A500 Grade B
A500 Grade B is a cold-formed welded or seamless carbon steel rectangular tube suitable for welding, riveting or bolting in structures such as bridges and buildings. It has good mechanical properties and durability for general structural use. It has a density of approximately 7850 kg/m³ (0.284 lb/in³) and can be produced in a range of sizes up to 88 inches (2235 mm) in circumference and 0.875 inches (22 mm) in wall thickness.
A500 Grade C
A500 Grade C is also a cold-formed welded or seamless carbon steel rectangular tube with similar properties to Grade B. It is suitable for structural applications requiring higher strength and stability. Grade C is typically used where additional mechanical properties are required, such as in structures subject to dynamic loads.
A500 Grade D
A500 Grade D requires heat treatment to improve its low temperature toughness and impact resistance. This grade of rectangular tube is suitable for applications that require good performance in low temperature environments, such as bridges and building structures in cold climates. The mechanical properties and durability of Grade D make it an ideal choice for structures that require high strength and toughness.
Applications
Bridge Construction
A500 Grade B/C/D rectangular tubes are often used in bridge construction, especially in large bridge projects that require high load-bearing capacity and durability. Their high strength and stability ensure the safety and reliability of bridges.
Building Structures
These rectangular tubes are also widely used in various building structures, including high-rise buildings, industrial plants and commercial facilities. Their weldability and easy processing make installation and connection in complex structures easier.
Dynamically Loaded Structures
For structures that need to withstand dynamic loads, such as mechanical devices and transportation equipment, A500 Grade C and Grade D are preferred for their excellent mechanical properties and toughness. These grades of rectangular tubes can effectively resist vibration and impact, extending the service life of equipment.
Low Temperature Environment Applications
A500 Grade D rectangular tubes are particularly suitable for applications in low temperature environments, such as infrastructure construction in cold regions. Its heat-treated characteristics ensure that it can still maintain good toughness and strength under low temperature conditions.
