H型鋼屬于經(jīng)濟(jì)裁面型材(其它還有冷彎薄壁型鋼、壓型鋼板等)，由于截面形狀合理，它們能使鋼材更高地發(fā)揮效能，提高承裁能力。

H steel is an efficient and economical cutting section (other cold-formed thin-walled steel and profiled steel sheets). Because of the reasonable shape of the section, they can make the steel play a more effective role and improve the bearing capacity.

型材按使用部門(mén)分類有鐵路用型材（鋼軌、魚(yú)尾板、道岔用軌、車輪、輪箍）、汽車用型材（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。裝飾單板貼面膠合板（裝飾面板、貼面板），是將精密刨切成厚度為0。按斷面尺寸大小分類。

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.
