ASTM A500 Square Steel Tube Introduction
ASTM A500 square steel pipe is a cold-formed welded structural pipe produced according to ASTM A500 standard. It has a square cross-section and is commonly used in various load-bearing structures such as skeletons, supports, frames and guardrails.
ASTM A500 Square Steel Tube Advantages
High Strength
ASTM A500 square steel tubes are manufactured from high-quality carbon structural steel through cold-forming, achieving a yield strength of over 345 MPa and a tensile strength exceeding 450 MPa, ensuring structural stability and deformation resistance under heavy loads.
High Dimensional Accuracy
ASTM A500 square steel tubes are formed from steel coils using multiple roll forming passes, followed by sizing rolls for calibration, keeping outer diameter and wall thickness tolerances within ±0.5 mm to ensure smooth alignment during assembly.
Machinability
After forming and welding, ASTM A500 square steel tubes undergo uniform annealing to maintain hardness within an optimal range for processing, reducing the risk of cracks or deformation during secondary operations such as cutting, drilling, or bending.

FAQ
Q: What are the standard lengths of ASTM A500 square steel pipe? Can custom lengths be ordered?
A: Standard lengths are generally 6 or 12 meters. We can provide custom-cut lengths based on customer needs, with an accuracy of ±5mm, allowing for immediate production.
Q: What is the production lead time?
A: Standard specifications can be shipped within 3-5 days if in stock. Custom specifications or large-volume orders typically take 15-25 days to complete and ship. The specific timeframe varies depending on the order quantity and process requirements.
Q: What is our after-sales service like?
A: All products ship with a quality inspection report. If any quality issues are discovered during transportation or use, we will provide a free replacement or reissue upon confirmation and cover the shipping costs.
Q: How is ASTM A500 square steel pipe packaged?
A: Typically, it is strapped with steel strapping and covered with waterproof cloth. For export orders, we can use wooden crates or steel frames for reinforced packaging, ensuring protection against moisture, impact, and rust during long-distance transportation.
Q: Does our company have export qualifications and relevant certifications?
A: Our company has legal export qualifications and can provide documents such as Certificate of Origin (CO), material certification, and commodity inspection reports. We also support third-party inspection agencies in issuing test reports.
