Products Overview
ASTM A500 is the premier North American standard for electrical resistance weld carbon steel hollow structural sections (HSS). Engineered for optimal strength-to-weight ratio, our square and rectangular tubing delivers superior bending and torsional rigidity, minimizing material usage while maximizing structural efficiency. Fully compliant with the U.S., Canadian, and Mexican building codes, it has become the trusted choice for construction, infrastructure, industrial, and transportation projects across North America, supported by our more than 20-year expertise in supplying HSS to regional market

Key Advantages
▁▁▁▁▁▁▁▁▁▁▁▁▁▁
01
USMCA Origin Compliance
Our ASTM A500 HSS fully meets USMCA Product-Specific Rules (PSR) for HS Code 730630.
02
Testing
Routine tensile, yield, elongation, and ultrasonic testing (UT) are conducted; all quality records are retained for 5 years to meet North American customs audit requirements.
03
Surface Finish
Galvanization and oil coating to enhance corrosion resistance and service life.
04
Cost-Effective:
Electrical resistance weld manufacturing process delivers lower costs than seamless tubing, paired with faster lead times for standard orders to meet tight project schedules.
Products Application
◎ Constructional Engineering
ASTM A500 square and rectangular steel tubes, boasting high strength and excellent toughness, are widely used in scaffolding supports, load-bearing structures, and beam-column systems in construction projects. They are well-suited for commercial buildings, residential properties, and industrial plants across the United States and Canada, with precise scenario matching based on strength grades.
◎ Infrastructure Engineering
After anti-corrosion treatments like hot-dip galvanization, it can resist harsh climates such as rain, snow, and salt spray, meeting the requirements for long-term outdoor service.
◎ Transportation Sector
With the balanced advantage of lightweight design and heavy-load capacity, it has become a core structural material for the manufacturing of trucks, buses, and special-purpose vehicles.
◎ Industrial & Warehousing Sector
Combining high strength and easy processability, it perfectly meets the efficient production and storage needs of the manufacturing and warehousing logistics industries.
