Hemaokang Steel (Shandong) Co., Ltd. is proud to offer 6-meter length galvanized steel pipes with 1.5mm wall thickness, specifically designed for construction projects. Our pre-galvanized pipes provide superior corrosion resistance and long-lasting durability, making them an ideal choice for structural frameworks, fencing, scaffolding, and water conveyance. With a production capacity backed by an annual export value of US$50–100 million, we ensure consistent quality and reliable supply for global clients.
These pipes are manufactured using high-quality steel coils and undergo a strict hot-dip galvanizing process before forming, ensuring uniform zinc coating on both interior and exterior surfaces. The result is a product that resists rust and weathering even in harsh environments. Our ISO9001 certification guarantees that every batch meets international standards for dimensional accuracy, tensile strength, and coating thickness.

Our pre-galvanized steel pipes are widely used in construction scaffolding, greenhouse frames, handrails, fencing, water supply lines, and structural supports. The uniform zinc coating provides excellent protection against corrosion, extending the service life of the pipe in outdoor or humid environments. Compared to post-galvanized pipes, pre-galvanized pipes offer better coating adhesion and a smoother surface finish, which is particularly beneficial for aesthetic applications.
With a team of 51–100 skilled employees and advanced production lines, Hemaokang Steel ensures fast turnaround times and strict quality control. Our main markets span North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, reflecting our ability to meet diverse international standards. We have successfully exported to over 30 countries, with an annual export value exceeding US$50 million.
Frequently Asked Questions (FAQ)
-
Q: What is the difference between pre-galvanized and hot-dip galvanized pipes?
A: Pre-galvanized pipes are coated with zinc before the pipe is formed, resulting in a thinner, more uniform coating. They are ideal for indoor or light-duty applications. Hot-dip galvanized pipes are dipped after forming, offering a thicker coating for heavy-duty outdoor use. Our pre-galvanized pipes are suitable for many construction applications where standard corrosion resistance is sufficient. -
Q: Can you provide custom lengths or diameters?
A: Yes, we offer customization for both length and outer diameter. Please contact us with your specific requirements; we can produce non-standard sizes as per your order quantity. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ for 6-meter pipes is 20 tons, but we can negotiate smaller quantities for trial orders. Please inquire with our sales team. -
Q: Is this pipe suitable for welding or threading?
A: Yes, the 1.5mm wall thickness and pre-galvanized surface allow for easy welding and threading. However, we recommend using appropriate techniques to avoid damaging the zinc coating near weld joints. -
Q: Do you provide test certificates or third-party inspection?
A: Yes, we provide a Mill Test Certificate (MTC) for each batch. Third-party inspection (e.g., SGS, BV) is available upon request at an additional cost. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 15–20 days after receipt of deposit. Custom orders may require 25–30 days depending on complexity. -
Q: How is the pipe packaged for export?
A: Pipes are bundled with steel straps and wrapped in waterproof plastic or woven bags. Wooden pallets or crates are available for fragile or small orders. We also offer container loading consulting to optimize space. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and other flexible terms for long-term partners.
