There are three shapes of steel pipe in ASTM A500 standard.
Round steel pipe: A circle is a common shape. It is commonly used in pipeline systems, support columns and bridge structural projects.
Square steel pipe: The square steel pipe presents a square cross-section profile. Generally, the lower pipe is suitable for building structures and bridge projects, such as beams, columns, frames, etc., and its mechanical properties such as bearing pressure and bending resistance are excellent.
Rectangular steel pipe: Rectangular steel pipe is widely used because of its unique cross-section profile. It is an indispensable part in the field of pipeline transportation and structural support.

ASTM A500 Steel Pipe Grades

ASTM A500 Grade A is made of low carbon steel with a minimum yield strength of 160MPa and low mechanical properties. It is mainly used for non-load-bearing structural engineering with low pressure resistance.
ASTM A500 Grade B has a minimum yield strength of 315MPa, and has good mechanical strength and stability to withstand loads in building structures.
ASTM A500 Grade C has a minimum yield strength of 345MPa, excellent tensile strength and yield strength, and is widely used in the field of building structures.
ASTM A500 Grade D is less used. High mechanical performance requirements, suitable for structural fields under extreme load conditions.
Differences in ASTM A500 grade a/b/c/d pipes

1. 1. We offer ASTM A500 Carbon Steel Hollow Sections in various steel grades including Grade A, Grade B, Grade C, Grade D. 
   2. Each grade has specific chemical and mechanical properties making them suitable for different applications. 
   3. Grade A is commonly used for structural and construction purposes, while Grade B is used for high-strength applications. 
   4. Grades C and D are used for more demanding applications requiring higher strength and toughness.
