槽钢是截面为凹槽形的长条状钢材。槽钢属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为槽形。槽钢主要用于建筑结构、幕墙工程、机械设备和车辆制造等。在使用中要求其具有较好的焊接、铆接性能及综合机械性能。产槽钢的原料钢坯为含碳量不超过0.25%的碳结钢或低合金钢钢坯。成品槽钢经热加工成形、正火或热轧状态交货。其规格以腰高(h)*腿宽(b)*腰厚(d)的毫米数表示，如100*48*5.3，表示腰高为100毫米，腿宽为48毫米，腰厚为5.3毫米的槽钢，或称10#槽钢。腰高相同的槽钢，如有几种不同的腿宽和腰厚也需在型号右边加abc予以区别
Channel steel is a long strip of steel with a groove shaped section. Channel steel is a carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. Channel steel is mainly used for building structure, curtain wall engineering, machinery and equipment and vehicle manufacturing. It is required that it has better welding, riveting properties and comprehensive mechanical properties. The raw material billet for producing channel steel is carbon steel or low alloy steel billet with carbon content less than 0.25%. The finished channel steel is delivered by hot working, normalizing or hot rolling. Its specifications are expressed in millimeters of waist height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, representing 100 millimeter waist height, 48 millimeter leg width, 5.3 millimeter channel steel with waist thickness, or 10# channel steel. If the same height of the channel steel, if there are several different leg width and waist thickness, it is also necessary to add the ABC on the right side of the model.
