冷弯异型钢本色黑槽钢钢结构屋面檩条碳钢U型槽钢货新无锈
槽钢承受垂直荷重的能力与其垂直方向有效截面成正比，所以将其开口朝左或朝右放置，能够承受的垂直荷重最大。槽钢有三个方向可放，即：立放、仰放、趴放，有N种支撑方式：两端简支、两端固定、悬臂、一端悬臂另一端简支、两端悬臂等等。通常有两种材料选择：Q235、Q345。即使支撑方式和材料的选择不同，也还是将其开口朝左或朝右放置，能够承受的垂直荷重最大。槽钢的规格设定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。18-40号为大型槽钢，5-16号槽钢为中型槽钢。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。The capacity of the slot steel to withstand the vertical load is proportional to its vertical effective section, so place its opening left or right to bear the maximum vertical load.Slot steel has three directions can be put, namely: vertical, back, prone, with N kinds of support: both ends of simple support, both ends fixed, cantilever, one end of the other end of simple support, both ends of the cantilever and so on.There are usually two kinds of materials selected: Q235, Q345. Even if the support mode is different from the choice of the material, they still place the opening to either left or right, bearing the maximum vertical load.Specifications of groove steel The specifications of groove steel are mainly indicated by height (h), leg width (b), waist thickness (d) and other dimensions. The specifications of domestic groove steel range from 5-40, that is, the corresponding height is 5-40cm.grooves 18-40 are large trough steel and grooves 5-16 are medium groove 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.Slot steel is carbon structural steel for construction and machinery. It is a steel steel of complex section. Its section shape is groove.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.发票说明：当前价格不含税，开票另加税点，详细咨询客服！
