Hemaokang Steel (Shandong) Co., Ltd. presents our premium 2 Inch Galvanized Steel Pipe Schedule 40 ASTM A53, designed for structural applications that demand strength, durability, and corrosion resistance. As a manufacturer with an annual export value of US$50–100 million and ISO9001 certification, we ensure every pipe meets rigorous quality standards. This 6.0m hot dip galvanized pipe is the ideal choice for scaffolding, fencing, handrails, and building frameworks.
Our pipes are produced from high-quality carbon steel conforming to ASTM A53 Grade B, with a hot dip galvanized coating that provides long-lasting protection against rust and environmental factors. The Schedule 40 wall thickness offers excellent structural integrity while maintaining ease of fabrication and installation. Whether you need plain ends or threaded connections, we can customize to your project requirements.
Below are the key technical specifications and features that make our product stand out in the B2B market.

Key Features & Benefits
- Superior Corrosion Resistance: The hot dip galvanized coating forms a metallurgical bond with the steel, providing protection in harsh environments, including outdoor and industrial settings. This extends the service life significantly compared to black steel pipes.
- High Structural Strength: Schedule 40 wall thickness delivers a robust weight-to-strength ratio, making it suitable for load-bearing structures, scaffolding, and support columns.
- ASTM A53 Compliance: Our pipes strictly adhere to ASTM A53 Grade B standards, ensuring consistent chemical composition and mechanical properties. This is critical for projects requiring certified structural materials.
- Versatile Applications: Ideal for construction, fencing, railing, greenhouse frames, pipe racks, and temporary structures. The 6.0m length reduces joints and improves installation efficiency.
- Customizable Ends: Available with plain ends (for welding or coupling) or threaded ends (for mechanical connections). We can also provide beveled ends upon request.
- Cost-Effective Solution: Compared to stainless steel, galvanized pipes offer excellent corrosion resistance at a lower cost, making them a popular choice for budget-conscious projects without compromising quality.
- Easy to Fabricate: Can be cut, welded, and threaded with standard tools. The uniform coating ensures consistent workability across the entire length.
- Environmentally Friendly: The galvanizing process is recyclable, and the long life of the pipe reduces replacement frequency, lowering overall material waste.
Quality Assurance
Every pipe undergoes strict quality control procedures at our factory in Liaocheng, Shandong. Our ISO9001-certified management system ensures traceability from raw material inspection to final coating thickness measurement. We conduct hydrostatic testing, bending tests, and flattening tests to verify performance. The hot dip galvanized coating is tested for uniformity and adhesion according to ASTM A123/A123M standards.
Our experienced team of 51–100 employees oversees production, and our export volume of US$50–100 million annually reflects the trust global customers place in our products. We serve markets across North America, South America, Europe, Asia, Africa, and Oceania, meeting diverse regional requirements.
We offer flexible packaging options (bundled, strapped, or in containers) and can provide custom lengths, end finishes, and special coatings. For large orders, we can coordinate with logistics partners to ensure timely delivery.
Frequently Asked Questions
-
Q: What is the difference between Schedule 40 and Schedule 80 pipe?
A: Schedule 40 has a thinner wall (3.91 mm for 2-inch) compared to Schedule 80 (5.54 mm). Schedule 40 is lighter and more cost-effective for general structural applications, while Schedule 80 is used for higher pressure or heavier loads. -
Q: Can this pipe be used for water or gas lines?
A: Yes, ASTM A53 Grade B pipe is suitable for pressure piping, but for potable water applications, confirm local regulations regarding hot dip galvanized coatings. For gas lines, it is commonly used in low-pressure systems. -
Q: What is the standard length tolerance?
A: Our standard length is 6.0 meters with a tolerance of +0/-25 mm. Custom lengths can be produced upon request with minimum order quantities. -
Q: Is the galvanized coating uniform on the inside?
A: Hot dip galvanizing coats both the interior and exterior surfaces, but the inner coating may be thinner. For applications requiring full internal protection, consider additional treatment or a heavier coating. -
Q: How should I store galvanized pipes?
A: Store in a dry, ventilated area, off the ground, and avoid contact with moisture or corrosive chemicals. Use proper supports to prevent bending. For long-term storage, consider covering with a breathable tarp. -
Q: Can you provide a mill test certificate?
A: Yes, we provide a mill test certificate (MTC) conforming to EN 10204 Type 3.1 or similar, upon request. This documents chemical composition, mechanical properties, and coating details. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is typically 10 tons. For special sizes or finishes, MOQ may vary. Please contact our sales team for exact requirements. -
Q: How long does delivery take?
A: For production orders, delivery time is approximately 15–25 days after confirmation. For stock items, we can ship within 7–10 days. Actual transit time depends on destination and shipping method.
