槽钢即截面为凹槽形的长条钢材，属建造用和机械用碳素结构钢，是复杂断面的型钢钢材，其断面形状为凹槽形。 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a、b、c予以区别，如25#a 25#b 25#c等。 槽钢分普通槽钢和轻型槽钢。热轧普通槽钢的规格为5-40#。经供需双方协议供应的热轧变通槽钢规格为6.5-30#。 槽钢主要用于建筑结构、车辆制造、其它工业结构和固定盘柜等，槽钢还常常和工字钢配合使用。 槽钢按形状又可分为4种：冷弯等边槽钢、冷弯不等边槽钢、冷弯内卷边槽钢、冷弯外卷边槽钢。依照钢结构的理论来说， 应该是槽钢翼板受力，就是说槽钢应该立着，而不是趴着。 槽钢的规格主要用高度（h）、腿宽（b）、腰厚度（d）等尺寸来表示，国产槽钢规格从5 -40 号，即相应的高度为5 -40cm 。 Slot steel is a long groove-shaped steel, which is a carbon structure steel for construction and machinery. It is a type steel with complex section, and its section shape is groove shape.Slot steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.It is required to have good welding, riveting performance and comprehensive mechanical performance in use. The raw material billet of producing trough steel is carbon junction steel or low alloy billet with a carbon content of not more than 0.25%. Finished tank steel is delivered by hot processing, hot or hot rolled state. Its specifications are indicated by waist height (h) * leg width (b) * waist thickness (d) mm, such as 100 * 48 * 5.3, indicating that waist height is 100 mm, leg width is 48 mm, waist thickness of 5.3 mm slot steel, or 10 # slot steel. Channel steel with the same waist height, if there are several different leg width and waist thickness, you also need to add a, b, c on the right side of the model, such as 25 # a 25 # b 25 # c, etc.The trough steel is divided into ordinary groove steel and light trough steel. The specification of hot rolled ordinary groove steel is 5-40 #. The specification of hot rolled flexible tank steel supplied by supply and demand is 6.5-30 #.Channel steel is mainly used for building structure, vehicle manufacturing, other industrial structures and fixed plate cabinets, etc., groove steel is often used with I-word steel. Slot steel can be divided into four kinds according to the shape: cold bent equal edge groove steel, cold bending unequal edge groove steel, cold bend inner coil edge groove steel, cold bend outer coil edge groove steel.According to the theory of steel structure, it should be the trough steel wing plate force, that is, the trough steel should stand, rather than lying prone. The specifications of groove steel are mainly indicated by height (h), leg width (b) and waist thickness (d). The specifications of domestic groove steel range from 5-40, that is, the corresponding height is 5-40cm.
