ASTM A500 Grade C rectangular steel tubing for industrial shelving

ASTM A500 Grade C rectangular steel tubing is an excellent choice for industrial shelving due to its high strength. The following table compares the key mechanical properties of the different ASTM A500 grades relevant to structural applications.

Grade	Yield Strength (Minimum)	Tensile Strength (Minimum)	Elongation in 2 inches (Minimum, Shaped)	Key Characteristic for Shelving
Grade A	33,000 psi (228 MPa)	45,000 psi (310 MPa)	21%	Basic strength, for lighter loads.
Grade B	42,000 psi (290 MPa)	58,000 psi (400 MPa)	21%	Good balance of strength and formability, commonly used.
Grade C	46,000 psi (317 MPa)	62,000 psi (427 MPa)	21%	Higher strength for increased load capacity.
Grade D	50,000 psi (345 MPa)	65,000 psi (448 MPa)	20%	Highest strength in the standard.

Key Advantages for Industrial Shelving

High Load-Bearing Capacity: The primary advantage of Grade C is its high yield strength (46,000 psi), which provides superior resistance to bending under heavy loads. This makes it suitable for storing heavy items in warehouses or industrial settings.

Durability and Material Efficiency: The high strength-to-weight ratio of Grade C tubing can allow for designs that support significant loads while potentially using less material than lower grades, which might lead to cost savings or lighter shelf frames that are easier to handle.

Good Weldability and Formability: Despite its high strength, Grade C maintains good ductility, which is crucial for manufacturing. It can be welded and cut effectively to create sturdy and reliable shelving frames.
