Profile standard for European standard H-beams.
With the continuous development of industry, European standard H-beam has been widely used in various fields as an important construction and engineering material. In order to ensure its quality and safety, the profile standards of European standard H-beams are also increasingly valued. This article will introduce the profile standards of European standard H-beam in detail, in order to provide reference for the development of related industries.
1. Definition and classification of European standard H-beam.
European standard H-beam is a kind of steel with an H-shaped cross-section, which is mainly used in construction, bridges, machinery manufacturing and other fields. According to different standards, European standard H-beam can be divided into different types. Among them, the common classification methods are: by size, use, material, etc.
Second, the European standard H-beam profile standard.
1.Size standard.
The size standards of European standard H-beams are mainly based on the European standards EN 10034 and EN 10064. These standards specify the allowable deviations and tolerance ranges of parameters such as cross-sectional dimensions, lengths, widths, heights, etc. of H-beams. In addition, the weight and allowable deviation of different specifications of H-beam are also specified.
2.Material standards.
The material of European standard H-beam is generally made of low-alloy high-strength structural steel, which has high yield strength and tensile strength and good mechanical properties. The European standard EN 10025 specifies the specific chemical composition, mechanical properties and test methods of this type of steel.
3.Surface quality standards.
The surface quality of European standard H-beams has an important impact on its service life and safety. The European standard EN 10113 specifies the permissible limits for surface quality and defects in H-beams. This standard requires that the surface of H-beam should be flat and smooth, without obvious defects such as cracks and bubbles.
4.Anti-corrosion and fire protection standards.
European standard H-beams may face various corrosion and fire risks during use. The European standards EN 12068 and EN 13634 specify the requirements for anti-corrosion and fire-retardant coatings for H-beams, respectively. These standards require detailed provisions on the performance, coating process and coating thickness of the coating material to ensure the durability and safety of the H-beam during use.
