, insulation and other characteristics, and water content is not , between 10% - 13%, easy processing, the most widely used.
