What are the Differences between JIS G3444 and JIS G3466
JIS G3444 and JIS G3466 are both Japanese Industrial Standards (JIS) that relate to the construction industry.
1.Application:
The JIS G3444 standard specifies the carbon steel tubes used for general structural purposes. This includes the use of pipes in building construction, bridges, and other structural applications.
The JIS G3466 standard, on the other hand, specifies the square and rectangular steel tubes used for general structural purposes.
2. Shape
One of the primary differences between these two standards is the shape of the tubes they describe. JIS G3444 covers round tubes, while JIS G3466 specifically deals with square and rectangular tubes. Additionally, the JIS G3466 standard also includes provisions for the use of grades of steel different from carbon steel, such as high-strength low-alloy and weather-resistant steel.
3. Minimum yield strength
JIS G3444 specifies a minimum yield strength for the carbon steel tubes it covers, while JIS G3466 does not. This means that carbon steel tubes meeting the requirements of JIS G3444 may be stronger and more durable than those that comply with JIS G3466.




In conclusion, while both LEFIN STEEL JIS G3444 and JIS G3466 deal with steel tubes used in construction, they differ in terms of the shape of the tubes they specify, the types of steel allowed, and the minimum yield strength requirements. It is essential to understand these differences to ensure that the correct standard is followed in the construction process.
