The model and grade of American standard H-beam American standard H-beam steel is a steel widely used in the field of construction, bridge and machinery manufacturing, and its model and grade are also relatively special. Below we will introduce the models and grades of American standard H-beams in detail.
The model of American standard H-beam is mainly composed of four parts: H height, B width, TT web thickness, and flange thickness. Depending on the model, the height range of H-beams is between 100mm and 500mm, the width range is between 150mm and 300mm, the web thickness range is between 7mm and 30mm, and the flange thickness range is between 12mm and 50mm.
The grade of American Standard H-beam mainly contains the manufacturer's logo, steel quality, use, heat treatment status and other information. For example, the grade of an American standard H-beam is "A123", where "A" indicates that the steel is produced by Manufacturer A, and "123" indicates the model of the steel.
American standard H-beams also have different quality grades, such as A, B, C, D four grades. Different grades of steel have slight differences in mechanical properties and chemical composition to meet different use needs.
The type and grade of American Standard H-beam are the basis for the correct selection and use of this steel. In practical application, it is necessary to select the appropriate model and quality level according to the specific use environment and requirements to ensure the safety and reliability of the project.
