槽鋼角鋼沖孔切斷焊接拉彎多種規格異形預埋件

槽鋼的上下腿寬相等，截面呈槽形，槽鋼規格型號的表示方法是以高度（mm）×腿寬（mm）×腰厚（mm）的形式表示。
角鋼是斷面呈直角、兩邊厚度、寬度基本相同的鋼材，角鋼的規格表示方法通常是以邊寬×邊厚來表示。
the upper and lower legs of channel steel are equal in width, and the section is in groove shape. the specification and model of channel steel is expressed in height (mm) × leg width (mm) × waist thickness (mm).
angle steel is steel with right section and basically the same thickness and width on both sides. the specification of angle steel is usually expressed by side width × edge thickness.
