型材按生产方法可以分成热轧型材、冷弯型材、冷轧型材、冷拔型材、挤压型材、锻压型材、热弯型材、焊接型材和特殊轧制型材等。型材按其横断面形状可分成简单断面型材和复杂断面型材。简单断面型材的横断面对称、外形比较均匀、简单，如圆钢、线材、方钢和扃钢等。Hsteelisanefficientandeconomicalcuttingsection(othercold-formedthin-walledsteelandprofiledsteelsheets)。复杂断面型材又称为异型断面型材，其特征是横断面具有明显凸凹分支。

薄板的宽度为500~1500毫米；厚的宽度为600~3000毫米。薄板按钢种分，有普通钢、优质钢、合金钢、不锈钢、工具钢、耐热钢、轴承钢、硅钢和工业纯铁薄板等。

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.

装饰材料分为两大部分：一部分为室外材料，一部分为室内材料。室内材料再分为石材，板材、片材、型材、线材五个类型。

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.
