槽钢分普通槽钢和轻型槽钢。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。 槽钢是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。在使用中要求具有较好的焊接、铆接性能及综合机械性能。 生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。 非标槽钢 ，以槽钢的腰高、腿宽、腰厚和每米重量为标准， 非标准的槽钢；主要是为了在不影响安全质量的前提下节省成本，在高、宽、厚上打折扣。例如12#槽钢每米重量12.059kg， 6米为72.354kg，如果一根6米非标12#槽钢为48kg，那么我们称它为下差33.3%（1-48/72.354)。 在我国大部分钢材市场都有销售非标型材，这个就是我们称为减尺。 The groove steel is divided into ordinary groove steel and light groove steel.According to the shape can be divided into four kinds: cold side groove steel, cold bend unequal edge groove steel, cold inner side groove steel, cold outer side groove steel.Slot steel is a groove section of long steel, belongs to the construction and mechanical carbon structure steel, is a complex section of steel steel, its section shape is groove shape.Channel steel is mainly used for building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Good welding, riveting performance and comprehensive mechanical performance are required in use. The raw material billet of the production of tank steel is carbon junction steel or low-alloy steel billet with a carbon content of no more than 0.25%. Non-standard groove steel, with waist height, leg width, waist thickness and weight per meter as standard groove steel; mainly to save cost on height, width and thickness without affecting safety quality.For example, the weight of 12 # tank steel is 12.059kg per meter and 6 meters is 72.354kg. If a 6-meter non-standard 12 # tank steel is 48kg, then we call it the lower difference of 33.3% (1-48 / 72.354).In most of the steel market sales of non-standard profiles, this is what we call the ruler.
