| High Light | ASTM A500 Rectangular Hollow Section ，Building Structure Carbon Steel Tube ，Galvanized Rectangular Steel Tube | ||
ASTM A500 Rectangular Hollow Section Carbon Steel Tube is a high-quality structural steel tube manufactured according to ASTM A500/A500M standards. It is produced by cold-forming welded carbon steel into a rectangular hollow section (RHS) with precise dimensions, excellent strength, and reliable structural performance.
ASTM A500 rectangular hollow section tubes are widely used in building structures, steel frames, bridges, machinery manufacturing, and engineering projects due to their high strength-to-weight ratio, good weldability, and dimensional accuracy.
Compared with traditional solid steel sections, rectangular hollow section tubes provide excellent load-bearing capacity while reducing material consumption and overall structural weight. They are an ideal choice for modern steel construction and industrial fabrication.
In modern construction and engineering projects, traditional steel profiles often face challenges such as:
To solve these problems, engineers increasingly choose ASTM A500 rectangular hollow section steel tubes, which provide a combination of strength, durability, and lightweight structural design.
ASTM A500 Rectangular Hollow Section Carbon Steel Tube offers an efficient structural solution through:

ASTM A500 rectangular hollow section steel tubes are widely used in various industries:
ASTM A500 rectangular hollow section tubes work by using their closed hollow geometry to efficiently distribute external loads.
The rectangular cross-section provides:
During construction, rectangular hollow sections are connected through welding, bolting, or other fabrication methods to form stable structural frameworks. The internal hollow space reduces unnecessary material usage, making the structure lighter, more economical, and easier to install.
When selecting ASTM A500 rectangular steel tubes, consider the following factors:
Choose suitable dimensions according to:
Select based on application environment:
For international projects, customers may require:
ASTM A500 rectangular hollow section tube is a cold-formed welded carbon steel structural tube designed for construction and engineering applications. It offers high strength, good weldability, and excellent dimensional accuracy.
ASTM A500 includes four common grades:
Grade B and Grade C are the most widely used grades for structural projects.
ASTM A500 Grade C has higher yield strength and tensile strength compared with Grade B, making it suitable for heavier structural applications.
Yes. ASTM A500 rectangular tubes can be galvanized or coated to improve corrosion resistance and are widely used in outdoor steel structures.
Yes. Manufacturers can supply customized sizes, wall thicknesses, lengths, surface treatments, and additional inspection requirements according to project specifications.
