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、幕墙工程、机械设备、车辆制造、固定盘柜和其它工业结构，槽钢还经常和工字钢配合使用。 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。这两种都属型材，是管架常用材料。仅截面形状不同， 选用原则略有差异，由于惯性距的因素以及相当截面面积的工字钢比槽钢的平面外稳定性较好， 通常受压构件或者需考虑平面外变形的多选用H钢或工字钢，但是工字钢的加工、节点做法比槽钢复杂， 所以在结构受力不复杂或者杆件应力不大的情况下，可以采用槽钢。具体选定应由设计方通过方案对照的应力计算确定。 其实用途大部分场合可以通用，在纯弯矩、轴线两边受力相对均衡时工字钢比较适合，稳定性较好。 在边缘加固且要求表面美观时，那么选择槽钢就比较合适。 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, curtain wall engineering, mechanical equipment, vehicle manufacturing, fixed plate cabinets and other industrial structures, groove steel is often used with I-word steel.It is required to have good welding, riveting performance and comprehensive mechanical performance in use.Both of them are profiles and are commonly used for pipe racks. Only section shape is different, the principle is slightly different, due to inertial distance factors and considerable section area of I word steel than groove steel plane stability is better, usually compression components or need to consider plane deformation of H steel or I word steel, but I word steel processing, node is complex than groove steel, so in the case of structure is not complex or rod stress, groove steel can be used. The specific selection shall be determined by the designer.In fact, the use can be used on most occasions, in the pure bending moment, the axis on both sides of the force is relatively balanced when the I-word steel is more suitable, the stability is better. When the edge is reinforced and the surface is beautiful, then the choice of groove steel is more appropriate.
