槽钢是由含碳量小于0.25%的碳结构钢或者低合金钢钢坯压制而成，经过热加工成形、正火或者热轧状态成形。 主要用于厂房建筑结构、幕墙工程、机械设备配件和制造车辆钢材。槽钢需要具有较好的焊接性、铆接性和机械性能。 槽钢分热轧槽钢和弯曲槽钢，热轧槽钢又分为普通型和轻型两种；槽钢规格从5号到40号，相应高度为5～40cm； 在相同高度情况下，轻型槽钢比普通槽钢的腿窄、腰薄、重量轻。槽钢用于装饰装修，户外广告牌支架，钢结构板房等较多。 槽钢规格型号是以高度（h）、腿宽（b）、腰厚度（d）等尺寸表示，国产槽钢规格从5-40号，就是表示相对应的高度是5-40cm。 槽钢在相同高度下，轻型槽钢比普通槽钢的腿窄、腰薄、重量轻。18-40号为大型槽钢，5-16号槽钢为中型槽钢。 Tank steel is made of carbon structure steel with carbon content less than 0.25% or low alloy steel billet pressed, formed through hot processing, hot fire or hot rolled state.Mainly used for plant building structure, curtain wall engineering, mechanical equipment accessories and manufacturing of vehicle steel.Tank steel needs to have good soldability, riveting ability and mechanical properties.Channel steel is divided into hot rolled groove steel and bending groove steel, hot rolled groove steel is divided into ordinary type and light two; groove steel specifications from 5 to 40, corresponding height of 5~40cm; at the same height, light trough steel is narrower, thinner waist and lighter than that of ordinary trough steel.Slot steel used for decoration, outdoor billboard support, steel structure board houses and other more.Slot steel specifications are expressed in height (h), leg width (b), waist thickness (d) and other dimensions, domestic trough steel specifications from 5-40, which means that the corresponding height is 5-40cm. Trough steel at the same height, light trough steel than ordinary trough steel narrow legs, thin waist, light weight.No.18-40 is large tank steel, and no. 5-16 tank steel is medium tank steel.
