European standard I-beam, also known as European standard I-beam, is a steel widely used in construction, bridges, machinery and other fields. There are certain standards and specifications for the specification and size representation method, and the specification and size representation method of the European standard I-beam will be introduced in detail below.
First, the basic parameters of the European standard I-beam.
The basic parameters of the European standard I-beam include cross-section height (h), flange width (b), web thickness (t1) and flange thickness (t2). These parameters determine the load-bearing capacity and range of use of the I-beam. Among them, the cross-sectional height h is one of the important parameters, which determines the overall size and bearing capacity of the I-beam.
Second, the European standard I-beam representation method.
The specification and size representation method of European standard I-beam is generally expressed by a combination of letters and numbers. The specific representation is as follows:
1.Representation of cross-sectional height h: The cross-sectional height h is expressed in millimeters (mm) and is expressed as a number. For example, h=200 means that the cross-section height is 200 mm.
2.Representation of flange width b: Flange width b is also expressed in millimeters and is expressed as a number. For example, b=100 means that the flange width is 100 mm.
3.Representation of web thickness t1: Web thickness t1 is expressed in millimeters and is expressed as a number. For example, t1=8 means that the web thickness is 8 mm.
4.Representation of flange thickness t2: Flange thickness t2 is also expressed in millimeters and is expressed as a number. For example, t2=12 means that the flange thickness is 12 mm.
Combining these parameters, it is possible to form a complete European standard I-beam specification and size representation method. For example, IPB 200x100x8x12 represents a Euro standard I-beam with a cross-section height of 200 mm, a flange width of 100 mm, a web thickness of 8 mm, and a flange thickness of 12 mm.
