1. What is the ASTM A252 Grade 3 steel pipe piles?
ASTM A252 grade 3 steel pipe piles are welded structural steel pipes for application as deep foundation support under buildings, bridges, ports, and offshore engineering. There are two welding processes for these pipes: helical submerged arc welding pipe (SSAW) or the longitudinal submerged arc welding pipe (LSAW/EFW).
2. What sizes and lengths are available?
We offer outer diameters ranging from 219 mm to 3000 mm, covering large and extra-large diameter specifications to suit heavy-duty project needs. Wall thickness options span 6 mm to 40 mm. Standard factory lengths of 6 meters and 12 meters are kept in regular stock, while custom cut lengths can be tailored to match specific project demands.
3. What are the material standards and mechanical properties?
Our pipe piles strictly follow the ASTM A252 Grade 3 industry standard. The mechanical performance meets rigorous engineering requirements: minimum yield strength of 345 MPa, tensile strength ranging from 455 MPa to 620 MPa, and a minimum elongation rate of 20%, delivering stable and reliable structural performance.
4. Can I get quality certification and inspection reports?
Absolutely. All our steel pipe piles are manufactured under ISO 9001 quality management systems. We can provide complete official documentation, including third-party inspection certificates issued by SGS, BV and other internationally recognized authoritative institutions to guarantee product quality.
5. How are the steel pipe piles packaged?
All pipe piles are securely bundled with steel straps and separated by wooden blocks during packing to prevent collision and surface damage during transit. We also provide professional outer wrapping and protective coating solutions based on shipping conditions. Custom packaging schemes are acceptable to meet diverse export and transportation requirements.
6. What is the delivery time?
Our general delivery cycle is 15 to 30 days after order confirmation. The exact lead time varies according to order quantity, product specifications and destination port.
7. Is it possible to custom sizes?
Yes, full customization is supported. We can adjust outer diameters and wall thicknesses precisely in line with clients’ unique design and construction specifications to fit different engineering scenarios.
