槽钢剪刃设计的基本依据是槽钢成品孔型形状，如图1所示(以100#槽钢为例)。这种设计在剪切过程中易出现以下问题：一是槽钢两肩部与其他部分相比，相对较厚，所需剪切力也较大，剪刃磨损较快，剪刃使用一段时间后。这一部分相对磨损量大，致使肩部间隙较大，易出现塌肩现象；二是槽钢两腿与腰部处相比，由于剪切角度的影响，当剪刃磨损后，在剪切两腿时，剪切量变小，腿部剪切由通常的剪断变成了撕断，槽钢腿端面极易出现毛刺；三是上、下剪刃腿部斜度与槽钢成品孔型基本一致，这样在剪切时腿部基本同时受力，剪切力较大，剪刃磨损较快，一方面腿端剪切压痕严重，另一方面剪刃老化后，极易出现槽钢剪切部分撕裂、毛刺较多的现象。后两点是影响槽钢剪切质量的主要原因。
槽钢的表面质量及几何形状的允许偏差在标准中有具体规定。一般要求表面不得存在用上有害的缺陷，不得有显着的扭转，规定槽钢波浪弯（镰刀弯）的允许值及各规格槽钢面形状的有关参数（h ，b ，d ，t 等）的数值、允差值。槽钢几何形状不正确的主要表现是：角、腿扩及腿并等。
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。
