HEB280 European standard H-beam 280*280*105*18 dimensional tolerance standard.
HEB280 European standard H-beam is an important steel widely used in construction, bridges, machinery manufacturing and other fields. Its dimensional tolerance standard is one of the key factors to ensure its performance and safety. This article will introduce the dimensional tolerance standard of HEB280 European standard H-beam in detail, and its impact in practical application.
1. HEB280 European standard H-beam size tolerance standard.
The dimensional tolerance standard of HEB280 European standard H-beam mainly refers to the European standard (EN 10034), and its dimensional tolerance includes width, height, web thickness and flange thickness. Among them, the width and height tolerance range is 3mm, and the web thickness tolerance range is 15mm, flange thickness tolerance range is 3mm. These tolerance standards are formulated to ensure the manufacturing accuracy and stability of HEB280 European standard H-beam, so as to improve its bearing capacity and service life.
2. The influence of dimensional tolerance standards on HEB280 European standard H-beam.
1.Bearing capacity: The formulation of dimensional tolerance standards directly affects the bearing capacity of HEB280 European standard H-beam. If the dimensional tolerance is too large, it will lead to a decrease in the bearing capacity of the steel structure, which will affect its safety performance and service life. Therefore, during the production process, the dimensional tolerances must be strictly controlled to ensure that they meet the requirements of the standard.
2.Stability: In addition to the load-bearing capacity, the dimensional tolerance will also affect the stability of the HEB280 European standard H-beam. If the dimensional tolerance of the steel structure is too large, it will lead to a decrease in its overall stability and is prone to deformation and bending. Not only does this affect the appearance of the building, but it can also cause safety concerns. Therefore, it is important to ensure the stability of dimensional tolerances.
3.Manufacturing difficulty: The formulation of dimensional tolerance standards will also affect the manufacturing difficulty of HEB280 European standard H-beam. If the tolerance range is small, the requirements for the manufacturing process are high, and the equipment and processes required to ensure the manufacturing accuracy are required. This increases production costs and manufacturing difficulties, so tolerance standards need to be developed without sacrificing performance.
