Hemaokang Steel (Shandong) Co., Ltd. takes pride in supplying high-quality Hot Dipped Galvanized Steel Pipe Round Pre Dip 2mm Thickness Zinc Layer 80μm. As a newly established yet rapidly growing manufacturer with an annual export value of US$50 Million - US$100 Million, we combine advanced production techniques with rigorous quality control. Our round pre-dip galvanized pipes are designed to offer superior corrosion resistance, long service life, and reliable performance across diverse applications. With a dedicated team of 51-100 employees and ISO9001 certification, we ensure every pipe meets stringent international standards, providing you with a cost-effective solution for your construction and industrial needs.
Product Overview: The hot-dipped galvanizing process involves immersing the steel pipe in a bath of molten zinc, creating a robust metallurgical bond. The result is a uniform zinc layer of 80μm thickness on a 2mm wall thickness pipe, offering exceptional protection against rust and environmental factors. This round pre-dip pipe is ideal for applications requiring high durability and low maintenance, such as water supply, gas transmission, oil pipelines, scaffolding, and structural supports.
Key Features & Technical Specifications
- Superior Zinc Coating: 80μm average zinc layer thickness ensures excellent corrosion resistance, extending pipe lifespan by up to 50% compared to standard galvanized pipes.
- Precise Wall Thickness: 2mm wall thickness provides strength and durability while maintaining good formability for bending and threading.
- Uniform Coating: The hot-dip process guarantees a smooth, even zinc layer with no bare spots, reducing the risk of premature rust.
- Versatile Sizes: Available in outer diameters ranging from 1/2 inch to 12 inches, with customizable lengths up to 12 meters.
- Compliance & Standards: Manufactured under ISO9001 quality management system, and can be produced to meet ASTM A53, BS1387, or other international specifications upon request.
- Easy Installation: Round shape facilitates easy connection via threaded ends, couplers, or welding, saving time and labor costs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between pre-dip and post-dip galvanized pipes?
A: Pre-dip (or pre-galvanized) refers to pipes that are galvanized before being cut and threaded, resulting in a uniform coating. Post-dip is done after fabrication. Our pre-dip process ensures full coverage on all surfaces, including threads. -
Q: Can you provide pipes with a zinc coating thicker than 80μm?
A: Yes, we can customize the zinc layer thickness up to 100μm or more, depending on your requirements. Please contact us for details. -
Q: What standards do your pipes comply with?
A: Our pipes are manufactured under ISO9001 quality management and can meet ASTM A53, BS1387, EN 10255, or other standards as requested. We perform regular testing to ensure compliance. -
Q: Are the pipes suitable for drinking water systems?
A: Yes, our hot-dipped galvanized pipes are commonly used for water supply and are safe for potable water when installed according to local regulations. The zinc coating is non-toxic. -
Q: What is the minimum order quantity (MOQ) for this product?
A: Our MOQ is typically 5 tons, but we can accommodate smaller trial orders for new customers. Please discuss your needs with our sales team. -
Q: How do you ensure the zinc coating thickness is consistent?
A: We use advanced magnetic thickness gauges to measure the coating on every batch. Random samples are also tested in our laboratory to ensure the 80μm average is met. -
Q: Can you cut the pipes to specific lengths?
A: Absolutely. We offer custom lengths from 1m to 12m. For longer lengths, please inquire about special arrangements. -
Q: What is the delivery time for a typical order?
A: For standard sizes, delivery is usually 15-20 days after order confirmation. Custom orders may take 25-30 days, depending on complexity.
