型材英语怎么说

型材英文单词是 "profiles" 或 "structural steel profiles"，这两个词都可以用来描述钢材或其他材料制成的长条形材料。型材通常用于建筑结构或机械部件，因为它们可以承受大的荷载。

型材这个词来源于拉丁文 "profile"，它的意思是 "形状" 或 "轮廓"。在英语中，这个词经常用来描述一个物体的整体外观，也可以指一个人的典型特征或角色。

下面是一些例句：

The building is made of steel profiles and reinforced concrete.

The profiles of the machine parts were carefully calculated to ensure they could withstand the forces acting on them.
