EN 10219 S275J0H square hollow section pipes S275J0H structural steel pipe specification

The EN 10219 standard is a technical requirement for cold formed welded hollow section steel in European specifications, of which S275J0H is a common non alloy structural steel. The S275J0H square hollow tube is widely used in fields such as construction, bridges, and mechanical manufacturing due to its excellent mechanical and welding properties. This material has a minimum yield strength of 275 MPa, good impact resistance and weather resistance, and is suitable for a variety of complex environments.

The manufacturing process of S275J0H square hollow tube includes cold forming and welding to ensure high dimensional accuracy and excellent surface quality. According to the EN 10219 standard, this type of pipe needs to undergo rigorous chemical composition analysis and mechanical performance testing, including tensile testing, impact testing, and bending testing, to ensure that it meets the high strength and high toughness requirements of structural steel. In addition, the geometric dimensions and tolerances of the pipes must also comply with standard regulations to meet the precise requirements of engineering design.

In practical applications, the S275J0H square hollow tube has become an important material for modern steel structure engineering due to its lightweight, high strength, and ease of processing characteristics. Whether used for building frames or mechanical support, its performance can meet high standard structural requirements, providing reliable guarantees for engineering safety and economy.
