一、型钢的分类

1、 Classification of steel profiles

型钢是按照其截面形状分类的，根据形状的不同，型钢可以分为多种类型，常见的有以下几种：

Section steel is classified according to its cross-sectional shape. Depending on the shape, section steel can be divided into various types, with the following common ones:

1. 方钢：截面呈正方形，一般用于建筑中的桥梁、设备、机械等领域。

1. Square steel: with a square cross-section, it is generally used in the fields of bridges, equipment, machinery, etc. in construction.

2. 圆钢：截面呈圆形，用途非常广泛，包括建筑中的楼梯扶手、栏杆，汽车制造、船舶建造等领域。

2. Round steel: With a circular cross-section, it has a wide range of applications, including staircase handrails and railings in buildings, automotive manufacturing, shipbuilding, and other fields.

3. H 型钢：截面呈 H 形，具有较高的强度，广泛用于建筑和机械设备领域。

3. H-shaped steel: It has an H-shaped cross-section and high strength, and is widely used in the fields of construction and mechanical equipment.

4. I 型钢：截面呈 I 形，一般用于建筑中的桥梁、高层建筑的结构支撑等。

4. I-shaped steel: It has an I-shaped cross-section and is generally used for structural support of bridges and high-rise buildings in buildings.

5. 角钢：截面呈 L 形，经常被用作建筑和机械领域中的支撑构件。

5. Angle steel: with an L-shaped cross-section, it is often used as a supporting component in the fields of construction and machinery.
