American standard square tube A500GR.B, C, D all adopt the A500 standard issued by the American Standards Association (ASTM), which means that they have certain specifications and guarantees in terms of quality and performance. At the same time, these steels are cold-formed welded and seamless carbon steel materials, suitable for welded, riveted or bolted bridges and building structures, as well as general structural purposes.
A500 Grade B/C/D rectangular tubes/pipes are widely used in engineering and construction due to their excellent mechanical properties, durability and ability to adapt to a variety of environments. They not only provide high strength and stability, but also perform well in different application environments, from bridges to buildings, to dynamic loads and low temperature environments.
American Standard Square Tube A500GR.B, C, D all adopt the A500 standard issued by the American Standards Association (ASTM), and meet internationally recognized standards in terms of quality and performance. They are suitable for cold-formed welded and seamless round, square, rectangular or special-shaped structural tubes, and can be used for welded, riveted or bolted structures of bridges and buildings, as well as general structural purposes. Its steel density is about 7850 kg/m³ (0.284 pounds/cubic inch). The tubes are available in welded and seamless sizes, with a circumference not exceeding 88 inches (2235 mm) and a specified wall thickness not exceeding 0.875 inches (22 mm).
These steel pipes theoretically inherit the characteristics of steel under the ASTM A500 standard, can withstand high impact, have good compressive resistance, and ensure safety in various harsh environments and high load conditions. They have excellent durability, are made of solid metal, and use processes such as hot rolling or cold drawing to ensure their long service life and long-term stable use.
S355J2 is a high-quality building material with a wide range of applications and stable performance. In the field of construction, S355J2 has become the preferred material for large structural parts due to its high strength and good toughness. Whether it is the load-bearing structure of a high-rise building or the support system of an underground pipeline, S355J2 can ensure the stability and safety of the building. In addition, it also has good weldability and processability, allowing architects and engineers to design and build various complex building structures more flexibly.
In the fields of industry and construction, different types of steel are widely used due to their unique properties and uses. S235JB, S275JB, S355JB and S355JO are several common European standard low-alloy high-strength structural steels, which are particularly widely used in round tubes.
